What's the difference between the lunar calendar and the yellow calendar?

The earth goes around the sun for 365 days, 9 minutes and 9 seconds, and it takes 4 minutes, 08 seconds and 46 seconds from the vernal equinox to the vernal equinox, which is called a year in a year. The vernal equinox is gradually westward, so although it is actually shorter than the Sunday of the earth, with a difference of 20 minutes 13 seconds, it is precession, from the first day of the first month to the first day of the first month of the following year, which is called year. The lunar month is headed by the day when the sun and the moon meet each other, and the second meeting is about 29 and a half days apart. Therefore, the number of days in a month is either 29 or 30. Because the laws of months are different, the years are different. In a year, the number of months can't be odd zero, but it is only 354 days, which is about 1 1 day different from the actual year. This is probably the lunar calendar. The ecliptic, also known as the ecliptic, is a term in astronomy. It means that the earth revolves around the sun once a year, and the circular route of the sun between celestial stars, that is, the trajectory seen on the earth in a year, will turn 360 degrees. People divide it into 12 equal parts, 30 degrees per minute. In the past, because of superstition, people believed that there were good days, so they had to turn over the zodiac calendar to see which day was the auspicious day of the zodiac, and the old calendar would be established. Except for the words "full, flat, broken, closed, open and closed", each date in the calendar is marked with 12, and the day corresponding to the words "broken, broken and closed" is an auspicious day of the zodiac.
