  1. One Hour 1000/- 1.30 hours How Many Amount Formals

  2. Hello!
    I am using =INT(K2-J2) to calculate the dates elapsed on for cells showing mm/dd/yyyy hh:mm:ss. In the cell the time is shown in military time, once I click into the cell the bar at the top shows the time in AM/PM. I am saying this because I think I have a data/formatting issue I can't resolve. I am also using =TEXT(K3-J3-INT(K3-J3),"HH:MM:SS"). These work okay although ideally I would like to not have to use two different cells to show the difference in days and times and have them combined in one cell... but I am picking my battles.

    The main issue that I am having is that I can't sum or average (i am really just trying to average here) the hour time lapse using =TEXT(K2-J2-INT(K2-J2),"HH:MM:SS"). I either get a div/0 error message or a 0. I have changed the formatting in these cells to various times, date and customs formats and nothing works.

    Additionally, I have another column with h:mm:ss formatting with values only and no calculation and I am able to average the data no problem. I am at a loss because I have copied the data and pasted in another cell so that no calculations were present in that column but still nothing...Im at a loss. Any help would be appreciated.

    1. Hello!
      Unfortunately, without seeing your data it is difficult to give you any advice. Please provide me with an example of the source data and the expected result. It’ll help me understand it better and find a solution for you.

  3. Hello,
    I'm trying to create automatic production schedule. Work hours are from 7:00 to 23:00. I have current date and time. Work that requires 19 hours to complete.
    Need a formula that would pull up current date/time, add 19 hours and show end date/time but in respect to work hours. So if current time is 15:00 it should report end time to be next day at 18:00

    Any help?
    Thanks!

    1. Hello!
      If I got you right, the formula below will help you with your task:

      =IF((HOUR(A2)+B2)>23,A2+TIME(B2,0,0)+TIME(8,0,0),A2+TIME(B2,0,0))

      A2 - current date/time, B2=19
      I hope my advice will help you solve your task.

  4. I need to get hours worked from a start time and end time. Then from that I need a new cell to add them up over a week and get total hours worked that week. Then I’m a new cell I need total hours for the week and hour pay

  5. I need to add data with how long it takes for an agent to complete a workflow. For example, an agent may take 3 mins and 51 seconds for 1 workflow. When I use the time format in Excel, even when I create custom ones in Excel, I'm having a hard time with it showing as 3:51, where 3 is the mins and 51 is the # of seconds. It always ends up showing as hours and mins or the time of day with AM/PM. How can I just get it to just show as 3:51, 3 mins, and 51 seconds. I need to add a lot of data and calculate the averages.

  8. Hi!

    I'm looking a formula to find the time difference between 2 dates, but i don't want to use Cell A1-B1.
    Is there a formula which I can input date and time, and substract both in a single cell?

    So the 2 dates are:
    Commenced - 08/09 0330hrs
    Completed - 11/09 1510hrs

    I should get 3D 11H 40M, but i don't want to utilize 3 different cells to get the answer.

    Appreciate your help!

  9. hello. help needed,,, if possible pleasei have a run out time but what i need is
    if time is 3:30 (fixed ) computer clock say 2:45 (live) when clock reaches 3:30
    and though out the day 5:30, 6:14 etc;
    i would like for rows to totally turn red (as in late) and if i tick a box at end of row i would like it to turn green.
    (a2- a10)

    any help please

    1. Hi,
      Your task is not completely clear to me.
      Could you please describe it in more detail? What result do you want to get?
      Describe exactly the conditions that you want to use in conditional formatting. Give an example of the input and the desired result.
      Here is the article that may be helpful to you — Excel conditional formatting for dates & time.

      1. if somebody has to report in for work at i.e. 05:15 and they do not report in I want the excel row to auto highlight (red) when they report in and I tick a box at end of row hightlight to turn green,

        A1 (fixed number 05:15) , H1 now() so when now() passes A1 fixed time colour change (hightlight) also need to work out formula for this and when i tick the I1 it changes colour

        hopefully you can help!

