Re: National Freedom Day?

While changing the month on a recycled calendar (2014), my eye chanced
to light on February 1, marked "National Freedom Day, USA". What? Never
heard of it.

  I've got this collection of calendar dates here, and I keep
  stumbling across these off-the-wall commemorative days and
  giving them the cold shoulder (though I'm not always sure if
  they're as out there in their home turf). For instance:

MMDD
0104 National Trivia Day
0116 National Nothing Day
0120 Reindeer Day
0123 National Handwriting Day
0126 Australia Day
0206 New Zealand Day
. . .
0915 Felt Hat Day, when men of fashion put away their straw hats.
. . .

  , and let's not forget:

0402 Doris Day (1924)

  . /Tomorrow/ however, is a real day: It's Groundhog day!
