# Calculating Date & Time Difference: Result In Hours Only

Sep 29, 2006
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.

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?

I want to find the hours worked in day shift and night shift. Day shift is from 06:30 to 18:30 and night shift is from 18:30 to 06:30. Listed below is an example of my date/times.

Note that the night shift carries over to the next day.

Start/Finish

21/12/09 07:00 to21/12/09 11:09

21/12/09 07:46 to21/12/09 14:41

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'm calculating the difference in time:

9:54-9:45 = 0:09

Now to convert this in minutes (in number format), I multiply this number with 1440:

0:09*1440 = 9

When I click the cell this number is actually 9.0000005, rather than exact 9. I need it to be exact 9 since I have to match this number from other excel sheet.

To sum up:

This is what I expect:

31.99999 should be changed to 32

10.000001 should be changed to 10.

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've got a spreadsheet of samples taken at certain time intervals for a period of 2.5 hours, they were collected in hh:mm:ss format. Most of them are approximately 5 minutes apart. What I'd like to do is convert the first time to 00:00:00 and then recalculate each sample from there. Is there an easy way to do this?

So, what looks like this right now:

8:45:00

8:45:36

8:50:36

8:55:36

9:00:36

Would look like this:

00:00:00

00:00:36

00:05:36

00:10:36

00:15:36

etc...

I'm trying to calculate the available man hours I have for my shift/team. I have got the basic formula to deduct the time, and lost time for breaks ok, but when the shift end time crosses midnight the formula returns a "value" error message. i.e. start time = 18:00. End time = 24:00 breaks = 15 mins gives me a formula like this =TEXT(O17-N17-P17,"h:mm") and a result of 5:45

How I can make this formula work so it can calculate the variance even though the shift ends at 02:00am the following morning?

I manage a team in a call centre and deal with lots of reports on excel.

I am dealing with a report on a daily basis that i need to use in order to calculate the total idle time that each of agents have. There are roughly 170 agents.

After I have formatted the cells to hh:mm:ss, the obvious thing to do would be : =(B1-A1)

Is there a way to write a macro (or anything) in order to reapply this to the report on a daily basis? Bearing in mind that this has to be done daily for 170 individual reports. They work a 8am - 5pm shift. So there is an entry every time they make a call.

Agent Name

Extension

Initiateddate

TerminatedDate

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.

I am conducting some analysis on alarm data of certain devices and am looking for creating a VBA algorithm that will do the following (refer to the table below for example data)

I want identify an asset in alarm (Column F) and based on its asset ID (Column C) and Fault Description (Column D) then find the row when the asset with the same asset ID and fault description returns to an 'ok' Asset State. After the row where the same asset ID and Fault description is found where the asset state returns to 'ok', I want to calculate the total alarm time based on the difference between when the asset ID and Fault description goes from 'Alarm' State to 'OK' state from DateandTime Column.

I want the result to be populated in a new worksheet that displays data with the following column headings as a result of the above calculations: Date, Asset ID, Asset Description, Fault Description, Alarm Time

I have added an additional column to show the type of output I am after.

There are up to 20,000 rows of data I want to perform the above calculation on.

C

D

I want to make a formula based on 2 times ex: 10:07:00 and 10:09:00. This formula should display "intime" if the diference between both is under 20 minutes, "outime" if the diference is above 20 minutes and it should display "error" if the time is under 0 minutes (this will only happen when someone makes a mistake typing in the time. For example 10:37:00 and 10:36:00)

I am using the following formula in Column E to calculate the difference between an employees start time, and their previous shift end time in order to work out how many hours rest they have had:

=IF(A4=0,"",IF(I4=0,"",MOD(I4-B4,1)))

My Current Formula works fine for same day calculations, but if an employee finishes work at 18:00 on Friday and starts work at 22:00 Saturday night, Excel calculates the Total Rest hours as 04:00, when in fact they have had 28:00 hours rest...

Is there a way of calculating the hours difference between two dates?

I have attached a sample of my spreadsheet to illustrate

I can't figure out how to do a proper formula for calculating time. For instance I have one column that says "Time In", the next is "Time Out" and the other is "Lunch Time". My calculation needs to be this:

Find the total hours between the Time In and Time Out and then Minus the lunch time to get total hours worked for the day. The only way I can get this to work is using 24 Hour time format. Is there another way?

I’m working on a timesheet and I need to separate the hours worked that are before 6 am from all the others. For example if someone works 1:00 am to 8:00 am I need a cell to populated with 5 representing the hours worked before 6 am. The formula below works fine except when the start time is 12:00 am. I am also having trouble if the start time is before midnight like in a 11pm to 5 am shift.

