Extended data:

First of all, the lunar calendar

In astronomy, the lunar calendar mainly refers to the calendar arranged according to the moon phase cycle, in which the moon orbits the earth once (based on the sun, the actual moon orbits more than once). ) is January, that is, the calendar based on the moon, with twelve calendar months in a year. In the process of calendar development and evolution, the emergence of 24 solar terms was used to scientifically guide agricultural production, and the lunar calendar (Han calendar) was formed. Although the lunar calendar and lunar calendar are commonly known as ancient calendar, Han calendar, summer calendar and old calendar, there are still differences between lunar calendar and lunar calendar (Han calendar). The traditional summer calendar (Han calendar) is actually a kind of yin-yang calendar.

Lunar calendar is one of the traditional calendars in China, also known as lunar calendar, ancient calendar, Han calendar, yellow calendar, summer calendar and old calendar.

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 customs, which means the first moon.

Second, the solar calendar

The solar calendar, also known as the solar calendar, is a calendar based on the movement cycle of the earth around the sun.

The Gregorian calendar year is approximately equal to the tropic year, one year 12 months. This "month" has nothing to do with the first lunar month.

The month and date of the solar calendar are very consistent with the position of the sun on the ecliptic. According to the date of the solar calendar, we can clearly see the changes of cold and warm seasons in a year. But every month, you can't see the new moon, the new moon, the new moon.

At present, the Gregorian calendar, which is commonly used in the world, is a solar calendar, with 365 days in a normal year and 366 days in a leap year, once every four years, once in a hundred years and once again in the 400th year, that is, there are 97 leap years every 400 years. 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.
