You'll want to know how to wait in Hogwarts Legacy, pretty much as soon as you pick up the game and get into the main quest. Certain quests and challenges require you arriving during either day or night, meaning you'll need to wait accordingly. It's also pretty cool waiting until nightfall to explore the Forbidden Forest in fitting eeriness, or flying around the Hogwarts' towers when their gothic style windows exude their film-like amber light.
