I need a formula that calculates the end date of each calendar quater based
on the year. For example, if the year in A1 = 2009 then the dates in A2
through A5 should be 1/31/09, 4/30/09, 7/31/09 & 10/31/09 respectively.
When
I change A1 to 2010, I need the dates to reflect 2010 dates. I would also
need the formulat to account for leap years if possible.

Thank you
