Friends,
If I have two dates: February 5,1999 and January 4, 2002, how can I
calculate the number of months and days between both dates?
Thank you for your time.

With the first date in A1 and the second in B1
Try
=DATEDIF(A1,B1,"m")& " months "&DATEDIF(A1,B1,"md")&" Days"

For more information on the undocumented Datedif function go to
