Difference Between Dates And Times In Days , Hours Mins ( Working Hours )

Mar 2, 2010

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 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 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 was messing around with a simple countdown timer and need a little help converting a decimal into a format of #days, #hours, #minutes and #seconds.

Cell A1 has target to countdown to 4/14/2010 12:00:00 AM Cell A2 contains =NOW() Cell A3 contains =A1-A2 with the result being 69.4021441 with the amount of decimal places varying depending on when it is refreshed.

I'd Like the result in A3 to read something like "There are 69 days, XX hours, XX minutes and XX seconds until event"

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 have a data feed that gives a column of cells formated mm/dd/yy hh:mm These are call entries, what i want to do is count all the occurances each hour, so count all the entries say between 9am and 10am. However the column is very long and holds data for many weeks so i want to be able to ignore the date part of the cell.

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 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.

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.

1) The output of an excel duration is : 22.00:8.00:25.00 ( day:hour:minutes ) - excel cannot average and work with this number format

2) resolution - =(LEFT(L2,4))+MID(L2, FIND(":",L2)+1,4)/24+MID(L2, FIND(":",L2,7)+1,4)/1440 as an array and Custom Format the cell as [h]:mm - works perfectly.

Q: to be conistent, the initial reporting is dd:hh:mm and then I convert to hh:mm so that excel can process the data. How can I convert from hh:mm to dd:hh:mm so that the excel report can be consistent in presenting the data to senior management?

I have a downtime tracking spreadsheet that we want to be able to track the downtime on the line. However, we only want to count the working hours, not overnight, etc. I have added the weekend day work hours and Saturday work hours but haven't been able to figure out how to connect them into a formula with the down time.

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 have a spreadsheet with various date fields and next to those time fields. I need to calculate the amount of working hours between the 2 lots of values

for example

Cell A has "22/02/2008" Cell B has "16:44:00" Cell J has "25/02/2008" Cell K has "08:59:00"

The answer i'm looking for is 01:29:00. The working hours are Monday to Friday 07:30 - 16:00. This is what I have so far and it gives me the total hours between the 2 dates but not the working hours. =IF(J10-A10=0,K10-B10,((J10-A10)+(K10-B10))) (Formatted with [h]:mm:ss). I have tried using workingday() but can't get the desired result

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 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'm trying to calculate shift working hours without using dates.

The scenario is

Cell A1 = Start Time Cell A2 = Start Time Cell A3 = Break Time

Basically I want the output to calculate hours worked between:-

0000 and 0600 as a total in cell A4 0600 and 1800 as a total in cell A5 1800 and 0000 as a total in cell A6

Then if the value of A5 is greater than A3, subtract A3, but if the value of A5 is less than the value of A3, A5 should be zero and the remainder of the value of A3 subtracted from A4 (or A6) depending which has a value.

How should I calculate working hours between two dates? Say if start at 26 july at 15:00 and finish at 29 july at 10:00, the function should return 4 hours because the working hours are from 8am to 5pm (8 - 17), and there is a weekend between the dates. Preferably the function should work like the NETWORKDAYS() function, but it should also include the time, not just the dates. And also, if have to add say 8 hours to a date, how should I calculate the result? Also this function should aware of the working hours and holidays, so it should ignore those times.

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.

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 have an entire column with numbers such as 48, 95, 30 etc representing hours. how do i format cell so that these numbers will show, 2days, 3days-23hrs-45mins, 1day-6hrs

Thought it would be easy enough to just right click and format the cell but doesn't seem to have the option *shrugs*.

How should I calculate working hours between two dates? Say if start at 9/25/2009 7:26:13 PM and finish at 10/20/2009 9:46:13 AM, the function should return 245:20:00 because the working hours are from 8am to 11 PM (8 - 23), and there are weekends between the dates. Preferably the function should work like the NETWORKDAYS() function, but it should also include the time, not just the dates.
