Kara-Turan calendar

The Kara-Tur calendar was the calendar by which the civilized lands of Kara-Tur measured the months of the year.

History
The modern calendar was devised by an emperor of Shou Lung in ancient times, in order to fix the dates of various annual festivals and holidays. In this, it was very successful and was widely adopted by all the civilized cultures of Kara-Tur by the mid–14th century DR.

Months
The calendar was arranged according to the movements of the Moon and the constellations in the Celestial Heavens, which were maintained and steered by the Moon Women. The standard calendar comprised twelve months, four with 29 years and eight with 30 days, with a total of 356 days in a year. The months, their numbers of days, and the events held during them are as follows:
 * Tsou (30 days): New Year's Festival; holy day of the God of Heaven; Feast of Lanterns; holy day of the God of Spring; holy day of the God of Wealth; Fertility Festival; holy day of the God of Happiness, holy day of the God of Learning.

Events
The calendar included many special feasts, festivals, and holidays celebrated by the many cultures of Kara-Tur. Feasts were causes to gather in numbers and enjoy a grand banquet, or at least an affordable one. Festivals were celebrations that could run for several days, and even weeks. Holy days were dedicated to one or more gods; whether or not they were observed in a community depended on its culture and dominant faith. Where they were observed, they were simple affairs, and were typically a reason for a feast.

Years
The years sometimes had names: Shou Year 2607 (1357 DR) was known as the Year of the Great Sky Serpent, and Shou Year 581 (−669 DR) was known as the year of the Ding Hai.
