My copy of OL2003 has Jewish holidays that go until either 5767 or 5768 in
the Jewish calendar which should push them out until 2007 or so in the
Gregorian calendar. The Jewish holidays are a seperate category from the US
holidays.

For example:
Tu B'Shevat,5763/5/15,8
Tu B'Shevat,5764/5/15,8
Tu B'Shevat,5765/5/15,8
Tu B'Shevat,5766/5/15,8
Tu B'Shevat,5767/5/15,8
Yom Kippur,5764/1/10,8
Yom Kippur,5765/1/10,8
Yom Kippur,5766/1/10,8
Yom Kippur,5767/1/10,8
Yom Kippur,5768/1/10,8