  10. =IF(B2<A2,B2+1,B2)-A2 I AM USING THIS FORMULA TO FIND TOTAL WORKING HOURS OF AN EMPLOYEE.
    IF ONE EMPLOYEE ABSENT MEANS I ENTER ZERO VALUES IN TIME IN AND TIME OUT CELL .BUT ITS NOT WORK.
    MY DOUBT IS IF ONE EMPLOYEE ABSENT MEANS HOW TO AND VALUE ENTER IN TIME IN AND TIE OUT CELL.

    1. Hello!
      Sorry, I do not fully understand the task. If A2 and B2 are 0, the formula returns 0. Please describe your problem in more detail.
      Explain exactly what the problem is. Give an example when the error appears. It’ll help me understand the problem you faced better and help you.

  11. is it possible for the below formula to be working days not just days??

    =IF(INT(M5-I5)>0, INT(M5-I5) & " days, ","") & IF(HOUR(M5-I5)>0, HOUR(M5-I5) & " hours, ","") & IF(MINUTE(M5-I5)>0, MINUTE(M5-I5) & " minutes and ","")

    TIA
    Steph

    1. Hello!
      I believe the following formula will help you solve your task:

      {=SUM(--(WEEKDAY(ROW(INDIRECT(INT($A$1)&":"&INT($B$1))),2) < 6))-2 + B1-A1-INT(B1-A1)+(MOD(B1,INT(B1)) > MOD(A1,INT(A1)))}

      This is an array formula and it needs to be entered via Ctrl + Shift + Enter, not just Enter.

      Use custom date format

      d "d." h "h."m" min."

      I hope I answered your question.

  12. Hello!

    I need a formula which counts the transaction from (Date, 00:00:01 to 23:59:59) 24 hours and the count after 23:59:59 should go to next date.

    1. Hi,
      I’m sorry but your task is not entirely clear to me. Could you please describe it in more detail? What result do you want to get? Give an example of the source data and the expected result.
      Thank you!

      1. Hello Alexander,

        I am trying to figure out a formula, which will calculate the transaction counts for a day (example: total transaction count for 18-Nov-20 (00:00:01 to 23:59:59) will be 100nos). Also, the counts that are calculated after (18-Nov-20 (00:00:01 to 23:59:59)) should fall to next day (19-Nov-20).

        Is there any formula that you can suggest?

  13. Hello, I need a formula that will help me determine how many calls were happening at 3:00 PM on 11/16. I need to figure out if 11/16/2020 3:00 PM falls between two dates and times.

    For example in row 2 I have join time and leave tine columns with the following data:
    I2: 11/16/20 1:00 PM J2: 11/16/20 1:01 PM
    I3: 11/16/20 13:40 J3: 11/16/20 14:30

    I have about 200 rows with date and times to go through so I need to see if the 11/16/20 3:00 PM date and time falls in between the dates above as well as the other rows. I need an output for each row (whether its true or false).

    After I get this data I can use a count formula to see how many times I get yes which will determine how many calls were happening at 3:00 PM on 3/16.

    My data expands over 48 hours.

    1. Hello!
      The formula below will do the trick for you:

      =AND(M1 > I1,M1 < J1)

      After that you can copy this formula down along the column. I hope my advice will help you solve your task.

      1. Thank you for the information. Do I need to format the dates and time a certain way or format them as something? It's just returning no for everything when I most definitely have some Yes ones.

    2. I should have mentioned the date AND time are both in one column, it is not separated. I need to keep the date and time together.

  14. How do i subtract from (29 minute:17 second:13 millisecond - 28 minute:15 second :90 millisecond) in excel

    1. Hello!
      Write in cells

      00:29:17.013
      00:28:15.090

      Use custom format h:mm:ss.000
      Subtract the second from the first value.

  15. Good afternoon, I have some days where I clock in at 5:00 am out at 11:00 back in 30 minutes later and then out at 1:30pm. But then there are some days in which I will be in and out 3-4 days in a day. example would be Monday 5:00 - 11:00, back in at 11:30 and work till 1:30. But today because I have to go into the office it would be 5:00 - 8:30, 9:15 - 10:30, 12:00 - 2:00, 4:00 - 6:00 pm. I have tried using: =IF(OR(B2="",I2=""),"",(C2-B2)+(E2-D2)+(G2-F2)+(I2-H2)) but the time will not round and I'm still coming up short. Whatever suggestion you have it would be TRULY APPRECIATED because I hate to have to make up time when I'm short 1 day and over the next.
    Sincerely,
    Frustrated!!!

