A lot of these holidays have great pasts or history. I don't appreciate the commercialization of them and most of the today's people have forgotten the history of them.
Flag Day for us in the United States is a day in June to celebrate our Flag. The adoption of our flag, which it also happens to be the Army's celebrated birthday. It is not an official day, but we wanted a day of celebration in June.
Arbor Day started back in the 1800's, just an improvement day... then in the 1960/70's we got EARTH DAY....(pointless).
April Fools Day long history there.... back to Medieval times
Grandparents Day, Parents Day, Sweetest Day are new days made up to have a second chance to show your love you love them. I like sweetest day better than Valentines Day, but that's me.
Ground Hog Day- when some little (actually quite large) rodent comes out of his burrow and if he sees his Shadow 6 more weeks of winter or 6 more weeks til spring. UM, duh, it is always 6 more weeks til Spring....
POINTLESS
St. Patricks Day - I'm of Irish Protestant heritage, me celebrating a Catholic holiday is nuts, I don't wear green and if someone comes up and pinches me they are going to get punched. But I understand the background of this holiday... and as an Irishman, who doesn't like a day to drink.
Labor Day - the creation of the Labor movement and is dedicated to Social and economic achievements of the American Worker. Supposed to be a national Tribute for all the workers have done, "strength, prosperity and so on.... " sounds like a Union holiday to me.
