# Excel/Time Difference

Question
Hi Tom,

Happy New Year... I have a doubt on time.. In A1 I have date 01/01/2012 and B1 I have time as 08:21 pM (this is the time captured on that date).

On A2 date as 01/02/2012 and B2 time as 10:15 AM.

Is there any formula to check the time has crossed 24 hours or not.. Kindly help me out in this issue. Thanks.

Jayendran,

Are you asking if 24 hours have elapsed between the two date/time combinations.

then

=((A2+B2)-(A1+B1))*24

will tell  you how many hours have elapsed.   Your example gives me 13.9 hrs

If you just want to see if they are on different days, you would just check if A1<>A2  or you could subtract the dates

=if(A2-A1)>0,True,False)

if neither of those help, then clarify the question.
