Although it is commonly believed that there are only 36 decans, in fact, there are around 100 decanal stars, although only 36 were used in the course of any given Egyptian year. The reason for the large number of stars has to do with the Sothic shift and the fact that the 365-day cycle of the star Sirius does not perfectly align with earth's 365.25-day solar cycle. To compensate for this minor variation, the Egyptians allowed for subtle shifts in the decanal stars they used throughout the year.

Additionally, five days were added to the end of the Egyptian Calendar each year, and these days had their own decan in addition to have a specific deity rule over each individual day.
