Is there an easy way to start with a date, say 7/11/2001, and then write a calculation for the next date in line, taking into account that different months have more or less days? My plan at this point is to write a series of If/Thens using Month([date]) and then attaching the correct number of days to the result, so if the starting date is 7/11/2001, my If/thens would see that it is July, need to add 31 days, so next date would become 8/11/2001. Klunky. Any easier way? Thanks, SLH
