  1. How do you convert a negative value from hh:mm to minutes? For example, if you were subtracting 9:00 PM and 7:30 PM and got -1:30, how would you convert that to -90.00?

  2. I'm trying to find a formula that shows under time equation for puch in &out

    1. Hi! Your task is not completely clear to me.To understand what you want to do, give an example of the source data and the expected result.

  3. I have a column of end of work times. I want to know how to sum just the total number of minutes worked past 5 PM. Thanks!

    1. Hi! Subtract the time 17:00 from each value as described in the article above. Use IF function to replace negative time differences with 0. Calculate the sum using SUMPRODUCT function. For example:

      =SUMPRODUCT(IF(C2:C10-TIME(17,0,0)<0,0,C2:C10-TIME(17,0,0)))

      1. IF that worked, I would be very happy. I can't spot the error, but I get an error message.

  4. What is the formula to calculate the working hours between the following (16/11/2023 09:08 and 23/02/2024 14:31) if working hours are Mon-Fri 07:30-16:00

    1. Hi! Use the NETWORKDAYS.INTL function to calculate the number of working days between two dates. To calculate the working hours between dates, try this formula:

      =(NETWORKDAYS.INTL(A1, B1,1 )-2)*TIME(8,30,0) + TIME(8,30,0)-MAX(0,(A1-INT(A1)) - TIME(7,30,0)) + TIME(8,30,0) - MAX(0,TIME(16,0,0)-(B1-INT(B1)))

      Set a custom time format [h]:mm in the formula cell using these instructions: How to show over 24 hours, 60 minutes, 60 seconds in Excel.

  5. Hi.

    I used If function to find night time work hour for shift between 9PM to 6:AM for example clock in 2PM lock Out 10AM result 1 hours. but now i could not remember how to format the function. could you help please? thanks

  6. I'm trying to find a formula that shows the difference between two times (seconds) in percentage.
    For example, Current time is 18.2 seconds and New time is 16.8, how do i calculate the difference to show in percentage. Also what if the current time is 18.2 seconds and the New time is 55.9 seconds, is the formula different? Thanks in advance.

  7. Using a stopwatch with a "lap" function (made with VBA code), time is auto logged in column A as 0:00:00. When I use =SUM for the A cells, it does not auto add the times. (if A2 is 0:00:10, A3 is 0:00:07, A4 is 0:00:15, I put the SUM formula where I want the total to be, but it does not add A2 through A4 and only shows 0:00:00.)

    Once the formula is in place, if I double click the A cells that have time in them and hit enter, then and only then will it add the data.

    How do I get this to automatically add the data when times are added in the A column?

    1. Hi! I cannot help you check how your custom function works, which I don't have. We do not help with the creation of custom functions, and we do not give advice on how to work with VBA.

  8. I'm trying to add seconds to a starting time that's a negative value (say, A2='-0:20:00) but =A2+TIME(0,0,31) is not working even though I went and changed to 1904 date format in advanced options. Where should I go from here? I want negative time before a catalyst event at time=0:00:00. Then see values from 0:00:00, 0:00:30 all the way to 1:20:00 at 30 second intervals.

    1. Hi! You cannot enter a negative time in a cell. But you can get a negative time in the 1904 date format using a formula like this:

      =0-TIME(0,0,20)
      or
      =0-A2
      where A2=0:0:20

  9. Im trying to find a formula to add time.
    Clock in at 10: out at 14: if they get to work before 11 ill pay minimum wage. After 11 they get pay servers rate.
    What will be the formula to add hours before and sfter 11 separste

    1. Hi! To find the number of hours before 11:00, find the difference between 11:00 and the start time. This is described in the article above. If this does not help, explain the problem in more detail. Provide me with an example of the source data and the expected result.

  10. hi there. my question is let say

    10434:34 which is 10434hours and 34minutes + 214:53 which is 214hours and 53minutes
    how to create the formula. since i try but my answer is VALUE.

    please guide me. thank you

  11. hi ,
    =(C1+D1)-(A1+B1)
    i am using this formula for calculating hours. but this formula only for less than 24 hours , how can i use this same formula for more than 24 hours
    thank you

  12. Howa to calculate the repetition of hours 8 and 12 bitween two dates ex: 15/02/2024 and 18/02/2024
    Thank you.

    1. Hi! If you have a range of date and time values, you can use the HOUR function to extract the number of hours in the range. You can then use the SUMPRODUCT function to count the number of hours that is equal to 8. For example:

      =SUMPRODUCT(--(HOUR(A1:A15)=8))

      I hope my advice will help you solve your task.

