I don’t get why exactly the calendar needs to change? Because the seasons don’t line up any more? I suppose over thousands of years the expectation when winter is happening will have moved as well. Or is it because days and years won’t match with other planets? That’s not something a calendar can fix.
Maybe someone can help me out here: I was going to watch this with my wife. She has seen Wandavision, but she skipped some of the newer shows. Is there any sign yet that you should’ve watched any of them before?
