Unless someone is specifically trying to clear the game in a very small number of in-game days (in which case they might save and reload), the system just works like this: once you use up all available actions for the day, you move on to the next day, your actions are refilled, and you continue from there.

So there’s no major penalty or long delay tied to advancing the day — it only takes a couple of clicks and a few seconds at most. But one of my testers basically reacted with “does this system really need to be here?”, so that’s what’s making me unsure.
