Presidents' Day?

I have discovered that there is no such thing as Presidents' Day. Yesterday was, in fact, Washington's Birthday.

Ever since 1968, when, in one of the last gasps of Great Society reformism, holidays were rejiggered to create more three-day weekends, federal law has decreed the third Monday in February to be Washington’s Birthday. And Presidents’/’s/s Day? According to Prologue, the magazine of the National Archives, it was a local department-store promotion that went national when retailers discovered that, mysteriously, generic Presidents clear more inventory than particular ones, even the Father of His Country. Now everybody thinks it’s official, but it’s not. (Note to Fox News: could be a War on Washington’s Birthday angle here, similar to the War on Christmas. Over to you, Bill.)
