Creating a view by filtering 2 columns by date (both within 3 months of today's date)

Hi all,

Trying to do a linkback from another post located here but not having much luck doing it: http://www.excelforum.com/excel-form...days-date.html

I'm working with 2 date columns and trying to filter a view to only include projects with dates within 3 months of today's date.

I've attached a current working file of the data and the end result i'm hoping to achieve via a macro of some sort.

I've manually got it to work via formula by inserting 2 additional columns (highlighted yellow) which determine if the dates "YES" fall in this 3 month time frame of "" blank if not.

Hoping to create a macro which does all of this automatically without modifying any columns if this is possible
