time calculation question

[Wingzer]

Hi,

I have a question about time calculation in Excel. I have a cell that has a number of hours/minutes in it (f.e. 30:43) set as [h]:mm

Now I want to subtract 37:30 from that value. so, the result will be a 'minus time' then... is this possible in Excel?

Thanx!

Only if you use the 1904 date system (Tools > Options > Calculation tab).
