>>16987064The game is smart enough to know that you're changing the date. And as seasons change every month, and not every four months, in the pokemon games, one month from now your Sawsbuck will change. The reason it's locked into Spring first is because it symbolises new beginnings. Also you have to play for at least five hours every day otherwise it won't know a month has past. You also have to beat the Elite four fifteen times and Sawsbuck has to be level one hundred, your pokedex needs to be full and you need to carry three castforms on you at all times.
