SO excited! One of the reasons I tend to get a little bored in the Sims 4 is I never really feel the passage of time from one day to the next despite aging. It starts feeling like the movie Groundhog Day at times when my imagination hits a lull. Although I'm super duper excited for the weather (and different weather depending on worlds, at that!), I didn't expect the calendar system and custom holidays. That's going huge for me! It will really give my sims things to plan for and look forward to (or dread) and feel like time is finally passing in a way I can internalize.
