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!
