Try this:

=ROUND((D2-C2)*96,0)/96*24

Or, if the times might span past midnight:

C2 = 7:00 PM
D2 = 1:00 AM

=ROUND(MOD(D2-C2,1)*96,0)/96*24

Format as General or Number

Trying to calculate time and round to nearest 15 minutes.

Example:

C2 11:46 AM
D2 4:30 PM

E2=D2-C2 this gives me hours and minutes format of 4:44

I would like the result to be rounded to the nearest 15 minutes in decimal
format. (not rounded up or down each time, but to the nearest 15 minute
interval)

In this example I would like the result to be 4.75

Any help is appreciated.

Thank you
