What is the difference between the lunar calendar and the Gregorian calendar? Does the Gregorian cal

To put it simply, there are two different ways of dating. The Gregorian calendar is a chronological method in which the earth orbits the sun for one year, 365 or 366 days per year, divided into 12 months. It is now the international common dating method, and the current legal dating method in China is also the Gregorian calendar.

There will be few changes to the Gregorian calendar. The lunar calendar is based on the moon orbiting the earth as a month, and the normal year is 12 months a year, 29 or 30 days a month, 354 days a year. In order to make up for the lack of more than 365 days a year with the earth orbiting the sun, two or three years plus one month, called a leap month, becomes 13 months per year, 383 days per year.

It is a dating method created by the working people of ancient China, which is very scientific and accurate in recording climate change and the waxing and waning of the moon. After the founding of the People's Republic of China, the lunar calendar was allowed to continue as a method of chronology. As a result, the current Gregorian calendar and lunar calendar were formed.

The Gregorian calendar is also known as the solar calendar, and the summer calendar is also known as the lunar calendar (lunar calendar). Its chronology: the former is measured by the earth around the sun 360 degrees (one week); The latter is based on the 12 circles of the Moon around the Earth.

The solar and lunar calendars differ by 7 months every 19 years (lunar months). In fact, our ancestors have long mastered the basic laws of the solar and lunar calendars. The 24 solar terms are the astronomical benchmarks of the solar calendar, such as:

The winter solstice falls on December 22 every year. Therefore, we have long had experience in using the solar calendar. So since our ancestors already knew the laws of the Gregorian calendar, why use the lunar calendar?

1. Our women's menstrual cycle follows that of the moon; 2. The tidal cycle on the earth occurs according to the trajectory of the moon, and the year plus 7 months is just the ...... of the two calendars; 4. The great festival of the Chinese, the Spring Festival, is the festival of the lunar calendar.

1. The Gregorian calendar is not the same as the lunar calendar, the lunar calendar is the lunar calendar, but the lunar calendar is not only a lunar calendar. The lunar calendar that has been handed down in China since ancient times is a lunisolar calendar, including a lunar calendar recorded in the lunar cycle represented by "the full moon on August 15th" like this. It also includes the solar calendar such as "Qingming Festival", which is expressed according to the "solar terms" and always falls on April 5 every year.

Therefore, it is common to see expressions such as "the seventh day of the seventh month of the lunar calendar, the ninth day of the great heat" on the calendar, the first seventh day of the seventh month is the lunar calendar representation in the lunar calendar, and the ninth day of the great heat is the solar calendar representation in the lunar calendar.

2. Literally, the solar calendar is the abbreviation of the "solar calendar". The lunar calendar is divided into lunar and solar calendars, which is such a representation. However, since the adoption of the "Common Era" in the West, the current Gregorian calendar is basically dedicated to the "Common Era" calendar, which is also the "solar calendar".

It has to do with our habits. Because most of the dates and festivals in China are defined according to the lunar calendar in the lunar calendar. For example, "Chinese New Year's Eve" is the thirtieth day of the lunar month, and the year is the first day of the first lunar month.

The Dragon Boat Festival and so on. And it seems that there is only one "Qingming Festival" that is not a festival in the solar calendar in the lunar calendar. The solar calendar in the lunar calendar is the 24 solar terms, which are mainly for agricultural production.

The Gregorian calendar is the solar calendar, which is the universal date that is our usual date.

The lunar calendar is the lunar calendar, which is the date used for farming in ancient China, that is, the date indicated by the small print below the calendar.

2. The algorithm is different

The Gregorian calendar is a calendar based on the year in which the earth revolves around the sun. The lunar calendar is a calendar based on the lunar moon orbiting the earth for one month and 12 months for one year (13 months for leap years). (The fourth hour of the year is adjusted by leap month).