  13. Hi, I am trying to figure out an average clock-in time on different days.

    Say,

    Day 1: 07:00
    Day 2: 08:00
    Day 3: 06:00
    Day 4: 06:30
    Day 5: 07:00

    I would to know the formula that will tell me the average time the employee clocked in over the 5 days.

    Thanks.

  15. Hi, I am creating a schedule tracker for teammates in excel. When I write the shifts per employee, I utilize one box per day per teammate. So under Teammate "Zach" in box 1 it will say 4:00-13:00, box 2- 4:00-12:00, and box 3- 4:30-16:30. Is there a way to sum the total number of hours for all those days in each box?

  16. I am trying to create a timesheet that automatically calculates the amount of time between 4 times, adding the hours worked and subtracting the lunch time. From there I need 8 hours or less to populate under "regular hours" column, and any overage to calculate under OT hours. I tried to do a sumif and tell it to calculate the hours and minutes, which it did, but it won't accept me telling it to put 8 if it sums to more than 8 hours.Day In

    1. Hi! I don't want to guess by what logic you set Yes or No. Also, it is unknown if the date and time are written in the same cell or if they are 2 separate values.

  18. Hello
    I am needing help try to make a formula to help me with employees time.
    For instance they start at 5:00 AM normally but if they are late (After 5:02 their time doesn't start until 5:15). Also if they clock out before the next quarter hour say 2:40 PM it is rounded down to 2:30 and minus lunch time of 30 minutes daily. I am trying to do this without having to write out the date in the formula as I'm just double checking their math on each individual day i.e. start time A1 end time A2 lunch A3.

  19. Hi.
    I'm working on my work sheet with all kinds of shifts. My shifts can start at any time of day and also end in any time. Of the sime day or next day.
    B4=start date
    D4=start time
    E4=end date
    F4=end time

    I can calculate length of shift, break, day hours but I can't calculate night hours which are only between 22:00 to 6:00 next day.

    As example, cases can be:
    1. Shift starts 1.1.2024 at 18:00 (6:00PM) and ends 2.1.2024 at 2:00 (2:00AM);
    2. Shift starts 1.1.2024 at 0:00 (12:00AM) and ends 1.1.2024 at 8:00 (8:00AM);
    3. Shift starts 1.1.2024 at 23:00 (11:00PM) and ends 2.1.2024 at 7:00 (7:00AM);
    4. Shift starts 1.1.2024 at 6:00 (6:00AM) and ends 1.1.2024 at 14:00 (2:00PM);
    5. Shift starts 1.1.2024 at 16:00 (4:00PM) and ends 2.1.2024 at 0:00 (12:00AM);
    6. Shift starts 1.1.2023 at 15:00 (3:00PM) and ends 1.1.2024 at 23:00 (11:00PM);
    7. Shift starts 2.1.2024 at 0:00 (12:00AM) and ends 2.1.2024 at 7:00 (AM);
    8. Shift starts 1.1.2024 at 23:00 (11:00PM) and ends 2.1.2024 at 4:00 (AM).

    Can somebody help me with formula to count only night hours?

    1. Hi! To calculate night hours at 10:00PM and ends 6:00AM, try this SUMPRODUCT formula:

      =SUMPRODUCT((ROW($1:$360)>MOD($D4,1)*1441) * ((ROW($1:$360)<(MOD($F4,1)*1441+(TRUNC($F4)>TRUNC($D4))*1440)))) / 1440+SUMPRODUCT((ROW($1321:$1800)>MOD($D4,1)*1441) * ((ROW($1321:$1800)<(MOD($F4,1)*1441 + (TRUNC($F4)>TRUNC($D4))*1440))))/1440 + SUMPRODUCT((ROW($2761:$3000)>MOD($D4,1)*1441) * ((ROW($2761:$3000)<(MOD($F4,1)*1441+(TRUNC($F4)>TRUNC($D4))*1440))))/1440

  20. How do I add and subtract time code, used in synchronization in video editing etc. i.e 01:17:04:22 broken out in hours:minutes:seconds:frames. Additionally as there are different time bases for film based vs video based (23.8 frames per second vs 29.97 frames per second) how do you scale for that?

