The best guess is that it tracked astrological positions, like the lunar calender and predicted events, such as the seasons.

And because the ancient Egyptians were using the lunar cycle in combination with this heliacal rising, some years ended up having 12 lunar months, while others had 13 lunar calender months, if Sirius didn't rise in the 12th month.
因为古埃及人将月球周期与这种升相结合,如果天狼星没有在第 12 个月升起, 一些年份最终有 12 个阴历月, 而其他年份有 13 个阴历月。
