Calculate Future Date?

Hi guys,
Could you advise a formula to calculate a date added with 1.5 years?
Example:

Column A:
January 1, 2011

Result should be:
Column B
June 1, 2012

Something like that.
thanks in advance.

You marked this solved... is it?

If not, then try:

=EDATE(A1,18)

this gives date 18 months after A1 (i.e. July 1, 2012).. if you want the prior month then:

=EDATE(A1,17)

Note: EDATE is an analysis toolpak addin function (Tools|Addins|Analysis Toolpak)
