  1. Hi, I need to calculate the difference in time. I have my D&C columns formatted as "Time", and am trying the formula =MINUTE(D2-C2), but it just gives me #VALUE. Are there any other settings I need to check?

    Here is what my data looks like in each column:
    09/05/2019 3:41 PM 09/05/2019 3:57 PM

  2. in excel i am only count between 3 cell time but when I am going to + more then 3 cell time then the value gose wrong ...

  3. Hi may I ask anyone the formula to add restdays on work schedule? Thanks

  4. I am trying to have a column which shows a "-" minus sign if two times produce a minus. ie. 00:00:50 & 00:00:48 = -00:02 or if the sum was 00:00:48 & 00:00:50 = (+)00:02 but using one sum not having to individually go through & tell the formula if the sum is a plus or minus result. The first timing is 50 secs & the second 48 secs then the result is -2 seconds, etc.

  5. You have a great series of Excel lessons here.

    I’m looking at the table right above the Formula 2 heading using the formula

    =$B2-$A2

    I noticed the calculations give incorrect totals.

    Using line 3 in the table the correct number of hours should be 7 and not 6.

    I can’t even figure out where the 44 minutes came from since 15 would be the quarter hour it should be 45 minutes. But really it should still be 15 minutes since we’re subtracting 15 minutes from nothing.

    And lastly 30 seconds from 40 seconds leaves 10 seconds, where does 50 come from?

    I’m trying to setup a time sheet if the form of:

    Date In Out In Out Total

    I know that my formula will be (Out1-In1)+(Out2-In2)=Total for the Day,
    But I can’t seem to get past the incorrect calculations.

    Is there some tid-bit of information that I’m missing or just not understanding?

    Any help would be greatly appreciated.

  6. Hi can someone help me with this formula, I am calculating time on excel with this formula but times are coming out as negative figures,
    =IF(C33="","", (C33-C32)*24- C34)

  13. Dear Friends
    I want to write the calculated days.,Hours, Minutes in 00 digit format (Eg. 01 Days, 01 Hours, 01 Minutes) by using the below formula =IF(INT(B2-A2)>0, INT(B2-A2) & " days, ","") & IF(HOUR(B2-A2)>0, HOUR(B2-A2) & " hours, ","") & IF(MINUTE(B2-A2)>0, MINUTE(B2-A2) & " minutes and ","") & IF(SECOND(B2-A2)>0, SECOND(B2-A2) & " seconds","")

  14. Hi,
    I'm trying to calculate the amount of time left in a 24 hour period for multiple time slots that indicate dead time (time that is unavailable). The slots can have overlapping times. For ex. slot 1 = 8am-10am, slot 2 = 9am-11am, slot 3 = 7am-8:30am, slot 4 = 12pm-4pm, slot 5 = 1am-3am, slot 6 = 2:30 - 4:30pm. The slots do not have to be in chronological order. The result should be 24-10.5 = 13.5 left. Can anyone help?
    Thanks

  15. I want to know the formula to check whether for example 7:12pm lies between 11:45am, 12:00pm and 6:45pm, 7:30pm?

  16. Here's a simple one but sleep deprivation may be causing me to overlook the solution...

    Goal: TOTAL TIME WORKED LESS 30 MINUTE LUNCH (result cell: C1) using only cells for TIME IN, TIME OUT, AND HOURS WORKED.

    Data Format: A1,B1,C1: TIME(Hour(01):Minute(01))
    A1: IN TIME | B1: OUT TIME | C1: HOURS WORKED (LESS LUNCH)

    Data Entered (Multiple variations):
    1a. A1: 16:30 | B1: 23:00 | C1: =(B1-A1)-30 | RESULT: C1: 06:30 (0:30:00 not subtracted)
    1b. A1: 16:30 | B1: 23:00 | C1: =(B1-A1)-00:30:00 | RESULT: C1: ERROR

    Notes:
    1. entering "-30" appeared to have no effect (changing to any number produced same result - always 06:30)
    2. value in duration format '00:30:00' resulted in ERROR, adding parenthesis '(00:30:00)' had no effect, still ERROR

    Eventually, and reluctantly, I added a column for LUNCH DURATION... which worked.
    Data Format: A1,B1,D1: TIME(Hour(01):Minute(01)) | C1: DURATION(00:00:00)
    A1: IN TIME | B1: OUT TIME | C1: LUNCH DURATION | D1: HOURS WORKED (LESS LUNCH)
    A1: A1: 16:30 | B1: 23:00 | C1: 00:30:00 | D1: =(B1-A1)-C1 | RESULT: C1: 06:00

    I didn't want to have a column for LUNCH DURATION. I feel it is unnecessary. I would rather just include the LUNCH DURATION in the formula.

