If the desk or wall calendar that you refer to throughout the year is one you purchased or was given to you as a gift then you may not be aware that May is National Military Appreciation Month. In addition to my National Audubon Society wall calendar, I have two others, both from organizations that support USA's military veterans. As a thank you for donations, the Veterans of Foreign Wars (VFW) and Paralyzed Veterans of America (PVA) mail out notepads, note cards, pens and calendars. I've asked them not to spend their hard gained money on mailing these to me, but they either don't receive my mail or pretend like they don't because all the above keep on coming every year. No complaint here. If I relied solely on my "civilians" calendar I wouldn't know that May allows opportunities to raise our flag four times: one is for Mother's Day (the 14th this year), and the other three are to recognize those who have honored our country with their service.
15th~~~Peace Officers Memorial Day - the flag is to be flown at half mast until sunset. (on this same day in 1942 the Women's Army Corps was founded) This day pays tribute to the local, state, and Federal peace officers who have died, or who have been disabled, in the line of duty. President John F. Kennedy signed the Congressional bill into law on October 1, 1962.
29th~~~ Memorial Day - flag is to be flown half mast until noon
In addition to the above, my VFW calendar for the month of May shows four non-flag-flying days of recognition:
7th~~~ Unconditional surrender of all German forces signed in 1945
8th~~~ V-E Day (Victory in Europe Day) Declared in 1945
12th~~~ Military Spouses Day - President Ronald Regan set this one in motion in 1984. It's always celebrated on the Friday before Mother's Day
22nd~~~ National Maritime Day - this day in May was chosen in recognition of when the American steamship Savannah set sail from Savannah, Georgia in 1819. This was the first ever transoceanic voyage under steam power. The United States Congress created this holiday in 1933.
(the 22nd is also Victoria Day in Canada - to honor/honour Queen Victoria's birthday)
Scurvy Awareness Day - which is today, May 2 (I am not making this up; someone else did). Tomorrow, the 3rd is Hug Your Cat Day and two days later is Cinco de Mayo, which if I'm not mistaken means while drinking tequila you must have five shots of it. No? Seems appropriate. If you don't like it straight you can add it to some OJ and pat yourself on the back for being health conscious and doing what you can to keep your body scurvy-free.
Here's another serious one which in some circles certainly warrants a flag raising; to honor America's first female astronaut, the 26th of May is Sally Ride Day.
Two Different Colored Shoes Day
Do you have any May days of celebration to add, either real or would be fun/silly/bizarre?
