Are seasons planned to be rolled out to stable continents?
No. They are the sole feature of Dwilight and FEI. They are not planned to be expanded to any other island. It is part of the diversity of the game.
Also, we don't really have any plans to do any kind of official calendar. Realms are free to come up with any kind of calendar they want, and to try and convince others to use it. We don't plan on forcing one.
