We're talking, of course, about Anniversary Day, which dates back to the latter part of the 19th Century. Celebrated on the first Thursday of June, which is this week, the day originally began as a celebration of Protestant Sunday Schools, but grew into a full-fledged public holiday in the in the 1950s, giving kids in Queens and Brooklyn – that's right, kids in the other three boroughs still had class – the day off from school.
It's a tradition that has largely fallen by the wayside. Although kids still get the day off from school, there are no longer the large parades and celebrations that once marked the day.
If you get a chance, do your part to help bring back a little part of history that belongs only to Brooklyn and Queens.
