The Tak'Rahn calendar consists of 12 months of 30 days each, where each month is named after a minor deity and each day is named for one of the thirty religious spirits. Each month is further broken down into five weeks, with one week consisting of six days.

The naming of the months after the minor deities is more than just symbolic; it is claimed in religious texts that each deity has a stronger influence on Tak'Rahn during its named month and that the corresponding major deity of that alignment is also strengthened during that season.

Similar to the climate on Earth, each season lasts for 3 months with winter beginning on month 12 of each year. In Tak'Rahn a new season begins on the first day of every third month.
