In the U.S. and other countries, which of these is an important celebration date named for a saint?

Also st. Patricks day

This year it’s Ash Wednesday. Maybe we should put a pink heart on our forehead.

I don't have a boyfriend so I feel like I have nothing to do for Valentine's day! I do want a boyfriend but I just deny every request to be a guy's girlfriend!!

I feel awful, because I answered the question wrong.

What??? All this time I thought St. Valentine was fictional for the holiday in honor of him.
