Sixteen Days of Caïs

suggested pronunciation /'kais/. In western astronomy and calendrics, there is the principle of the Sixteen Days of Caïs. Typically, the Asdaran year has 384 days which is sixteen short of the number four hundred. According to legend, ancient astronomer-priests believed that a mysterious sorcerer of godlike power, Caïs, left the realm of mortals and returned shortly the same day only to discover from his underlings that he had been gone for sixteen days. The ancient astronomer-priests also reasoned that because of this, it is necessary to add sixteen intercalary days over a period of a 'great year', a cycle of about twenty eight thousand years.