  21. Hi,

    I have these 2 time stamps. the sum of working hours is over 24h.

    11/1/2023 7:33:46
    11/2/2023 8:55:07

    To calculate total hours I use formula: WORKDAY(F1,H1)+MOD(H1-F1,-1) but then if it is over 24h it calculates as 1:21:21

    Help to fix this is appriciated.

    Thank you!

  22. I have to calculate turnaround time for a batch of specimens. I've been provided with two time points per specimen:
    - time of receipt (in hours and minutes, formatted as custom hh:mm)
    - time of processing (date and time in hours, minutes and seconds, formatted as time)
    I've calculated the elapsed time per specimen simply as Time 2 - Time 1, and it appears to give the correct number of minutes.
    e.g., Time 1 = 05:48
    and Time 2 = 05/10/2023 05:55:16
    Elapsed time = 00:07

    I now need the average turnaround time for the batch. Simply using average gives the wrong answer; I've tried reformatting to use consistent formatting; I've tried to use number instead of time, but I can't get it right.

  23. Hi there,
    i'm creating sheet to calculate working hours for my employee ,we have shift timing of 8:30 am to 8:00 PM ,but punching time would vary for each persons ,i have constraint in minusing lunch break,if the person is working from 8:30 am to 1: 30 pm or 2:00 pm to 8:00 pm there wont be lunch break , so i need formula that helps me to calculate exact working hours

    need difference from end date to start date

  25. Hi,

    I'm trying to create a time sheet to be able to track my breaks, also at work I have to track the total minutes that I'm in different meetings throughout the day. For example I have track the total minutes I'm on a phone call, total minutes I'm in different meetings, etc. (in total there could be up to 16 total different things I have to keep track of throughout my shift), also want to track total hours worked for the day and the week and any over time that is being done. For example this is an example of a break down of what I have to keep track of and what my work day can look like and how I have to track it,

    Clock In: 6a
    Office Time 1: 6am- 7:45am
    Break 1: 7:45am-8am
    Phone Time 1: 8am-9am
    Break 2: 9am-9:05a
    Phone Time 2: 9:05a-10a
    Break 3: 10a-10:05a
    Phone Time 3: 10:05a-11:15a
    Meeting 1: 11:15a-11:30a
    Lunch (Deducting 30 min. for Lunch) : 11:30a-12p
    Meeting 2: 12p-12:15p
    Phone Time 4: 12:15p- 1p
    Break 4: 1p-1:15p
    Phone Time 5: 1:15p-2p
    Meeting 3: 2p-2:15p
    Clock Out: 2:30p
    Overtime (Phone Time 5): 2:30p-4p

    The time of the meetings, breaks and phone time may vary and aren't always consistent. I hope I provided an example with enough detail to help create a formula for this. Thank you in advance!

    1. Hi! You write the time intervals as text. Therefore, it is not possible to find the sum of the times from your data. If the start time and end time are written in different cells, you can find the duration of each action as described in the article above. You can then use the SUMIF function to calculate, for example, the sum of the "Break" time. I hope I answered your question. If something is still unclear, please feel free to ask.

  26. Hi, I am looking for a formula to calculate hours worked (end time-start time), but also to subtract 30 minutes if cell B isn't blank. So basically if there is a value in cell B, then subtract 30 minutes from the total time worked. Otherwise, if cell B is blank then don't subtract 30 mins.

    1. I think I figured it out:
      =IF(ISBLANK(B2), C2-A2, C2-A2-TIME(0, 30, 0))

  27. Hello, I have a problem I cannot wrap my head around. I need to calculate overtime (time worked over 8 hours) that happened at night (between 22:00 and 6:00) and separately overtime that happened during the day.
    I have start of the work (I6), end of the work (J6), total time worked (K6), total overtime (L6) and how much time I worked during the night (O6).
    I want to calculate specifically how many overtime hours happened during the night and how many happened during the day.
    Thanks for any help.

