Hosting Season is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

While it's October 25th, 2024, whenever you cast your commander, create a token that's a copy of it except it isn't legendary. While it's October 26th or 27th, 2024, if one or more tokens would be created under your control, instead twice that many tokens are created and each of them enters with a +1/+1 counter on it. On any other date, both abilities apply. (Because why not?)