    1. Hi Alexander, I need a formula that tracks multiple times that I would clock in and out of work. Clock in the morning, then clock out for break, back in from break, then out for lunch, clock back in from lunch, then out for break, then return from break, then out for a second afternoon break then clock back in from that break until I clock out for the day.

      example:
      clock in at 5:00 AM, out at 7:00 for 30 minutes then i clock back in at 7:30, work from 7:30 until 11:00 then it's lunch from 11:00 am until 11:30 then i clock back in, then at 1:00 PM I clock out for 30 minutes and return at 1:30 until the end of my shift.

      so any formula you could share would be greatly appreciated.

      1. Hello!
        I don't know how the data is written in your table. If each arrival at work and breaks in work are written in one line, then the formula may be as follows:

        =C2-B2+E2-D2+G2-F2+I2-H2+K2-J2+M2-L2+O2-N2+Q2-P2

        If there is anything else I can help you with, please let me know.

        1. Alexander the formula works great. One last tweek if you don't mind. Our systems rounds up when keyed. I do truly appreciate your assistance, maybe i can stay out of trouble now. :)

          1. Hi,
            Please explain in more detail which results are being rounded. What exactly is the problem? Explain in more detail.

            1. the formula for time adds up across the cell and was wondering if there was a way to get the ending balance to round up? say i worked for 8 hours and 37 minutes, how to get this 37 minutes to round up to 45 minutes?

    2. Hello!
      I’m sorry but your task is not entirely clear to me. For me to be able to help you better, please describe your task in more detail. Please specify what you were trying to find and what problem or error occurred. Give an example of the source data and the expected result.

  16. 1st condition = should be after 8:30 AM
    2nd condition = should be before 4 PM
    Cannot find the right date. Struggle with AM/PM thing (confuse)
    for eg.

    =if(and(10:20 AM>=8:30 AM,10:20 AM<=4:30 PM),"within","out")

    note: 10:20 here is random time.
    Could you help whats wrong with formula and how can I get the right condition?

    1. Hello!
      If I understand your task correctly, you need to use TIME function to compare time

      =IF(AND(A10 >= TIME(8,30,0),A10 <= TIME(16,30,0)),"within","out")

      Hope this is what you need.

  17. hello, how to calculate times between 9AM-9PM and 9PM-9AM if I have '14-Jan-20 05:00' (F2) as a reported date and '15-Jan-20 13:00' (G2) as a resolved date? Thank you in advance :)

    1. and the output that I expected is 16:00 (means 16 hours) for 9AM-9PM and also 16:00 for 9PM-9AM :)

      1. Hello!
        I wrote this formula based on the description you provided in your original comment. My result is 12 hours. Explain your calculations. Does 9 PM-9AM mean 21:00 - 09:00? Are you subtracting time or date and time? It is impossible to understand from your question.

  18. John,
    Wouldn't that cause a circular reference?
    C9: 8:30
    B9: 19:30 (which baffles me to put the End time in B and Stat time in C...?)
    Then, in D9, we subtract those two AND subtract D9 itself from that?... ???

    1. Hello!
      I didn't quite understand your problem. But it might be useful.
      If start time is greater than end time, then you need to add 1 day to their difference

      =IF(A1 > A2,A2-A1+1,A2-A1)

      I hope this will help

  19. what's the added formula if 1 hour must be deducted if you accumulated 6 hrs of overtime everyday?

  20. I am making a spreadsheet to fully calculate how much pay I'm getting the only variable I'm stuck on is that I get paid %15 extra/hour after 6pm on weekdays. Is there a formula that checks for a time after 6pm and can return a value?

    Thank you if anyone can help.

