  1. 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!

  2. 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.

  3. 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

  5. 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.

  6. 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))

  7. 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)

  8. 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"),"")

  9. 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),"")

  10. 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

  11. 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
    Fig13. 10:00 hours shift minus 8:48 = 1:12 Actual overtime H13
    Fig14. 10:00 hours shift, so 11:00 minus 8:48 = 2:12 Actual overtime H14

    Figure H13
    C13 D13 E13 F13 G13 H13
    Shift length Start time End time Hour Work Overtime Actual overtime
    10:00 06:00 15:00 09:00 00:12 01:12
    H13 =IF(C13>F13-TIME(8,48,0)>=TIME(1,0,0),C13-TIME(8,48,0),0

    Figure H14
    C14 D14 E14 F14 G14 H14
    Shift length Start time End time Hour Work Overtime Actual overtime
    10:00 06:00 17:00 11:00 02:12 02:12
    H14 =IF(C14>F14-TIME(8,48,0)>=TIME(1,0,0),F14-TIME(8,48,0),0)

    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.

  12. 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)

  13. 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

  14. 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.

  15. 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

  16. 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.

  17. 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?

  18. 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

  19. 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.

  20. 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.

  21. 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

  22. 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.

  23. 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

  24. 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

  25. 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.

  26. 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

  27. 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.

  28. 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

    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.

  29. 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.

  30. 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

  31. Hello alexander,
    I'm trying to calculate the duration for multiple tasks between differentes dates, like 04/04/2023 08:00:00 and 05/04/2023 10:00:00 in date format.
    But i need to inlude only the working days and hours, which are:
    Opening hours: 08:00 to 16:30
    With mutiple breaks: 10:00 to 10:15 / 11:30 to 13:00 / 15:00 to 15:15.
    The tasks varies wildy in lenght, it can range from 2 hours to 2-3 days.

    Do you know a formula for this calcul?
    Thank you

  32. I'm trying to sum a total of each individual who has worked for the entire week. I have a data that I have calculated the daily working hours but I am unable to get a total of the entire week.

  33. I'm trying to calculate the amount of time I worked down to the exact minute for the entire month, but when I try to sum it it just adds time to each other in a 24 hour format, starting me from 0 again after every 24 hours

  35. Hello, I have huge time data in the format, 00:07:15:20. I want to perform sums, divide them by other number variables to find variable per time, but whenever I change the format it doesn't seem to work instead, it reverts back to a format like this "08/01/1900 08:15:15"

    How do I resolve this?

    1. Hi!
      Your task is not completely clear to me. Explain what your format means and what actions you want to perform. Give an example expected result.

  36. Is there a way to set up a formula to calculate the elapsed hours/minutes only during certain timeframes/days?

    I.e. We want to calculate elapsed time from order received to order sent out. But we only want the elapsed time to calculate from Monday - Friday 8am-4pm. So if an order comes in at 7pm on Monday night, we want the elapsed time to start calculating as of 8am on Tuesday and continuing to track business hours only until the order is sent out.

  38. Drives me nuts. I got time formatted in HH:mm:ss and I try to get the difference between two times in seconds. I always get the output mm:ss if I multiply it by 86400 I get zero.

    Another problem I've encountered is that =(B2-((-9,59)/(465)*125)) outputs a value error. I don't get any of this.

    1. Hello!
      Question 1: Try changing the cell format to General
      Question 2: Check the value in cell B2. Check the decimal separator. Probably correct 9.59 You don't need so many brackets. =B2-(-9.59/465*125)

  39. I am looking to scan a barcode in column A, that then produces the date and time it was scanned in column B. When I use the the formula =IF(A1="","",now()) in column B, and I scan a barcode into A1, the correct time comes up. now when the formula is copied down the column, B2 appears blank (as it should). Then when you scan a new barcode into A2 any amount of time later after the first time, the current time appears in B2 and B1 changes to the new current time.

