Jefferson Davis’ Birthday, also known as Jefferson Davis Day, commemorates the birthday of Jefferson Davis, Confederate leader during the American Civil War and the president of the Confederacy.
So, I'm from Alabama and my dad worked for the state. While the holiday is terrible, it has a dope as hell placement.
They always put it on the first Monday in June, so it's always the week after Memorial Day.
As such, state offices basically shut down for a week, since everybody takes the Tuesday to Friday after Memorial Day off, since 4 days of leave gets you a 10 day stretch of no work.
Not saying it's good, but it'd be hella unpopular to repeal, and not cause people care about Jefferson Davis, lol.
