Year 2000 IS leap year even if it is divisable by 100.

CREATE FUNCTION	dbo.ufn_IsLeapYear
(
	@pDate DATETIME
)
RETURNS BIT
AS
BEGIN
	DECLARE @b BIT

	SET	@b =	CASE
				WHEN YEAR(@pDate) % 400 = 0 THEN 1
				WHEN YEAR(@pDate) % 100 = 0 THEN 0
				WHEN YEAR(@pDate) % 4 = 0 THEN 1
				ELSE 0
			END

	RETURN	@b
END
