# Calculate hours, past midnight etc

C

#### CindyJ

Need help on formula calculating start time, end time, start time, end time -
with hours past midnight. What I have so far:

C3 D3 E3 F3 G3
START TIME END TIME START TIME END TIME TOTAL HRS
3:00 PM 8:00 PM 9:00 PM 12:00 AM -16.00 (should be 8
hrs worked)

or

C3 D3 E3 F3 G3
START TIME END TIME START TIME END TIME TOTAL HRS
11:00 PM 7:00 AM -16.00
(should be 8 hrs worked)

G3's formula:
=ROUND(((D3-C3)+(F3-E3))*24.2)

I've attempted to format the work times as [h]:mm but it just converts the
hours to 24 hour time (which isn't used here) - am I doing some incorrect
with that?

nothing I've found quite helps yet.

Cindy,

You need to check for the last time being earlier in the day than the third
time, and add 1 to account for that

=ROUND(((D3-C3)+(F3-E3+IF(F3<E3,1,0)))*24,2)

which can also be simplified to just

=ROUND(((D3-C3)+(F3-E3+(F3<E3)))*24,2)

You could also use the same for the first two times, in case they might be
on apposite sides of midnight as well.

=ROUND(((D3-C3 + IF(D3<C3,1,0))+(F3-E3+IF(F3<E3,1,0)))*24,2)

HTH,

Try this...

=ROUND(SUM(MOD(D3-C3,1),MOD(F3-E3,1))*24,2)

Format as General or Number

Thank you - this seems to do the trick!!
