Presidents Day

I am a fan of Alexandra Meeks Banner, a woman often listed as writer of CNN Five Things AM.  She has a way of explaining what happened fully, succinctly and respectfully. She wrote this morning that

Depending on the state, it may be known as Presidents' Day, President's Day or Presidents Day — a subtle shift in apostrophe placement that has fueled decades of debate.

I take the simple plural without really knowing what my state is doing.

Despite having read that and liking it consciously, I went to the bank today.  Guess what I found.  The place was closed!  Because it is Presidents Day!
