I have 3 time cards on Sheet 1. 1 time card contains total hours for every
work day in April and May. On the other hand the other 2 time cards only
have total hours for every work day in May.

I totaled the hours for each day and linked them to cells in Sheet 2. Now I
want to filter Sheet 2 so that it only gives me the hours for the Month of
May. I would like to set up the workbook the same way for June, July,
August, etc. Do you have any ideas about how I might accomplish that?
