Yes, for Jews all over the world this is Cheesecake day! The day where you’re obliged to eat Cheesecake or Blintzes, Shavuot, the festival of, uh, cheese. Wikipedia has this explanation of “the night before the Torah was given, the Jews went to sleep to be well-rested for the big day ahead. However, they failed to rise early, and Moses had to come to wake them up to meet God, Who was already waiting atop the mountain”. So they were rewarded with Cheesecake. The Jewish aspect of the monotheist’s god is a wonderfully arbitrary chap and the fact that he’ll massacre 15,000 people for saying Aaron’s a bit greedy about his clothing but doesn’t mind his entire nation sleeping in and forgetting about this book he’s written , that he’d like them to memorise and study intently every day for eternity.
