Where does the apostrophe go when writing about holidays?

Presidents' Day or Presidents Day? New Year's Eve or New Years Eve? No matter how hard I try to commit certain apostrophe rules to memory, I find myself re-Googling every year just to make sure I'm putting a holiday's apostrophe in the right place. 

With a slew of winter holidays having just passed or coming up, it seemed like a good time to put together a little cheat sheet of major dates with frequently misused apostrophes.

  • New Year's Eve/New Year's Day
  • Groundhog Day
  • Valentine's Day
  • Presidents' Day
  • Daylight Saving Time starts
  • St. Patrick's Day (aka St. Paddy's Day, not St. Patty's day. Here's why.)
  • April Fools' Day and April Fool's Day are both considered acceptable.
  • Mother's Day
  • Father's Day
  • Veterans Day (Though it's technically correct with or without an apostrophe, according to Grammar Girl)

(Note: It's "Happy Holidays," not "Happy Holiday's"!) Any other grammatically confusing holidays you can think of? Let us know!
