I am a Christian, however I do not feel that a Christmas event meshes with the lore. Likewise, I do not believe that any other existing holy day(s) would work. If they implement a seasonal event, it should work within the lore. Perhaps a Festival of Life or Rebirth? Instead of looking to have an event for your religion or my religion, why not seek to be inclusive? Why not express our generosity, kindness, and desire to unify peacefully instead of making it just about one holiday over the other? Edit: I'm glad that you personally feel the same way as I do, and am sad that many other individuals want it to be all about them.
