Hi
I need to count time in days/montht/years from one period to another.
I have tried to do a simple calkulation like 15-01-2001 minus 01-01-2000,
but problem is, that excell does not have a zero month and with some
calkulations makes plus one month. It also makes some mistakes in
calkulations of days...
Does somebody knows how to solve it?

Thank you :-)
