I've already commented I think, but feel like I need to say, with this new developments:

The calendar sounds amazing, and it's going to be amazing to have a solid gameplay item that shows the passing of time as well as the feeling you get from the seasons. If it's as amazing as I think it will be (and I am cautiously optimistic that it will be) it's going to completely change the way I play the game and add a layer of realism. Usually, I plan vacations/parties/weddings on a whim when I realise that the majority of my Sims will be off work. Now I can actually plan it in advance.