    1. Hi! If I understand your task correctly, try the following formulas:
      Day overtime:
      =IF(M6>0,IF(L6>M6,L6-M6,0),L6)
      Night overtime:
      =L6-O6

      1. Hey! Thanks a lot for an answer. As much as I like simplicity of this solution (and I got really excited to see it working), it doesn't work for all the cases. For example starting work at 9PM and working until 9AM shows 4 night OT hours, but it should be 1 night OT hour and 3 day OT hours.

        1. For those interested: Formulas that ended up working for me in all the cases were:
          Day overtime (M6);
          =IF(I6<=J6,MIN(L6,MAX(0,"22:00"-I6-"8:00")),MIN(L6,MAX(0,J6-"06:00")+MAX("22:00"-(I6+"8:00"),0)))
          Night overtime(N6):
          =L6-M6
          And no, I didn't think of that myself x)

  28. I need help regarding my formula.
    cell B3: 1/5/2023 18:38
    cell C3: 1/5/2023 18:47
    cell D3: 0 days, 0 hours, 9 minutes, and then the result for cell E3: Failed,
    but the formula for cell E3 is =IFERROR(IF(D3<="0 days 0 hours 15 mins","Passed","Failed"),""
    formula for D3 is =IFERROR(INT(C3-B3)& "days" & HOUR(C3-B3)& "hrs" & MINUTE(C3-B3)& "mins","")
    The format for cells B3 and C3 is custom "mm/dd/yyyy hh:mm."
    should be the correct result for cell E3 is passed if the formula is less than 15 minutes.

    1. Hi! There is a text in cell D3. You cannot do any mathematical operations on the text, and you cannot do comparisons < and >. Try this formula:

      =IFERROR(IF(C3-B3<=TIME(0,15,0),"Passed","Failed"),"")

  29. HI

    I am looking to complete the following in time value

    start time
    finish time
    total hours (finish time less start time)

    I need then if the total hours are greater than 0, deduct 30 minutes lunch

    I cannot figure out the latter part :(

    1. Hi! Please re-check the article above since it covers your case. To subtract 30 minutes, use the TIME function:

      =IF(B1>A1,B1-A1-TIME(0,30,0),"")

  30. Hi
    So let's just say I have data in C:C
    All data is represented as h:m:ss AM/PM based on a form
    eg. 1:58 AM, 3:20PM, 2:23PM, 2:39PM.... the list goes on
    How do I count the hour and any minute associated during the AM/PM

    eg. (1) 1AM
    (1) 3PM
    (2) 2PM

    I have used =COUNTIF(C:C,"="&TIME(12,0,0))
    to check the total pm

    However I was experimenting with those formulas and I've gotten close to it but when proof checking it's not giving me the accurate data per hours

    Please feel free to help/ correct me
    Thank you in advance

  31. I work 10 hour shifts. Overtime start after 8:48. There are times I exceed my shift length or working less hours
    Both formulas in H13 and H14 calculate correct, individually. Not vice versa
    Have to combine both formulas Fig H13 and H14 to get one formula in H

    1. Hi! Sorry, it's not quite clear what you are trying to achieve. Explain the result you want if your two formulas use the same conditions.

      1. Hi! need help on what formula to use to get the total overtime. our official time out is 8:00PM and our store closes at 9:00pm but when we exceed at 9:15PM it is considered as 1hr & 30 minutes overtime already. Can't figure out on how to set the formula that authomatically counts it as 1.5 hrs overtime.
        Given F6 as start time and G6 as end time.
        Thank you in advance.

      2. If i work 9 hours then the formula works in H13 shows the right time 1:12. Fig H13 Shift length - 8:48
        So does the formula in H14. Hours worked - 8:48
        But when i insert H13 formula in H14, i get 1:12 hours instead of 2:12.
        Same happens if i insert H14 formula in H13, i get 00:12 hours instead of 1:12
        So if i want the right time to show in H, i have to change the formula every time.
        The last piece of the formula in C13-Time(8,48,0)0) Shift length - 8:48, i have to change to F14-Time(8,48,0)0) Hours worked - 8:48
        In H13 i have to deduct 8:48 from Shift length
        In H14 i have to deduct 8:48 from Hours worked
        That's why i need one formula in H so i don't have to change the formula every time i work less or more than 10 hours
        Hope my explanation helps

        1. I’m not sure I got you right, since the description you provided is not entirely clear. However, it seems to me that the formula below will work for you:

          =IF(F13<=TIME(10,0,0), IF(C13>F13-TIME(8,48,0)>=TIME(1,0,0),C13-TIME(8,48,0),0), IF(C13>F13-TIME(8,48,0)>=TIME(1,0,0),F13-TIME(8,48,0),0))

          Combine two formulas using the IF function to perform calculations on the condition. I hope I guessed this condition correctly.

