The below formulae allows me to see the difference between two dates and only returns the difference in working hours ie : Difference between 02/02/2010 08:00 & 03/02/2010 08:00 is 16 Hours 0 Minutes

=(INT(A3)-INT(C6))+MAX(MOD(A3,1)-MAX(MOD(C6,1)))

The following displays it in the Hrs and Mins format

I need to calculate the difference between a start time and end time in hours and minutes.

Start 01/07/2008 11:40

End 01/08/2008 19:28

Start and End columns are formatted as 'Custom' m/d/yyyy h:mm.

I'm not sure what formula to write to calculate the hours and minutes between the two times. Everything I've tried doesn't count over 24 hours. Also what do I format the result cell as?

I have call data in date/time 06/07/08 2:00 PM custom format for a 2 month period. I have my regular opening times eg Monday 9-3, Tuesday 10-4. For each call I want to know if it was made during opening times or not.

I am having difficulty finding the difference between two times and dates in Excel. I have researched this on Google and tried several formulas but none have worked for me. The format the data is currently in can be seen below:

I want to display the difference in C1 in a format along the lines of "dd hh:mm". The data for seconds and fractions of a second is included in the source data but is not needed in the final results.

If the date and time falls on the same day, I have no trouble doing a simple "B3-A3" to determine the answer. For example:

From the below example, I would need to know the difference between date & time of Received and Resolved in number of days. Meaning - time difference should also be calculated in days

CELL ACELL BCELL CCELL DCELL E - REQUIRED OUTPUTReceived DateReceived TimeResolved DateResolved TimeTurn Around Time - IN DAYS20-Jan-122:43:00 PM23-Jan-124:50:00 PMDifference between Resolved date & time and Received date & time

I have two rows of data (A & D) which I would like to determine the amout of time spent for each issue. The value in both column appears as DD/MMM/YY HH:MM:SS. I am looking for a formula to obtain the below result.

I have a spreadsheet with Received Date/Time in C2 and Resolved Date/Tim in D2, Work Start Time in E2, Work End Time in F2. C2 and D2 are in dd/mm/yyyy hh:mm AM/PM format:04/03/2008 10:27 AM06/03/2008 1:06 PM9:00:00 AM5:00:00 PM

I need to be able to calculate the resolution time of each request in hours/mins excluding weekends and public holidays. I've tried using the NETWORKDAYS function but it doesn't seem to pick up multiple days between the Received and Resolved dates/times. I have put the Public Holidays in my spreadsheet ( attached) in AA2-AG2.

I receive data from a company I deal with that has the date and time of all of my transactions with them listed in an excel worksheet. Only problem is that the date/time that I receive is not in my timezone, which is a bit of a problem for me!

What I want to do is to be able to adjust the date and time shown in the cell forward by 14 hours, so that the data is shown in the timezone that I am currently in. So the end result for the first line of data in the attached file would end up being 2006-08-11,10:28:51 instead of 2006-08-10,20:28:51.

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 can’t figure out why this formula is not working. I am trying to alter it a little, but I still think it should work. Here is what I am trying to do. I am looking to calculate the time difference between two work projects, but exclude time when the office is closed. So someone starts a project at 2pm and finish 10am the next day it will show a result of 4 hours because the office closes at 5.

Here is the formula. It is the time formula from cpearson.com ...

I need to create a spreadsheet that will calculate the difference between two dates and show the result in days. The complicated part is that weekends (Sat and Sun) need to be ignored and any time after 4:30 pm needs to be treated as the next business day. I have been trying to look at similar questions in forum and use the WORKDAYS function with little success.

Example:

A1- 14/08/09 4:40 p.m. B1- 17/08/09 9:10 a.m.

I need the answer (B1-A1) to show up as 0. But if the time in A1 was changed to 4:20 p.m. than the answer should be 1 day.

I need to calculate billable hours.I have a start date/time and end date/time.Then I need to subtract out all time between 05:00:00.000 and 20:00:00.000. These are not billable hours.But I can include all weekend time.And I can include all holiday time.I need to accomplish this with formulas, no macros.

I am creating a 'HelpDesk Issue Logger' and I am trying to calculate the Network Days and Network Hours between two dates with times. I want to know how many business days and hours are between the two days to give me a TURE 'Response Time.'

I have been to several sites and forums looking for the answer, but I have not been able to find a solutions that works for me. Please find attached a 'stripped' down version of my project.

