Is the lunar calendar Zhouyi?
Calendar based on the apparent movement of the sun, referred to as "solar calendar" or "solar calendar"; The moon is "lunar calendar", and the calendar made according to the apparent motion law of the moon is called "lunar calendar" for short.
The lunar calendar determines the moon according to the law of its movement: the orbit of the moon is called the white road, and both the white road and the ecliptic are two great circles on the celestial body, which intersect at five degrees and nine minutes. The moon goes around the earth and appears on the ecliptic twice, which lasts for 7 hours and 43 minutes 1 1.5 seconds on the 27th, and is called "Stellar Moon". Only when the moon revolves around the earth, the position of the earth also changes. The forward count is more than 27 degrees, and the moon runs 13 degrees 15 minutes every day, so it takes 12: 44: 2.8 to return to the moon on the 29th, which is called "the first moon", and it is called the moon according to custom, which means the first moon.
