# Calculate Time Difference Greater That 24 Hours

Aug 7, 2008
I have an excel spreadsheet where you enter the start time and end time for job function. Since some of the times cross midnight, I use the formula J3=IF(I3>H3,I3-H3,1+I3-H3) where I is the end time and H is the start time (format hh:mm). This part works fine, however when I sum column J and change my format to Time 37:38:00 (since it is over 24 hrs), it returns a large number of 2234:48:39 which should be closer to 223:00:00.

I have problem to calculate the time which is more than 23:00:00hrs in a file. I need to compare the benchmark time and the difference of time(start time and end time) and show pass/fail depending on benchmark set time. For few of the times which is more than 23:00:00 hrs the format is taking different(example: for 49:15:48, it is showing 02/01/1900 01:15:48 in formaula bar) for which i am not able to use formula and know pass/fail.

I have made a userform where I calculate how long time an operation takes. If the time fe.g. is 25 hours and 24 minutes then I get the result 1:24. I have attached my userform as it looks now. If you write 540 in the bar and 550 in volume and press "Beregn" then "Norm tid + 10%" will write 1:24 and not 25:24. Is it possible to have the Userform to write 25:24 or 1day and 1 hour and 24minutes?

I need also to calculate difference between dates(dd-mm-aaaa hh:mm) in workhours ( hh:mm):

The work period is 9-18 with lunch interval 13-14 The startdate and end date could be out of the work hours and i can't include the extra hours. I can have several days (workdays) at the difference, but i should maintain the format hh:mm.

Ex1:

Startdate 05-03-2013 18:34 ( date to calculation should be 05-03-2013 18:00)

end date 06-03-2013 10:30

Time Difference 1:30 ( from 9 to 10:30 of 06-03-2013 )

will be equal to:

Startdate 06-03-2013 8:34 ( date to calculation sould be 06-03-2013 9:00 )

end date 06-03-2013 10:30

Time Difference 1:30 ( from 9 to 10:30 of 06-03-2013 )

Ex2:

Startdate 06-03-2013 12:01

End date 06-03-2013 14:28

Time Difference 01:29

I need to enter a formula that calculates the time a report is received from the time it was recorded in our database. therefore, it needs to exclude non working hours. here are the fields:

A1 2008/10/10 16:30

B1 2008/10/11 09:30

C1 8:00

D1 17:00

A1 = report received

B1 = reported recorded in db

C1 = work day start time

D1 work day end time

Where the answer should = 2 hours.

I am not an experienced excel user and so far the only formula I have now is: =TEXT(B1-A1, "d:hh:mm")

And how do I account for weekends?

Instead of calculating a time difference manually I want to have a formula do it for me. What I want to achieve goes as followed:

08/06/2006 04:33

12/06/2006 01:05

Time difference is 92:32 [hh:mm]

another example:

09/06/2006 12:42

12/06/2006 11:35

Time difference is 70:53 [hh:mm]

So instead of getting 92:32 and 70:53 by calculating it myself I would like to have a formula do it for me. Otherwise I'll have to invest a lot of time to get the information I need.

if someone called me at 4:55pm and ended the call at 5:10pm, the whole call lasted 15 minutes. So, I want to show on excel that the call lasted 5 minutes in the 16th hour of the day (4:55pm) and 10 minutes in the 17th hour of the day (5:10pm), for a total of 15 minutes.

This may be a bit vague but here goes.

I have to calculate the difference between the start time and end time of a job. The only catch is, how can I avoid calculating "out of hours" time. So, if a job goes from 9am to 9am the next day, I want it to avoid calculating between the hours of 23:30 and 03:30.

Another example is if a job goes from 02:00 to 04:00, I want it to avoid the tim between 02:00 and 03:00.

If there is a difference in days, so the job goes overnight, how do I take that into consideration also.

I've got a time difference from 8:00AM - 12:30PM as 4.30 I'm trying to get the minutes, .30, converted into a 6 minute increment, .5. Is it possible to do this and if so how would it be done? Below is a chart of how the time is converted from 6 minutes increments into decimal form.

6 = 0.1 36 = 0.6

12 = 0.2 42 = 0.7

18 = 0.3 48 = 0.8

24 = 0.4 54 = 0.9

30 = 0.5 60 = 1.0

I am currently usins Excel 2007 and would like to calculate the diferrence in hours and minutes (ideally in decimal e.g 4:30 should be reflected as 4.5) between two date and time groups, excluding the non-working time between 17:00 and 09:00, weekends and holidays. An 8 hour working day is to be used. I have attached a spreadsheet were I tried to achieved the above with little success.

I have two Rows of data. Each row contains a unique Name column and separate columns for Date, Hour and Minute. I would like to calculate the Time difference in Days, Hours and Minutes between the two Dates. I’m not sure if the way I’ve set it up is the most practical. I’ll attach the spreadsheet to better explain.

i've two time constraints with 22:00~6:00 and 6:00~22:00. i'll apply time span to two constraints,calculate time covering on two constraints. it will start at anywhere of 00:00~24:00, time span will be 00:00 ~24:00. i add some formula, a3=start time, b3=end time. time constraints with 22:00~06:00:

=IF(AND(A3<=22/24,B3>=6/24,A3>B3),8/24,IF(AND(A3<6/24,OR(B3>22/24,AND(B3>0,B3<6/24,A3>B3))),IF(B3>=22/24,(B3-22/24)+A3-6/24,(B3+1-22/24)+MOD(6/24-A3,1)),IF(AND(OR(A3>=22/24,A3<B3,A3=0),B3<=6/24),IF(OR(A3=0,A3=1),B3,IF(A3>B3,B3+1-A3,B3-A3)),IF(AND(A3<=22/24,B3<=6/24),MOD(B3-22/24,1),IF(AND(A3>=6/24,B3<=22/24,A3<B3),0,IF(AND(A3>=22/24,B3>=6/24),(1-A3)+6/24,IF(AND(A3<=22/24,B3>22/24),B3-22/24,6/24-A3)))))))

I am setting up a time and attendance system.