    I need a formula to calculate the time of the scan in the adjacent cell, that doesn't change unless the adjacent cell changes.

    1. Hi
      I’m trying to create a roster that calculates hours worked and automatically subtracts non paid breaks
      For example if someone works 12pm-7pm it would be 7 hour in total but minus 1 hour for unpaid breaks so the excel sheet should show 6 hours instead of 7.
      I can get the formula to add the hours but not sure what formulas to use to minus unpaid breaks

      1. Hi! Subtract 1 hour from the time difference. For example, by using the TIME function:

        =End time - Start time - TIME(1,0,0)
        or
        =End time - Start time - 1/24

    2. Hi!
      You can use a VBA macro to replace the formula with the current time when you enter a value in another cell.

  40. Hello,

    I have a situation where I calculate the answering time, but I do not want to calculate the time outside of working hours.
    For example:

    Time of receiving e-mail: 02.02.2023. 15:50
    Time of receiving answer: 03.02.2023. 08:30
    I want the result to be: 40 minutes.

    How to do it?
    Thank you.

  44. Hi, Found your tutorials very useful. Kindly help with the below task.

    I'm trying to prepare a weekday-wise task schedule, for item dispatching purposes.
    I require to view the time with WEEKDAY (ie: WED 15:30).
    Ex: If the dispatch day/time of delivery of one item, is WED 15:30, our preparation starts 36 hours prior, so at " Preparation Time" column should be displayed as " TUE 03:30", where I can analyze the hourly workload on each Day of Week.

    Thanks.

    1. Hello!
      To extract the time from a date, extract the fractional part of the number using the INT function.
      For example,

      =IF((A1-INT(A1))>TIME(15,30,0),A1-36/24,A1)

      I hope it’ll be helpful.

  45. Im trying to count timestamps i made with a macro essential enters now() if another cell is filled but i want to count the time stamps that fall into a range of 9am-12am 1pm-3pm and 3pm-5pm any idea how to format timestamps so i can use count ifs to determine if they are within those ranges?

    1. Hello!
      If your values contain time, count the number of values by two criteria using the COUNTIFS function:

      =COUNTIFS(A1:A15,">09:00",A1:A15,"<12:00")

      I hope my advice will help you solve your task.

  46. Anyone have an idea how I can compute for cycle time? But only taking into account a specific timeframe.

    Example:
    Timeframe is 9:00AM to 5:00PM
    But the device was assembled with times:
    8:00AM-12:00NN
    3:00AM-7:00AM
    2:00PM-7:00PM

    Is there a formula where I can compute for the cycle time but only for 9:00AM-5:00PM time?

      This one. I need the formula for this. Thanks!

  48. Hi Guys...how do you convert two times into hours and minutes..

    Example

    6:00 am --start time
    8:30 --- end time

    Answer is 2.50 where the 50 is the 30 minutes divided by 60 (30/60)

    Need the formulae to work on various time differences like this

      1. Thank you as this was extremely helpful

  49. I know the start time 7:41 AM, I know the time out for lunch, 11:38 AM, I know when the time clocked back in after lunch 12:16 PM.
    The person has to work 8 hours. I need to calculate the ending time based off the three known times and the total duration of 8 hours.
    What is the formula for calculating the ending time?

    1. =TIME(8,0,0)-((Lunch Start - Start Time) + (Lunch End - Lunch Start))

  50. I am trying to create a excel formula which will return a result of decimal hours, calcluated from start time, end time and reported down time, currently I am using cell format h:mm AM/PM for start and stop time, and then I manually subtract the minutes reported for down time and convert sum to decimal hours. for example -->

    Raw Data:
    Start time 5:00 AM
    End Time 1:32 PM,
    Minus 87 minutes down time (which also varies daily)
    Manually calculated its 6.08 in decimal hours

    I am looking for a formula and cell format suggestions to have excel do the calculations after start, end and break data have been added to cells.