          1. Thanks so much

            Tried it and its working 100 percent for me.

  32. Hello,

    I want to find the STARTING CLOCK time for a sequence of tasks where I know and can enter the DURATION time of the needed tasks.

    I do simple subtraction of durations from one column and Excel is correclty displaying the correct startging CLOCK time in another column, but the moment a duration puss the clock backwards past midnight it breaks and shows a line of #######

    Any suggestions?

    1. Hi! If the end time is longer than the start time, then you need to add 1 day to their difference:

      =IF(A1 > B1,B1-A1+1,B1-A1)

  33. I'm trying to calculate the decimal hours and minutes worked when the shift starts at 10:00am an goes through to 2:00am the following morning
    This is what I get:-
    Open Hours
    A B (B-A) =C
    Open Close Hours ON /Day
    10:00 2:00 -8.0 hrs

    Is there a formulae that will show the correct decimal hrs:mm worked when spanning 2 days. (I am not concerned about the days) and jusst enter the hours and sec using as time filter eg 10:30
    Open Hours
    A B C=?
    Open Close Hours ON /Day
    10:00 2:00 16.0 hrs

  34. Hello

    I am working on a timesheet for staff and I am looking for a way to calculate how much time is spent working after 8pm if someone works that long. It would be in hh:mm.

    1. Hi! If I understand your task correctly, try the following formula:

      =IF(A1>TIME(20,0,0),A1-TIME(20,0,0),0)

      Use the TIME function to set 8PM, and the IF function to find the difference if the end time of A1 is greater than 8PM.

  35. I am trying to use Excel 2007 to identify and display fastest times for each stroke, distance, and course (yards/meters) from a sheet with multiple meets, each with multiple strokes and distances, courses and times (formatted in min:seconds:hundredths (mm:ss:00)). I hoped to use Min(IF with an array function but can' get it to work. The function looks like this: (in a different version I used = instead of commas)

    {=MIN(IF(D4:D100,D4,IF(E4:E100,E4,IF(F4:F100, F7,IF(F4:F100,F4,G4:G100)))))}

    Where D = stroke (Free, Back, Breast, etc.) , E = Event distance (50, 100, 200, etc., F= course (yards or meters), and G = times achieved in minutes,seconds, and hundredths or seconds and hundredths where applicable.

    The result I keep getting is 0:00.00 instead of the fastest time.

    I'll have separate functions for each combination of stroke, distance, course. Ideally, I would like to grab the data from a separate sheet where I enter meet results but that is the least of my problems

    1. Hi! If I understand your task correctly, the following formula should work for you:

      =MIN(IF((($D$4:$D$10=D4)*($E$4:$E$10=E4)*($F$4:$F$10=F4)*G4:G10)>0, (($D$4:$D$10=D4)*($E$4:$E$10=E4)*($F$4:$F$10=F4)*G4:G10), ""))

      In your Excel, you need to enter this formula as an array formula.

      1. Thanks!

        I haven't tried your version yet to see how it differs, but think by using TIMEVALUE I was able to omit the the first expression. I stumbled on my version after hours searching the web and experimenting before I saw yours. (As you can see, my data is on a separate sheet named Log.)

        {=MIN(IF(Log!$D$4:$D$39=Log!$D$5,IF(Log!$E$4:$E$39=Log!$E$7,IF(Log!$F$4:$F$39=Log!$F$4,TIMEVALUE(Log!$G$4:$G$39)))))}

        My next problem is how to automatically retrieve the date of the fastest time so it displays on my summary sheet . I entered dates into the Log as M/DD/YYYY and formatted to display as dd:MMM:YYYY. I used a single leading quotation mark to prevent the time from changing to a date when I click on it and to suppress the leading zero.

