Posterized: Movies named after holidays

With Mother's Day in theaters today starring romcom queens of yester-yore (Kate Hudson, Julia Roberts and Jennifer Aniston) the question comes to mind: What other U.S. holidays are available for Garry Marshall to make all star ensemble mosaics about?  A lot of holidays are already taken as you'll see in today's Posterized. (Disclaimer: We've opted to include only movies with theatrical releases and no holiday-themed titles -- there'd be hundreds with straight to dvd titles or movies with a holiday within the title)

How many of these movies, which take their names from holidays, have you seen?
Let's take them in order of their place on the calendar.

New Year's Day (1989), New Year's Day (2000), Groundhog Day (1993)

Ash Wednesday (1973), Valentine's Day (2010), April Fool's Day (1986)

Mother's Day (2016), Independence Day (1983), Independence Day (1996)

Labor Day (2013), Halloween (1978), Halloween (2007)

Christmas Eve (1947), Christmas Eve (2015), New Year's Eve (2011)

Still waiting for the Garry Marshall Treatment: Columbus Day, Martin Luther King Jr Day, Flag Day, President's Day, Easter, Father's Day, Thanksgiving... although the latter did get that sick sick sick fake slasher trailer by Eli Roth in Grindhouse (2007)

It seems beyond strange that the best movie named after a holiday is still a low budget 1970s slasher movie (that turned out great and became highly influential, for better...and usually worse). Halloween was #3 in our list of greatest modern horror movies.
