## How to calculate hours between times after midnight in Excel?

Supposing you have a time table to record your work time, the time in Column A is the start time of today and time in Column B is the end time of the following day. Normally, if you calculate the time difference between the two times by directly minus "=B2-A2", it will not display the correct result as left screenshot shown. How could you calculate the hours between two times after midnight in Excel correctly?

Calculate hours between two times after midnight with formula

#### Calculate hours between two times after midnight with formula

To get the correct calculated result between two times over midnight, you can apply the following formula:

1. Enter this formula: =(B2-A2+(B2<A2))*24 (A2 is the earlier time, B2 is the later time, you can change them as you need) into a blank cell which beside your time data, see screenshot:

2. Then drag the fill handle to the cells that you want to fill this formula, and the time differences between two times after midnight have been calculated at once, see screenshot:

Hi All,

So I have a list of employees, all their working dates with start and end time & date.

I need to figure out how many hours were spent after midnight- night hours. The issue is that there are all sort of starting and finish times- some of the shifts were day shift the others started at 9pm till 2am, others started 10pm till next morning 5 am, etc.

Is there a way of calculating this using a generic formula for all lines?

I have tried so many variations but excel does not want to collaborate!

Hello, Timea,

Please have a try, thank you!

I only want to know the hours worked after midnight, so only the night hours.
Not total hours worked.
Hope this makes sense.

Hello, Timea
If you just need to get the hours worked after midnight, the below formula may help you：
=IF(DAYS(B2,A2)>0,(B2-A2+(B2<A2))*24,"")

Very clever, using the comparison (b2<a2) to return a boolean result so if it's after midnight it adds 1.  It took me a minute to understand what you did it was so elegant.

This doesn't work with all data. The solution I tried after trying the above was =IF(B22>C22,(C22-0)+(24-B22),C22-B22)

=IF(B22>C22,(C22-0)+(24-B22),C22-B22) is perfect but instead of ( , ) use ( ; )
thankyouverymuch

Hi, i need help please. I have data that auto loads daily at 5pm. The process is broken into 2 parts (ETL1 and ETL2). ETL1 starts at 5pm till 11pm and ETL2 starts at 11 till 4 am. at 7 am i run a script to check if everything ran. each row has a start and end date time. i would like to flag all data after 5pm yesterday as todays data. Currently when i filter on today, i only see the rows where the date is after 00:00

Can someone explain when the function of addition of the TRUE/FALSE values does so I can understand the formula please?

True = 1, False = 0

I think a simple MOD(B2-A2,1) should be enough?

This is undoubtedly the best and shortest solution.

Austin, the formula stated in the article above works well for me

The formula under bullet point #1 is wrong. =(B2-A2+(B2<A2))*24, but is should read as =B2-A2+(B2<A2)*24.

The parentheses are in the wrong spot.

THANK YOU! This is definitely the correct formula.

Yes Austin! Your formula works, the other formula renders nonsense (in my case). Thanks!!

No, Austin's correction works for me. The original with the parentheses where they are shown does not work. Maybe a diifferent version of Excel makes a difference? I am on MS Home and Office 2016

The original formula works better than your suggestion Austin.
I also used =(A2-B2+(A2<B2))*1440
This worked best to convert time into minutes.

Depois de colocar a formatação ao tentar somar a coluna total de horas o valor dá-me errado.
