The calendar of the Selentine Empire was originally very similar to the Emphidian calendar, with the twelve months named for the Emphidian Twelve. Following the adoption of the True Faith, the pagan names for the months fell out of favour, and were replaced with more descriptive names of common activities that take place in those months. The most common names that are used from the kingdoms of the Coradian Sea to the Island of Elles are as follows.
