Different but related concept! Moratorium weeks are institutional blocks of time (standard in college, depending on the academic schedule/seriousness for highschool) where you're not allowed to engage with your sport - no coaching, no practice, etc. Generally these are for things like finals/midterms. You see them most commonly talked about in american football because of it's popularity, but it's a thing in pretty much any college sport. My institution has extended them to even include the HvZ and League of Legends games.
