My university implemented a plan to celebrate different religious holidays every year starting in the 1960s. Well they started by giving Jewish holidays off and never ended up changing it until 50 years later where they have now eliminated all religious days off. They will still consider them an excused absence for the purposes of tests and whatnot but the whole university is no longer closed.
Also the gym I go to is the Jewish Community Center which closes early today and is shutdown Thursday and Friday. Lame.
