The calendar associated with the new age has twelve months, each with 27 days, followed by a single day each year that marks the end of the seasons. This day is called Tenebrae. Each month is three nine-days, the days of which are Ardere, Claudere, Canere, Saltare, Congerere, Operiere, Glacies, Ventus, and Lux.
The twelve months are divided into seasons of three months each, the first and third months of each appended with Rise and End. The seasons are Sationem, Suntide, Maturam, and Withertide, meaning the twelve months, in order, are Sationem's Rise, Sationem, Sationem's End, Suntide's Rise, Suntide, Suntide's End, and so forth.
