The difference between lunar calendar and lunar calendar

The differences between the lunar calendar and the lunar calendar are as follows

1, different years

China lunar calendar adopts the appropriate principle of "placing leap", so that the approximate length of the average calendar year is equal to the length of the tropic year (365.2422 days).

Therefore, the lunar year and the solar year are basically synchronized, but the lunar year is only a simple accumulation of 12 lunar months, with a length of 29.5 × 12 = 354 days, which is about 165438+ with the solar year. Therefore, after the accumulation of length, there will be an inversion between the month and the cold and heat. The Lunar New Year is usually in winter, but it may come in summer.

2, the use of different regions

China lunar calendar is widely used in China and Southeast Asia, because it can reflect the exchange of cold and summer and the change of moon phases, so it is widely used in the mid-latitude areas of the northern hemisphere, especially in the national conditions of China.

The use of the lunar calendar is mainly limited to Islamic countries, and it is only used when celebrating religious festivals.

3. Different functions

The lunar calendar in China has some characteristics of the solar calendar, which can be used to guide agricultural time and arrange crop rotation.

The lunar calendar can only reflect the change of the moon phase, but not the change of temperature, so it is a pure "lunar calendar" and cannot guide agricultural activities.
