I have the total number of hours and minutes between two dates and
times. but I also need to set a condition that checks whether the hours
have exceeded 24 hours.

For e.g. if 23/10/05 10:30 (Start time)
25/10/05 10:30 (End time)

Total no of hours is 47hours and 45 minutes.

I want to set a condition that will check if the hours exceed 24 hours
if so then comes with a message. I have tried IF function but it
doesnot check the minutes.

Please help

Hi,

From your example, with the start time in cell A1 and end time in cell
A2,
=A2-A1 would produce a result of 2 (or times 24 = 48 hours)
For the formula :
=IF((A2-A1)*2424,"Exceeds 24 H",(A2-A1)*24)
should do the job ...

time/date are stored as the number of days since january 1 1900.
Before the decimal point represents the number of days and therefore the
date, after the decimal point represents the time.
So simpy subtract your two date/times from each other. If 1 then that means
more than one day.
