This is the list of holidays not mentioned in Torah ( from calendar I got from Kolel Shomre Hachomos of Jerusalem):
Labor Day
Columbus Day
Veterans Day
Thanksgiving Day
New Years Day (I think in Jewish calendar will be better to call it “bris anniversary”)
M.L. King Jr. Day
President’s Day
Mother’s Day
Memorial Day
Father’s Day
Independence Day
The only day missed – December’s “big day”.
If according to this calendar Jews celebrate bris anniversary, I’m wondering who’s mother and father days they celebrate.
