couting consequetive months

[Tom]

I'ce got a sheet with begin week (colomn A) and end week (colomn B) going
back a number of years. How do I add the cumalative months in colomn C?

=DATEDIF(A1,B1,"m")
this will give you the difference between the 2 dates in whole months.

"DATEDIF" excellent thanks, i changed it a little to:
=DATEDIF($A$1,B2,"m")
to get the differance from the row before making a cummulative value.
Thanks for lead.
