I need to identify whether a date range contains a leap year day - 2/29. I
have a start date and end date and leap year True/False indicator
Start Date 01/01/08 01/01/08 03/31/08 06/30/07
End Date 12/31/08 06/30/08 12/31/08 03/01/08
Leap Year? TRUE TRUE FALSE TRUE
I can say that the range must be (will be) less than or equal to 365/366.
Thanks!
Slight error. Formula should be:
=SUMPRODUCT((MONTH(ROW(INDIRECT(StartDate&":"&EndD ate)))=2)*
(DAY(ROW(INDIRECT(StartDate&":"&EndDate)))=29))0
The SUMPRODUCT function returns the number of Feb 29's from StartDate to
EndDate inclusive.
