Thread: PTO accrued time

I'm trying to make a table for fellow employee's to use to keep track of their PTO time. In cell B1 is the persons date started, when this is changed the other fields change along with it to show amount of time accrued. Since most people do not start on Jan 1st the amount they accrued changes during the year. If i started on 6/30/2005, I would accrue 2.16 hrs per week, but after 6/30/2010 i accrue 2.35 hrs per week. I would like the anniversary date to to be the only cell people update. After they update this cell (B1), it changes what week the amount accrued changes.
