Hi all,

I have a logbook spreadsheet with hours logged in time format and the total
calculated in the third column formatted [h],mm, If I specify sunset in a
time format can I get the night hours in a seperate column?
cheers
 
If I understand you correctly and assuming that you have - say - sunset in
B2 and sunrise in C2 the:

=MOD(C2-B2,1)

will give you the hours of darkness.

Thanks Sandy I'll try that,
what I have is this in columns
16:30 (time out)
21:30 (time in)
5:00 (total time)

now if say sunset is at 1930 what want is another column
2:00 (night)

hope that makes more sense.
