Mouvelian calendar

The Mouvelian Calendar is the official calendar in Tyria. It is named after Grand Patriarch Mouvel, the first high-priest of the Church of Dwayna.

The calendar counts years relative to the Exodus of the Gods, an event that took place 1072 years prior to the beginning of the game. Years Before the Exodus (BE) and After the Exodus (AE) increase the further the date is from the Exodus.
