The lunar calendar determines the moon according to the motion law of the moon ball: the orbit of the moon is called the white road, and both the white road and the ecliptic road are two great circles on the celestial body, which intersect at five degrees and nine minutes. The moon went around the earth once and appeared on the ecliptic twice, lasting 27 days, 7 hours and 43 minutes 1 1.5 seconds (27.32 days). How long does it take for the moon to make one revolution? Xingyue? . Only when the moon revolves around the earth, the position of the earth will change because of its revolution around the sun. The forward count exceeds 27 degrees, and the moon runs at the speed of 13 degrees 15 minutes every day, so it takes 29 days 12: 44 minutes and 2.8 seconds (29.53 days) for the moon to orbit the earth once.

The average length of the Gregorian calendar is only 26 seconds away from the tropic year, and it takes only one day to accumulate 3300 years.