    1. Hello!
      Without seeing your data it is difficult to give you any advice. If time is written in cell A1, then you can compare it using something like this formula:

      =IF(A1>TIME(18,0,0),B1,0)

      I hope this will help, otherwise please do not hesitate to contact me anytime.

  21. I need to figure out how can i get event time/run time of every account having multiple transactions, i need time duration between First till last transaction of every account, every account having multiple transactions count.

    2. All data is in one sheet, first column having account number, then amount then date time then type

  22. Hi there!

    I'm trying to track improvement in running times (e.g. how much faster someone is running 5km).
    So I was wondering if it is possible to subtract one running time (35 minutes 10 seconds) from a better running time (25 minutes 30 seconds) to see how much faster someone is running (-9 minutes 45 seconds).

    1. Hello!
      I hope you have studied the recommendations in the tutorial above. It contains answers to your question.
      Pay attention to the following paragraph of the article above: Formula 3. Count hours, minutes or seconds between two times.

  23. Hey I have a timesheet that I would like to calculate the specific hours given is counted as overtime 1 which is from 22:00 PM - 06:00 AM, time after 06:00 AM will be calculated as overtime 2. I wanna get the hours worked in oveRtime 1 is how many hours? is that possible.
    For example:
    TIME IN (A1) = 12:00AM
    TIME OUT (B1) = 11:00 AM
    hours worked in overtime 1 is 8 hours, and in overtime 2 is 5 hours.

  24. hey so i have a timesheet for work i need it to calculate total hours, overtime 1 and overtime 2
    where hours from 07:00-15:00 is normal hours so no overtime counted
    hours from 15:00-17:00 is counted in overtime 1
    and all other hours is counted in overtime 2
    like so
    if A1(start time)=07:00 B1(end time)=19:00 C1(total hours)=12 D1(overtime1)=2 E1(overtime2)=2
    or A1(start time)=04:00 B1(end time)=16:00 C1(total hours)=12 D1(overtime1)=1 E1(overtime2)=3

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

      =B1-A1

      =IF(AND(B1>TIME(15,0,0),B1<TIME(17,0,0)),B1-TIME(15,0,0),TIME(2,0,0))

      =IF(B1>TIME(17,0,0),B1-TIME(17,0,0),0)

      I hope it’ll be helpful.

  26. Hello.
    I'm looking for a formula. I made one that gives the total worked hours. But my problem is, let's say the office time starts at 8am, the formula includes the time over or under 8am which the minutes for late and early in is computed.

    1. Hello!
      If start time is greater than end time, then you need to add 1 day to their difference

      =IF(A1 > A2,A2-A1+1,A2-A1)

      I hope this will help

    Max time stamp: 2019-09-14 09:16:12.310

    1. Hello!
      Find the difference between these dates using normal subtraction. To determine the difference in time in days, hours, minutes and seconds, apply the formula to the cell with the result:

      =INT(A1)&" days "&INT(MOD(A1,INT(A1))*24)&" hours and "&MINUTE(A1)&" minutes, "&SECOND(A1)&" seconds"

      I hope my advice will help you solve your task.

      1. I need for milliseconds as well. Above works until seconds only.

        1. Hi Alexander Trifuntov (Ablebits.com Team),

          =INT(A1)&" days "&INT(MOD(A1,INT(A1))*24)&" hours and "&MINUTE(A1)&" minutes, "&SECOND(A1)&" seconds"

          Can you also add calculation for milliseconds as well in above?

  31. Need Excel formula for calculating the hours and minutes between to different AM and PM high tides. The two different AM (A1) and PM (B1) times could be different. The A2 could be a higher number then the B1 time number and vise versa. Need this formula for calculating this for each day of the year.

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

      =IF(A1 > A2,A2-A1+1,A2-A1)

      I hope this will help

  32. I am trying to create a spreadsheet to calculate labor pool hours in a spreadsheet when the employee is unable to clock in onsite and they are reporting IN and OUT punches. However, we use Kronos which rounds to quarter hours (example: if an employee clocks in at 8:07 am, it rounds back to 8:00 am but if they clock in at 8:08 am, it rounds forwards to 8:15 am.) If I were trying to add their IN and OUT punches to a spreadsheet and have a total time worked, is there a way to have it automatically take in to account the Quarter Rounding aspect of Kronos time to give them an accurate total time worked?

