Abstract The periods of movement of celestial bodies seen by observers on the moon and their transfer relationships are called the "lunar calendar". To study the lunar calendar need first analyzes the spatial coordinate structure of the moon, put the moon in a layered, nested multilevel coordinate system, lunar observers choosing different references from different levels of coordinates will measure different rotation periods and revolution periods.Secondly, to analyze the periodicity and locality of the lunar calendar, these observers into different locations: such as the front, the back, the halo, and the lunar equator, observe the period of celestial phenomena from different positions respectively, and the conclusion can be drawn due to the different references: for example, the Earth is the best reference, the moon has no rotation relative to the Earth, but swings; refer to the sun and stars, although the lunar observer sees the similar periodic movement of the sun and stars, but is not uniform. Therefore, unlike the characteristics of the moon and the earth, the existing calendar rules on the earth cannot be copied to the moon.
