# 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

=TEXT(B15,"[h]")&" Hour"&IF(OR(TEXT(B15,"[h]")+0=0,TEXT(B15,"[h]")+0>1),"s "," ")&MINUTE(B15)&" Minute"&IF(MINUTE(B15)1,"s ",""))

I need the difference between two dates/times field in hours or minutes.

Eg:

A1 B1

1/4/05 10:00 2/4/05 14:30

The result should be 13.5 hours, considering only 8 hrs per day, only business days and 8 to 5 workday.

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.

Variables:

- 'Date Received' (H11)

- 'Date Actioned.' (I11)

-'Response Time' (K11)

Constants:

Work Days = Monday to Friday

Work Hrs = 8:30 AM to 5:30 PM (no lunch break)

Public Holidays = (AC13:AC30)

Formats:

Date Received: dd/mm/yyyy hh:mm AM/PM

Date Actioned: dd/mm/yyyy hh:mm AM/PM

Response Time: d - hh:mm

If there is someone out there wiling to put me out of my missery with this one, you will have a friend for life.

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"

I have 2 dates+ times.

1 the contract start date and time.

2 the contract end date and time.

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?

Example

Start 06-Mar-07 10:00

End 14-Mar-07 14:00

This is 2 part days and over a weekend.

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.

For example

3/17/09 9:58

3/18/09 10:58

3/18/09 8:58

3/19/09 8:58

3/19/09 9:58

3/19/09 9:58

So the entries between 9 and 10 are = 3

Ideally i do not want to do text to colums and split out the parts. i would like to leave the source data alone.

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?

A1 = 07/12/2008

A2 = 02:00:00

A4 = 04:00:00

So in cell A5 i want the difference which is: "02:00:00"

but i dont know how to include the data in the formula....

etc if:

A1 = 07/12/2008

A2 = 01:00:00

A3 = 08/12/2008

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?

example attached.

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

Im trying to calculate hours and minutes between two dates/times over more than 24hrs. I have:-

A1 is 18/10/08 13:14, B1 is 20/10/2008 12:20, C1 is 1:23:05

Using the formula C1 =INT(B1-A1)&TEXT(B1-A1,":hh:mm")

But what I really need is just Hours and Minutes so the above should read 47:05.

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:

72hrs+ - return 1

48hrs-72hrs - return 2

13.5hrs-48hrs - return 3

0-13.5hrs - return 4

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.
