How do i Calculate minutes between two different dates

[Ali]

Hi Every One,
Hope some one help me out to sort out said below requirements.

I need to calculate total numbers of hours and minutes from two different
dates to calculate the %age of one week, like....Qust-1

Starting Date(A1= 10-Sept-07), Starting Time(B1=9:00), Ending
Date(C1=12-Sept-07), Ending Time(D1=9:00)----result should be 72 hrs, 4320
minutes, and weekly %age should be (24*7*60=10080 mnts in a
week)--(10080-4320)*100/10080=57.14%---if i m not worng.

Qust-2:-
Starting Date(A1= 10-Sept-07), Starting Time(B1=9:00), Ending
Date(C1=12-Sept-07), Ending Time(D1=14:00)----result should be 77 hrs, 4620
minutes, and weekly %age should be--(10080-4620)*100/10080=54.16%

Qust#3:-
Starting Date(A1= 10-Sept-07), Starting Time(B1=10:00), Ending
Date(C1=12-Sept-07), Ending Time(D1=9:10)

Waiting for Prompt reply by someone.

=((C1+D1)-(A1+B1))/7

In your examples, the first calculation is 48 hours not 72.

And the times represent USAGE, then your calculation is incorrect - why did
you subtract the usage from minutes in a week which will give "non-usage"
time?

using your figures:

% usage=4320/10080 with cell formatted as %

Hi Ali,

you have to remember that Excel counts time in day, so the solution to your
problem should be:

in E1: =(1+(C1+D1)-(A1+B1))*24 to have the number of hours;
in F1: =E1*60 to have the number of minutes;
in G1: =(24*7*60-F1)*100/(24*7*60) to have the weekly percentage.

Because, otherwise, Excel will count only two days: Excel doesn't count the
starting day.
