Regarding your example, I don't think the result for 30 months is 11/1/08. It should be 7/1/2009.

Another way:

In cell A1: 1/1/07

For 3 months: =EDATE(A1,3)
For 30 months: =EDATE(A1,30)

Like Bernard said format cell ......

If EDATE function is not available, and returns the #NAME? error, install and load the Analysis ToolPak add-in.
