As a Wiccan, we have 8 major celebrations through the year as well as quite a few minor ones, yet we do not get peacetime for those celebrations. This world (real life) is mostly a Christian based society so their holidays and celebrations are the ones that are honoured, even if most of their traditions that they got from Wiccan celebrations and rituals. On the plus side, their easter and christmas Our (northern hemisphere) Ostara and Yule are celebrated a few days before each, the southern hemisphere celebrate the opposite as it depends on the seasons. Still if this game took every religion into account, we would be in constant peacetime (maybe the real world could learn from that?!), unless this game does not recognise any religion and has no peacetime at all then everyone would be on a level playing field. But then that would mean getting rid of the events as well as no holidays would be celebrated so no need for 'special events'.
