I liked having Lincoln's Birthday - February 12
I liked having Washington's Birthday - February 22
In school, we talked about the men - we drew log cabins for Abe and Cherry Pies for George - and they became the symbols and memory triggers for the many things we learned
I always thought (and still do) that, additionally, we needed a Founder's Day.
Now we have this day that no one knows anything about
except that Federal (and some State) Employees get off.
President's Day = a day to celebrate one specific President (which one?)
Presidents' Day = a day to celebrate many specific Presidents (which ones?)
Presidents Day = a day of many Presidents (all of them?)
So now, no one celebrates anything - no one learns anything -
no one knows anything about the Presidents.
