The holiday is Washington’s Birthday. It had been a national holiday before Congress moved most holidays to Mondays. Nixon came up with the idea of calling it “Presidents Day,” probably thinking that Lincoln was also supposed to be honored, but Lincoln’s birthday had never been a national holiday.
He may have but it was not a prevalent thing until the ‘90s.
Actually in MD it seemed to be pretty settled that it was “President’s Day”. I was shocked and pleased in the ‘90s when moving to CT that my work had Washington’s Birthday. But then, the very next year it went to President’s Day.
First, not overly pleased deliberately celebrating Lincoln. 2nd, the very generic name has already given 5e idea we’re just celebrating any ol’president. Which makes us have to get into Uhbama and libs have to do Trump. LOL.