        I tried using a modified version of the min. time function, but that returned the oldest (smallest) date in the range : ~ ) then I tried using a couple of simple IF formulas: IF( G - B = 0) , B = G, etc. they all returned either "False" or "Value" I think my problem is with TIME formatting

  36. My job keeps a running total of time hours and minutes. For example my running total 2 months ago was 1410:51, last month my total was 1486:33. How do I find the difference between the 2 without excel converting it to days?

    2. You will want to set the number format to the following: [h]:mm which will show as 75:42

      If you leave out the square brackets around the H, then it will show the time as an hour on a clock instead of the total hours. That will show as 3:42.

      To change the format go to Home > Number then click the little arrow in the bottom right. In the left box click "Custom" then type in your custom number format.

  37. I am trying to calculate my time throughout the day which includes a clocked in and out break. But with my formula it is showing what should just be an 8.30 day worked as 8.50. How do I fix this?

  38. Hi Alexander Trifuntov/Ablebits Team.
    I Currently have a column with the data of time elapsed for cars parking in a parking lot. format 00:00:00 H:M:S
    i created the column using this formula =text(P665-L665-int(P665-L665),"HH:MM:SS")
    and then formatted the column with the basic format function into Format>Number>Duration

    i am trying to count the frequency that the time elapsed is over 2 hours (02:00:00). meaning the number of times a vehicle stayed longer than 2 hours.

    any assistance would eb deeply appreciated

  39. hello,

    I am looking for a cycle time formula for seconds. I work in manufacturing and have to track cycle times between pieces produced and then separately track the average time spent per piece.

    1. Hi! Have you tried the ways described in this blog post? If they don’t work for you, then please describe your task in detail, I’ll try to suggest a solution.

  40. Hello,

    I want to be able to create "out" times on a work schedule. Basically any time in a 12hour format input for the "in" column would auto populate an "out" time by adding 6 hours to the input.

    Thank you

    1. Hi! Pay attention to the following paragraph of the article above: How to add or subtract hours to time in Excel.
      It covers your case completely.

  41. Hi! I am needing to calculate an arrival time for a surgical unit. We use the Time of surgery (in 24hr time) + duration of surgery (in minutes) + 1hour for recovery. I'd like to program this calculation into a spreadsheet that we can use for patient flow. Ex. surgery time 0830, duration of 120 minutes + 60 minutes of recovery = arrival time of noon (1130). How can I write a formula to make these conversions properly?
    Thank you!
    Karin

    1. Hi!
      If I understand your task correctly, the following formula should work for you:

      =A1+(120+60)/1440

      A1 - surgery time

  42. I am working with a time sheet. I want a formula. Our working hours is 9:00 hrs. So, if a person works for 9:00hrs or more, I want to map it to 8:00 hrs and remaining in overtime cell. can you please help?

    1. If you want a formula, explain in detail what result you want. The information you provided is not enough to understand your case and give you any advice.

      1. The Formula I want is to map 9.00hrs or more to 8 hrs.

  43. I am trying to figure out a formula for our time sheets. We have the work hours, that isn't the issue. My problem is converting the work hours to clock hours. For example someone works 7:30 hours, that is how we get it I have to then convert it to 7.50 to figure payroll. Does that make since what I am asking. Example of what we do
    5/15/2023 1:15 PM 3:14 PM 1:59 1.98
    Date clock in clock out hours worked I convert this manually looking for a way to automatically do this
    Thank you

  44. Hello, I am trying to subtract overtime hours from regular hours that are on 2 different cells but I keep getting #VALUE error

    Example: In cell A2 I have [42]:15 for total worked hours and in cell B2 I have [40]:00 for regular work hours
    The difference would be =A2-B2 to get a total of [2]:15, meaning 2 hours and 15 mins of overtime but I keep getting #value error.

    note: I am not working with date or time formats I would say, since they are hours worked, not time of the day

    I would appreciate your response

  45. Hi Alexander Trifuntov/Ablebits Team.
    With the condition:
    The working hours are Monday to Saturday from 09:00 AM - 06:00 PM and Sunday from 02:00 PM - 08:00 PM.
    Holiday only on public holiday (e.g. May 1, December 25)
    Ticket received on April 30, 2023 at 05:30 PM
    Ticket responded on May 2, 2023 at 09:30 AM

    Could you please help me, what is the Excel formula to calculate the timestamp difference above (in hours) excluding public holidays?

