The differences aren't the same, they change and that is that Number I
wish to calculate/display in another Cell

With about 22 entries in between, not of the same interval.

I'd REALLY appreciate some help with this problem.

How can you subtract the times each time so you can Display the "time
interval"?

XL stores times as fractional days, so one can simply subtract the
earlier one from the later one. However, if the times span midnight, the
"later" time will actually be smaller than the earlier time (e.g., 3:00
am = 0.125, 6:00 pm = 0.75), so one needs to correct for that span. One
way:

=A22-A1 + (A22<A1)

takes advantage of XL's coercing TRUE/FALSE to 1/0.

Another:

=MOD(A22-A1,1)

Witht the times in Column B starting from B3 use:

=MOD(B4-B3,1)

and copy down using the fill handle.

It will successfully cross midnight.

If you're just trying to find time time diffrerence between consecutive
rows, then use =MOD(A3-A2,1) [as the MOD function will cope with wrapping
round at midnight]
Format the result as [mm] if you want it shown in minutes, or as [hh]:mm if
you want hours and minutes.
If you want the result available in minutes for further calculations, then
use =MOD(A3-A2,1)*24*60

Hold up a sec folks.

I noticed the only way to get a result you can read or know is to set
the cell with the answer as a TIME format..I noticed their is no way
to just get some result number like 22 or 55, it has to be some format
like 15:00:00 or 00:15:00 for 15 mins as an example.

Anyway to get a result which is just a single number?


thanks a lot.

If you want integer minutes multiply by 1440 (value*24*60) and format as
general, if you just want to change the format use a custom format of [mm]
to format 00:15:00 to 15
To get decimal hours multiply with 24 and format as general or number