=(IF(AND(S3<=$AG$97,S3>=$AG$73),(($AG$97-S3))*24,0))

S3 is the start time

AG97 is 6:00 am

AG73 is 12:00 am

I am trying to figure out a difference in hours between date & times.

Cell & Info:

A1 = 07/12/2008

A2 = 02:00:00

A3 = 07/12/2008

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

A4 = 01:00:00

A5 should be = "24:00:00"..

I am looking for a formula to calculate time from one date and time to another. The only catch is I only want it to use times during specific times.

Example

Start 5/1 8am and end 5/2 8am. The working hours are from 7am until 4pm and from 8pm till 5am. In this example the solution should be 17 hours.

How do I set up a formula to respect only working hours (also excluding weekends except for Saturday early am from midnight until 5am.

Sorry if this is confusing, I am trying to use IF statements but I’m fighting a losing battle.

I am using Microsoft Excel 2003. My question is about calculating time. Let's say my answer, after calculating time, is 2 hours and 1 minute (2:01) and that answer is placed in cell A1. How would I be able to have only the 2 hours (2:00) carry over to cell A2 without the minutes showing?

I have tried =MOD(A1,24/24) and =TIME(0,HOUR(A1),0). I have also tried to right click the cell, went to Format Cell, went to the Numbers tab and tried the different options in the Time and Customs category, but I can't seem to get 2:01 to appear as 2:00 only.

We have a person who work in 24/7 support. One person work passive 24 hour, but it 24 hours are divided in to next shifts: normal 06-18, over hours 18-22, night hours 22-06.So if we have some one who is supporting client say from 17h till 23h, we have next results:

Name Start time End Time 06:00 - 18:00 18:00 - 22:00 22:00 - 06:00

John 17:00 23:00 1:00 4:00 1:00

Is it possible to in time range enter formula who subtracted end time from start time, but taking into account 24 hours?

If a Rescue Officer is called out at 23:00 and is back at 04:00, this should equate to 5 hours worked.

It seems that if my times are all on one side or the other of a 24 hour cycle, my calculation work fine but it it breaks across the 24 hour (as above, it doesn't work.

A2=04:00

A1=23:00

Using (A2-A1)*24 give me -19.00 hours

My SS macro has a line:

s = (wks.Cells(c, 3) - wks.Cells(c, 2)) * 24 'calculates the duration of time worked

Is there any way of getting excel to calculate an elapsed time in hours when the start and end times roll over from one day to the next?

The below is for Excel 2003.

I want to set up a spreadsheet that can show my work is completed within a service level agreement, based on working hours of 9-5 Monday-Saturday.

I want to be able, for example, to log that a piece of work is reported at 09:00 on a Monday and completed at 10:00 on Monday and for excel to calculate that as 1 hour until completion. Fine so far. But what if that job was closed at 10:00 two days later? Based on an 8 hour working day, that should be 17 hours.

And what if a bit of work comes in at 17:00 on the Saturday. No one works the Sunday. Say the job is completed at 10:00 on the Monday. that should calculate as 1 hour to completion.

The SLA I'm setting is 4 hours.

I use datediff to calculate the difference between 2 dates in Months.

Result = Datediff("M", Date1,Date2)

I need the result to be formatted to 2 decimal places ie 23.52 (months)

Not neccessary to use datediff if this doesnt work.

Please note I have cross posted this HERE because I couldnt get connected to ozgrid for some reason, I will montior both sites for a solution and post back results. Apologies for the inconvenience.

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 want to add hours to a date-time cell to get result in date-time.

Format of cell A1 is d/m/yy h:mm AM/PM

Format of cell A2 is General

Format of cell A3 is d/m/yy h:mm AM/PM

I want to add A2 (number of hours) to A1 to give A3.

The formula I used is A3=A1+Time(A2,0,0)

The formula works perfectly fine when A2 is less than 24, but when A2 is more than 24, the date doesn't get changed.

I have 2 cells with dd/mm/yy h:mm format. I have been using =TEXT(BQ3-BP3,"[h]:mm") to work out the hours and minutes difference between the 2 cells. However I would like the formula to work so that the hours and minutes difference will only come into effect after midnight on the first day. For example

01/01/06 23:30 - 01/01/06 23:45 would read 00:00

but

01/01/06 23:30 - 01/02/06 00:45 would read 00:45
