Sorry I forgot to mention that this will mess up existing dates which will be
4 years and 1 day out so you may wish to consider whether using the 1904
system is for you.

I am making a spreadsheet to record employees flexible working hours.
The standard week is 37 hours and sometimes people will work less than
37 hours one week and work more the following week to make up the
difference. Therefore at the end of a week there could be a minus value
to carry forward to the following week.

I have tried to use time values but Excel will not accept time as a
minus value. I could use decimal time thus 08:30 am would be 8.50 but
I would rather use time format. Can anyone suggest a way round the
problem.

Any help/suggestions would be appreciated.
