Calendar

The calendar in Thedas consists of twelve thirty-day months. Four annums split the year, signifying the transition between seasons. A fifth annum celebrates the start of a new year. Although each month has a name in the language of Ancient Tevinter, the people of Ferelden commonly use the "low" names, shown below.
