To get the night shift hours (18:00 - 06:00)

With start time in A1 and end time in B1
06:00 in A2 and 18:00 in B2

to get the night shift hours

=MAX(0,MIN(B1,A2)-IF(B1A1,A1,MIN(0,A1-A2)))+MAX(0,1-MAX(B2,A1)-IF(B1A1,1-B
1,MIN(0,B2-B1)))

to get the day shift hours

=MOD(B1-A1,1)-(MAX(0,MIN(B1,A2)-IF(B1A1,A1,MIN(0,A1-A2)))+MAX(0,1-MAX(B2,A1
)-IF(B1A1,1-B1,MIN(0,B2-B1))))

i I am working on a spreadsheet, where I need to know how to Calculate
between two time formats, i.e. I want the cell to calculate between 06:00
and
18:00 and 18:00 and 06:00. If some one starts work at say 17:00 and
finished
at 07:00 the following day, I need it to tell me how may hours before
18:00,
then how many hours between 18:00 and 06:00, the how many hours after
06:00.
If some one could help.

Thanks John