    1. Hi! Your request goes beyond the advice we provide on this blog. This is a complex solution that cannot be found with a single formula.

      1. Hi Alexander, really appreciate the response.
        How about with more simple condition:

        The working hours from Monday to Sunday from 09:00 - 18:00
        Full holiday (no working) only on public holiday such as January 1, May 1, December 25
        A. Ticket received on Sunday, April 30, 2023 at 17:30 B. Ticket responded on Tuesday, May 2, 2023 at 09:30

        What is the Google sheets formula to calculate the working hours of timestamp difference between ticket received and ticket responded above (in minutes)?

        The expected answer is 60 minutes: I have 30 minutes left on Sunday but still not responded, skip on Monday because it is holiday, and used 30 minutes on Tuesday to reply it.

        Tried to use NETWORKDAYS.INTL but it does not work. Really appreciate with your help.

  46. Hi,
    Can any one help me find solution for below

    When I'm downloading attendance from biometric machine, I'm noticed that punch in punch out will showing in single cell, now I want to find a formula for generate total working hour and OT,
    The main problem is I need to check each cell for total 30 days in month for a single person,
    And we have more then 400 people working, I'm calculating manually total 30x400, may i know is their any alternate solution
    Ex: 6:00 17:37

    I'm get like this

    1. Unfortunately, this information is not enough to understand what you need. Please describe your problem in more detail. Include an example of the source data and the result you want to get.

      1. Sir, there is no option for uploading an example pic, can you please suggest me alternate way

  47. I'm trying to calculate running hours for a fleet of vehicles over a week, however, I am encountering a problem - All vehicles are on the same sheet, each recognized by a unique code (multiple pieces of data are recorded for the vehicles each day, based on which vehicles are used. Not all vehicles are run every day.) I'm trying to implement a formula that can be carried from one week to the next and doesn't need to be re-coded each week based on the location of the vehicles on the sheet.

    In a nutshell, I need a variant on the "CountIf" or 'SumIf" formulas so that the program can recognize the vehicle codes, and then calculate the difference between the smallest and greatest number of hours. Would this be possible?

    1. Hi! I don't have your data, so I can't recommend any formula. But here is a detailed instruction for the SUMIF function to calculate the amount of time for each vehicle. If this is not what you need, explain in more detail.

  48. Hi, my organisation requires we complete our time sheets using excel. The date is selected via a drop down menu where it then automatically populates the next field with the actual day. My big problem are the start and end times where the columns AM and PM columns are separated and once again are selected by a drop list where either AM or PM can be selected. We are paid from start to end time over that 24 hour day minus the number of hours we actually slept during that overnight shift, In the next column after sleep time, I want to input the required formula to provide the number of hours accumulated as awake, (start to End on the following day) minus the sleep time. How would this be done noting I can't change the existing spreadsheet layout and only add the additional column after sleep time with my own calculations. Thanks

    Date SHIFT Client Start End Shift Type Sleep Time
    12/04/2023 Wednesday ACA Bob 10.45 AM 9.00 AM Day Shift 11pm to 6am
    13/04/2023 Thursday ACA Bob 9.00 AM 9.00 AM Sleepover 11.45pm to 6am
    14/04/2023 Friday ACA Bob 9.00 AM 9.00 AM Sleepover 11pm to 6am

    1. Hi! You can calculate the number of hours like this:
      (11pm - 10.45 AM) + (9.00 AM - 6am)
      I can't give you the formula because I don't know what cells your data are written in.
      If this does not help, explain the problem in detail.

  49. Hello,

    so I am trying to make a timesheet for my employee. I have their start time and end time of work. when I try to calculate total time they worked using timevalue formula, it gives me result in time format.

    for example, I have start time on c2 which is 5:45am and end time on d2 which is 7:45am , so I am trying to calculate hrs he worked using formula, but end result is 2:00am.

    how can I just get a hrs in Number but not in a time format.

  50. Hi,

    I am working on a document for my work to calculate times. Basically i need to have each block typeable for later use to where the calculation is still there for future use. That's the first hurdle. The second i have kind of figured out is to calculate the hours for next to be picked up (i.e. 4 hours , 5 hrs and so on. Then if the time falls into certain hours time frame i need it to factor the added time plus some because we cannot deliver at those times. Thank you