  33. I need help writting a formula that sums minutes between two specific times, for example start 9:10am - end 9:45am. I need to sum how many minutes were between 9:00am and 9:30am (20 min) and how many between 9:30 and 10:00am (15 min).

  34. I'm comparing timing for similar operations for recoding variables between R, SAS, Python and Excel. I need to calculate how long it takes, in seconds, to 3 decimal places (s.###), for a formula to calculate on an entire column in order to test the timing difference between two different formulas in Excel. Is there a way to do this? I would like to have a unique start/end time per column for when the refresh actually got to that specific column.
    e.g. for each column something like this? (untested):
    c1[=now()] d1[=now()] .... f1[=(d1-c1)*86400]
    c2[=a2*b2] ..... .... f2[=(e1-d1)*86400]
    c3[=a3*b3]
    .... ......
    Thank you for your time & reply!

  35. Hello!
    This may be simple, but I have been struggling with it. I have a report that puts out the time someone is on a call as 1:01:24 AM, when it is actually a period of time equaling 1 hour, 1 min, 24 seconds. No matter what format I put on the cell, I cannot seem to get it to change it over to the actual time period instead of the clock time of 1:01:24 AM. I am trying to do this as I would like to be able to take a list and add all of the times for the day. Can anyone help with this?

    1. Hello!
      I’m sorry but your task is not entirely clear to me. Could you please describe it in more detail?

  37. Hello,

    If we are Summing times in a "total" cell, how do you include days? So far I managed the following:
    =SUM($D$2:$D$4)&" days, "
    this got me 39.7148.... days
    but it does not breakout down into days, hours, minutes, and seconds like the interval equation or the subtraction formatting did.
    If I manipulate the format and just sum the range, instead I get like 929 hours, 9 minutes, and 21 seconds instead of it breaking it down into days.
    What I want is for the total cell to show the total times added together as something like "38 days, 17 hours, 9 minutes, 21 seconds"

    1. Hello Samantha!
      To display the total amount of time in days, hours, and minutes, use the formula

      =INT(A1)&" days "&INT(MOD(A1,INT(A1))*24)&" hours and "&MINUTE(A1)&" minutes, "&SECOND(A1)&" seconds"

  38. Hello
    I want to calculate time elapsed between 2 dates and times h:m
    then i want the result in minutes rounded up to the hour if more than 50 min

    1. Hello!
      The following formula rounds the time to an hour if the number of minutes is more than 50:

      =IF(MINUTE(A1)>50,ROUND(A1*24/1,0)*(1/24),A1)

      I hope my advice will help you solve your task.

  39. Hi how do I calculate the difference in time of my end time is going to be in a different cell each time my start time will always be in B2 for example but my end time moves depending on the amount of tasks performed.

    1. hello Steven!
      The difference between the two dates can be calculated using the DATEDIF function. Read the instructions here.

  40. I have a list of dates and times and need to total the number of entries that have the same hours:minutes (within a date). I'm having trouble comparing as with different seconds the cells are different even if the view (HH:MM) is the same and comparing the difference doesn't work if one is 8:23:45 and the next is 8:24:12 is there a way to subtract the seconds so there is always comparable minutes? The list is in ascending order.

    1. Hello Steve!
      If your data is written in column F, then you can use the formula to count duplicate hours and minutes

      =SUMPRODUCT(--(HOUR($F$2:$F$6)=HOUR($F$2)), --(MINUTE($F$2:$F$6)=MINUTE($F$2)))

      and then copy it down along the column.
      You can read about finding duplicates here.

  41. I have a timesheet and I would like to have a calculation that subtracts the end time worked from the start time worked but have it subtract 30 minutes if it is over 6 hours elapsed and also subtract 30 additional minutes if it is over 8 hours elapsed. We have part time and full time staff. There are also some full time staff who work longer hours and get an hour for lunch instead of a half hour. I have tried to modify this:
    =IF(ISERR(O28-N28),N28,MOD(O28-N28,1)-(MOD(O28-N28,1)*24>6)/48)
    which subtracts the 30 minutes but does not account for the staff that stays longer and takes an hour lunch.
    I have this
    =TEXT(O28-N28, "h:mm")-("0:30")
    but it just assumes the calculation is over 8 hours and subtracts 30 minutes.
    I am stuck. Any help would be greatly appreciated.