I need to calculate the hrs between two date and time and deduct any time outwith the hrs of operation (09:00-19:00), if the date and time falls outwith these times. I have used the formula 24*IF(A2>G2,G2+1-A2,G2-A2), where G2 IS 21/04/2008 11:45 and A2 is 20/04/2008 00:22, but can't get it right.

I have a spreadsheet used for calculating information based on the dates specific shifts are requested/cancelled by our clients. I have a formula for working out if a date & time of cancellation is less than 48hrs notice of the shift starting. This is because we have cancellation fees based on this.

What I have is this formula: =IF(A16="","",IF(INT(A16)-INT(G16)<2,1,"")) that returns a 1 if that shift is cancelled within 48hrs notice. This works fine but I have to now change the notice periods to the following:

edit this formula to take this into account? I figure it's using multiple IF's and changing the <2 into something else like the number of hours but I'm not sure of the exact syntax.

Can I calculate the number of working hours between these two using a formula? So if I have a 10 hour working day (08:00-18:00), Mon-Fri and the two Dates/Times can I calculate the number of working hours?

I'm looking for a formula that will calculate the difference in times between specific times while working with a 24 hr clock. Please see details below:

E3 provides the start time of 4:00 H3 provides an end time of 15:30

If an employee works betwen the hours of 0:00 (midnight) to 5:59, this is considered DIFF hours and is therefore the number I am seaking. So for the data noted above, the total DIFF hours worked is 2 hours.

A1 is 10 (10 hrs worked) , A2 is 10:30am (in time), A3 is 9:00pm (out time), A4 needs to be the total hours and minutes between A2 and A3 based on the hours listed in A-1. What i need is a formula that will calculate the hours and minutes between the 2 times based on hours entered in A1 but that will also compensate for a manadatory 30 minute lunch that needs to be deducted from the total hours if hrs listed in A1 are more than 6.

example: worked 10HRS, 10:30am to 9:00pm, Total hrs is 10hrs 30min, which should be just 10 since the lunch is a none work time and must be subtracted.

If a person worked more than 6hrs, they must take a lunch. if they worked less, than 6 then they don't have to. I need a calcuation to recognize the greater than, less than factor into the equasion also.

I have a client who weants to work out the total number of hours (not minutes) between two times. I have managed to do that with no problem using the formula =IF(A2>B2,B2-A2+1,A2+B2). However, this is where the problem starts.

They want to multiply the number of hours with the number of men on the job, but the answer is wrong, and I cannot understand why. I have checked the formnat of the cell and changed it to see if that is the problem, but without success.

I have copied it below

Time inTime outNo hoursNo of MenTotal Man Hours 12:0003:001526 14:0018:00474

I'm trying to calculate the number of hours an agent works between the hours of 7AM and 7PM. Column B has their START time, Column C has their END time, Column D includes their LUNCH time, and Column E calculates the total number of hours worked (=IFERROR(SUM(C248-B248)-D248,"-").

I've created 3 additional columns (Column F = number of hours before 7:00, Column G = number of hours after 19:00, and Column H = Total excluded hours which represents the total number of hours an agent worked before 7AM or after 7PM.

I've attemped several different formulas, but they all give me '#########' in one cell or another.

I have a form for weather warnings that has time of issue in cell B19, and the time of occurrence in cell D19, and the times are in a 24hr military style time format (1600, or 1735, etc).

I need cell G19 to tell me the time difference between the two in hours and minutes, but here's the catch - if cell B19 has an earlier time, I need it to display the difference as a positive number, indicating that I issued the warning before the event actually occurred. If D19 is earlier, I need it to display in cell G19 as a negative number, indicating that the event occurred before I had a chance to issue the warning.

I have a column that finds the difference between two times and I have it formatted as h:mm so that I get results such as 0:55 for 55 minutes. The problem is that when I try to get an average, median, and sum for all the times in that column it doesn't work. It comes up way short. I'm assuming it has somthing to do with the formatting.

I am trying to calculate the difference between a scheduled start time and an actual start time. If the actual start time is greater than the scheduled start time a negative time (hh:mm:ss) should be returned. instead the cell is populated with #############....

I have tried to reformat using the custom formats, but the only options in excel 97 are for either standard numerics or £ (these return a minus figure).

I've had a look at the time functions but could not see a suitable one.

I'm sure there is a simple format solution to this.

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 to work out the time difference between 2 times over a 24 hour period. There is a fixed booked departure time and an actual time of departure, the actual time of departure can be either before or after the booked time. I need the time difference between the times shown as either +/- minutes at present it returns the time in [HH:MM]. I have a simple IF formula to work out - time but when it calculate + time it returns the reverse difference.
