There is a saying that the lunar calendar is the lunar calendar. Although the lunar calendar is called the lunar calendar, it is not a lunar calendar, but a lunar calendar. The solar calendar is the Gregorian calendar. Gregorian Calendar
The solar calendar is also called the solar calendar. It is a calendar that the sun has the final say. It is a chronology based on the period of the earth orbiting the sun. One year ≈?365.2422 days. It is a calendar based on the movement cycle of the earth around the sun. According to the date of the Gregorian calendar, the changes in cold and warmth in the four seasons of the year can be known, but it cannot show the waxing and waning of the moon, which is inconvenient for those who need to understand the tidal changes according to the moon phases. The Gregorian calendar currently used in the world is a solar calendar. It uses a solar return year as a year, and then divides it into twelve months (the number of months has 31 days, 30 days, and 29 days, all of which are artificially prescribed). It is the solar calendar, that is, the solar calendar. It is customized by Westerners and is also called Western calendar by people from Hong Kong and Taiwan. Lunar Calendar
The lunar calendar is a calendar in which the moon has the final say, and a chronological system based on the moon's orbit around the earth. One month ≈ 30.4369 days. In astronomy, it mainly refers to a calendar arranged according to the moon's lunar phase cycle, with the moon orbiting the earth once (using the sun as a reference object, the actual moon moves more than once.) It completely ignores the annual apparent motion of the sun, so it is called a lunar calendar The date cannot show the changes in temperature and temperature in the four seasons. The lunar calendar is one of the traditional Chinese calendars, also known as the "Yin calendar", "ancient calendar", Han calendar, "Huang calendar", "Xia calendar" and "Old calendar". The difference between lunar calendar and solar calendar
The so-called lunar calendar and solar calendar are two different calendar calculations, and their reference objects are selected differently.
The often mentioned lunar calendar is based on the moon as a reference. People call the time it takes for the moon to revolve around the earth as a "lunar month". The period is about 29.53 days. For the convenience of conversion, it is generally A month has 30 days and a small month has 29 days.
The solar calendar is based on the sun as a reference, and the time it takes for the earth to orbit the sun is called a "solar calendar year", which is about 365.25 days. Divided evenly into 12 months, each month is approximately 30.44 days.
Because the moon is closer to the earth, it is easier to observe. Therefore, in ancient times, the "lunar calendar" was more widely used. For example, the commonly said eight-character fortune telling, getting married, building a house, etc. were all based on the "lunar calendar".
In the folk, birthdays are basically based on the "lunar calendar". Especially in rural areas, birthdays are basically calculated according to the lunar calendar. City people prefer birthdays based on the solar calendar, but in modern times, they are not particular about it. Many, even birthdays in the lunar calendar and the solar calendar are celebrated.
The lunar calendar is certainly important, but the solar calendar is not without its merits. For example, our 24 solar terms are divided according to the solar calendar.
The earth's revolution around the sun is 360 degrees, and it is divided into 24 equal parts, each of which is 15 degrees. Therefore, every 15 degrees of the earth's revolution is a solar term.
Careful friends may have observed that compared with the solar calendar, the time of the lunar calendar is about eleven days different every year.
If calculated entirely according to the lunar calendar, we may celebrate spring in the summer within five years
