The Shugetsu Moon is about 29.530 589 days and the Star Moon is about 27.321 662 days. Their cycle is not constant and changes little by little as the years progress. The calculation formula is as follows.
|Sakumotsuki||29.530 588 853 (Sun) + 0.000 000 002 162 × Y|

On the other hand, the rotation of the earthtidalIt is also known that it is gradually decelerating due to the influence of.. There is also a theory that the difference from the revolution period of the moon will gradually decrease, and after about 50 billion years, it will agree and the earth and the moon will always face the same side... When this happens, one lunar month becomes one day, and almost half of the earth's mustard months are invisible.
