    Calculating time formula...

    I running some tests that require me to do a couple of checks at certain points.

    Is there a formula I can use that will automatically add 90 minutes to a time that I enter into a cell? For instance, I enter 13:24 into a cell...how do I get another cell to display 14:54?

    Thanks!

    With a time in A1, use:

    =TIME(HOUR(A1),MINUTE(A1)+90,SECOND(A1))

    If 13:24 is in A1 and you want 14:54 in B1, then
    =A1 + (1.5/24)

    Time is maintained in Excel as a fraction.

    ....also

    =A1+"0:90"

    format result cell to show a time value

    What is the start time is 23:30 (is that possible) - what should the result be?
