I have a workbook with 84 sheets, one for each day. I cannot figure out how to have excel automatically increment the date in the same cell on each sheet. For example, on day one(sheet 1) I have entered the start date of 3/18/02 into C5. I am trying to figure out how to get day 2 C5 to read 3/19/02.... day 84 to read 6/10/02 with out having to enter them all in manually. Any suggestions?