What I want to do is calculate the overtime that someone has worked but in multiples of 15 minutes.

Example, if someone worked 20 minutes over they would be paid for 15 minutes overtime.

If someone worked 31 minutes over they would be paid 30 minutes overtime.

The possible overtime someone could work in one day is 6 hours.

I want it to return the overtime in decimal numbers (e.g 0.25 for 15 minutes overtime).

I have attached a sample spreadsheet.

I would prefer this to be done in VBA if possible?

I'm trying to do some calculations involving times. I'm using the format [=A2+(A1>A2)-A1] in order to calculate times from one day to the next which avoids negative numbers. This is working well. My problem is now that I'm trying to develop my spreadsheet and am trying to embed this inside an IF statement as the [value_If_True]and I get an error because it doesnt like the leading equals sign inside the IF statement.

Time arithmetic, I have two cells representing a time range.

The first one (say: X1) is formatted using the custom format [h]:mm and contains a certain number of hours and minutes. It gets its value by summing up other cells in the same format. A typical entry could be 98:35 to represent a duration 98 hours and 35 minutes.

The second cell (say: X2) is formatted as a number with 4 decimal places after the comma, and similarily gets its value by summing up other cells in the same format. It also represents a time duration as a number of hours. A typical entry could be 202.7500 to represent a duration of 202 hours and 45 minutes (because 0.75 of an hour is 45 minutes).

I would like to calculate the hour difference between these cells, and display it as hours and minutes. In the example given, the result should be negative, i.e. -104:10.

My first approach was to use the formula X1-X2 and format the result as [h]:mm, but this gives me a #VALUE! error.

I'm working in excel2007:

I want to write a generic formula to calculate the difference of time between cells, the first being a real data point, such as

6/22/2007 8:53

minus a generic constant term using the same date and a given time, 8:30.

So, what I need is something like this:

6/22/2007 8:53 – (same mm/dd/yy @ 8:30)

6/22/2007 12:29 – (same mm/dd/yy @ 8:30)

6/25/2007 11:19 – (same mm/dd/yy @ 8:30)

I have two sets of data, one is recorded every 5 minutes and the other is every 15 minutes. I am trying to add every 3 cells in the 5 minute column so I can compare it side by side with the 15 minute column. I have tried one of the responses in this forum with placing 0s in 2 cells and then the formula in the third however this does not allow me to compare the 2 sets side by side.

I need to calculate the difference between two cells that are formated like this: 11/10/2006 13:00. Simple subtract only works when the date hasn't changed (the subtract formula seems to focus on the time and ignore the date).

I found a formula that will work, but the results are in regular numbers, I need the hh:mm format and if I change the format of the result column, the time displayed is wrong.

The formula is=((B2-A2)*1440)/60)

If my result is 122.6 in regular numbers, when I convert to hh:mm I get 14:00.

Is there a better way to do this? Also, is there a way to eliminate weekend & holiday hours from the calculation? This is not as important as getting the results to calculate correctly in the hh:mm format.

Is it possible to calculate hours if both the start and end time are in the same cell. Unfortunatly the developers of our scheduling program developed it so when you export the schedule to excel it shows Greg in A1 and 3:00pm-9:00pm in A2. I would like to have excel calculate the 6 hours so I can use it to auto generate another spread sheet I am making.

i have a timesheet that we are trying to use. the problem is the column that says shift diff. if an employee works after 6:30pm for 1and 1/2hr, he is entitled to shift hours. shift hours is between 6m and 8am.

As long as he works after 6.30pm but works for at least one and a half hour, he will get the shift.

if work, 9am to 7:30pm, and have break between 2-3pm, should have 1.5hrs shift and 9.5hrs total

if work, 7:45pm-9:45pm, and have break between 8:30-9pm, total hrs work is 1.5 and shift hrs s/b 1.5hrs

if work 3pm to 12am and have break between 7-8pm, total hrs work is 8 and shift hrs s/b 5hrs

I am trying to determine the total hours of downtime accumulated when there are 2 or more machines down during the same time period. To do this, I need to be able to determine if at any point there are 2 or more pieces of equipment down at the same time, and if this is true, how many hours were overlapped. The attached spreadsheet shows how the data is presented.

I am trying to build a spreadsheet to calculate how many hours have elapsed between to entries; start time (H10) e.g. 9:15 AM and end time (I10) e.g. 12:15 PM. The formula that I am using in the calculation cell field (J10) is (I10-H10+(I10<H10))*24. This formula works great till I wish to include in an IF statement. What I would like is if the total hours calculated with the formula (I10-H10+(I10<H10))*24 is less than 4, return 4 (hours) otherwise the value. As well if there is no start time nor end time entered then return zero.

I am trying to find a way to calculate the number of hours between date/times found in separate rows. The attached data set will help to envision what I am talking about.

For each couple of rows, I need to find a way to calculate the number of hours elapsed from row 1 to row 2. In the first example, to calculate the number of hours between 12/2/2009 8:56:51 and 12/4/2009 6:35:27.