    1. Hello Jennifer!
      I’m sorry but your task is not entirely clear to me. For me to be able to help you better, please describe your task in more detail. What data do you want to use to change your formula? Give an example of the source data and the expected result.
      It’ll help me understand it better and find a solution for you. Thank you.

  42. Hi, I just want to simply be able to subtract times in order to get the number of hours worked. For example, in the first column is 10:00 AM (A1), in the second column is is 2:20 PM (B1). I tried doing =B1-A1 to get the total hours, but the resulting cell is showing me 4:20 AM. How do I convert this cell into an actual number of hours, and not formatted in that way?

    1. Go to the cell in question (the one that is showing you 4:20 AM) and then go to Number Format, scroll down to More Number Formats, (alternatively you can just right click, then click Format Cells), on the Number tab click TIME, under "Type" click 13:30. This will give you your answer in the format I think you want: 4:20 meaning 4 hours and 20 minutes worked.

  43. Mr. Trifuntov,
    I'm creating an excel file to manage the shifts of a restaurant and I'm having trouble to manage sums. The working shifts in most cases are divided in two (morning - evening). The columns represent the days of the week. For each worker / day I have four cells (morning (entry/exit) - evening (entry/exit). The problem arises when I don't include information in all the cells (because it is a day off/ the restaurant is close or the worker makes a continuous shift. The result in this case gives me as a result 00:00. When I want to calculate the total working hours during the week (sum) computes the 00:00 as 24 hours. What I can do to resolve this issue?.

    Many thanks in advance for your time, availability and expertise.

    1. Hello Xabier!
      To show time in a cell for more than 24 hours, set the time format to "37:30:55"
      For me to be able to help you better, please describe your task in more detail. Please specify what formula you used and what problem or error occurred. Give an example of the source data and the expected result.

  46. Hi Alex, I need to calculate the hours between two dates but excluding the holidays or weekends.Please help

  47. Hi Alexander,
    May i know what formula do i use if i want the leftover number of minutes (don't need hours) for the below scenario and what format should i set it to?

    START BREAK TIME: 13:15 (IN 24HOURS)
    END BREAK TIME: 13:30
    TOTAL TAKEN: 0:15 (MINUTES)
    LEFTOVER NUMBER OF MINUTES (IF I'M GIVEN 30MIN OF BREAK TIME): ?

    Thanks in advance :)

    1. Hello!
      To subtract time in Excel, use the usual subtraction formula =A2-A1
      You can use other methods of calculating the time difference, which are indicated in the instructions above.
      Please go to Format Cells, choose Number -> Custom Format and set
      mm:ss
      In this case, the number of minutes will not exceed 60

    2. in another words, i have recorded the break time used which is 0:15 minutes after subtracting a time from another time. i need a formula to show how much time is left if break time is given for 30 min.

      thanks again!

  48. Looking to calualte the duration between today's date and the date something was entered into my system

    i.e. created date 06/01/2019 -looking for length of time between whatever inputted date verus todays date, can some one help with the formula please?

  49. Trying to subtract one time from another ... including milliseconds and microseconds.
    Format is HH:MM:SS.mmm µµµ
    Example: 15:57:53.529 016 - 15:57:52.896 516 = 0.6325
    Any help would be most greatly 'preciated!

    1. If the time difference is negative, add 1 day (24 hours)

      =IF(B3 > B1,B1-B3+1,B1-B3)

      To the start time you need to add 1 day.
      I hope it’ll be helpful.

  50. hello. suppose i want to calculate OT hrs where staff sign in time is 9:00am and signout time is 3:00 pm. total working hrs is 6. after deducting 4 hrs which is compulsary to work, how could i find the exact time when OT starts? what will be the formula.