    How can I successfully achieve this without creating a column for LUNCH DURATION and using the column name in the formula?

  17. Plz help me in excel sheet i want total no of hours worked formula

    1. See below..

  18. I got x-numbers of objects with different timestamps during a 24h period.
    I have the total time (End time - Start time) summed up, BUT i can't count the same time twice.
    Example:
    AAA 03/07/2019 09:40-10:15, 11:30-12:00 (95 minutes)
    BBB 03/07/2019 09:40-10:20, 18:00-19:00 (100 minutes)
    But there are 20 minutes during that day that have the same time and i can't just sum that up, so the total time should be 175 minutes.
    1. How do i find the minutes that overlaps (i need to verify from the date).
    2. How do i remove the duplicates.

  29. Hi,
    I tried to used all possible formula to calculate time difference , but the return is Error
    I have used formula =$I2-$H2 or =INT(I4-H4) & " days, " & HOUR(I4-H4) & " hours, " & MINUTE(I4-H4) & " minutes and " & SECOND(I4-H4) & " seconds"
    Both gave me Error
    Here is example:
    Start Time End Time MTBF
    4/29/19 18:24:10 4/29/19 23:19:56 #VALUE! (use formula =$I2-$H2 or

    1. I think I find the answer...
      I use simple combine formula =A2+B2 , instead of formula =TEXT(A2,"m/dd/yy ")&TEXT(B2,"hh:mm:ss") , then the time difference formula =INT(D2-C2) & " days, " & HOUR(D2-C2) & " hours, " & MINUTE(D2-C2) & " minutes and " & SECOND(D2-C2) & " seconds" is working perfectly.

  36. Hi all, I'm trying to make a document calculating amount of time spent over a work-day, in different time periods. An example could be an over-all time period from 18.30 to 05.30. Cell A should define time spent between 18.00 and 21.00, Cell B define time spent between 21.00 and 00.00 and Cell C define time spent between 00.00 and 06.00. The result will be Cell A = 2,5 hours, Cell B = 3 hours and Cell C = 5,5 hours. But what formula should I use to get to the results? In advance thanks a lot! Best, Sune.

  44. Hi,
    I need to subtract minutes or hours from a given time with date change.

    Example: given time: 5:00 (am), needed time: 6 hours earlier.

  45. Hello. I have a spreadsheet with 40,000 rows of 2 columns each. StartTime and DurationInSeconds. I am trying to figure out a way to show how many of them happened at the same time. The StartTime is formatted as "mm/dd/yyyy hh:mm:ss" and the duration is just the number of seconds. I've already added a 3rd column =A1+TIME(0,0,B1) to show the StopTime so I have StartTime and StopTime. Now I need to see how many times they coincide.

  46. I need to average times for several days using military time. I have day 1=00:45, day 2=00:20, Day 3= 23:59. When I run the formula +Average(A1:A3) Excel gives me 08:21 as my answer. If I change 23:50 to 00:01 it gives me 00:22 Which is more realistic. I am averaging over a 24 hour day prior to mid-night is causing my problems. Any Ideas????

  47. Hi,
    In one cell, say (A1) I have time, and so in another cell, i applied the Formula (=A1+1). Why do i get the same time?
    What does that numeric 1 imply?

  48. Hi, I need to calculate the time between certain hours. So for example, the below shows start and end times, and I need to calculate the hours between 10am and 2pm only.
    Start time 3/12/2018 9:30:00 am
    End Time 3/12/2018 11:30:00am
    Answer 1.5 hours
    If end time was 16:00:00pm answer would be 4 hours (so, only counting time that falls between 10am and 2pm).
    Please help with a formula!

  49. hi, i need to calculate the hours reading for longer intervels ;
