How to distinguish between lunar calendar and lunar calendar?

The lunar calendar is the lunar calendar.

The lunar calendar is the lunar calendar and the solar calendar is the Gregorian calendar. On the calendar, Arabic numerals indicate the date of the solar calendar and Chinese characters indicate the date of the lunar calendar. The solar calendar goes fast, but the lunar calendar goes slow. For example, 65438+19 Gregorian calendar/0/0/day is called New Year's Day, which is also called Gregorian calendar year. At this time, the 26th of the lunar calendar 1 1 has just arrived.

The calendar legally used in People's Republic of China (PRC) is Gregorian calendar, which is common in most countries in the world. So the date of birth on the ID card is the solar calendar, and the date of birth certificate issued by the hospital is also the solar calendar. All legally binding documents are certified by the solar calendar. In other words, the date of birth is the date of the month, not the date of the lunar calendar.

Return to solar calendar

Accordingly, the direct point of the sun changes periodically. In 2000, 365 days, 5 hours, 48 minutes, 45. 19 seconds (or 365.438+0897 days) was designated as the year of returning to the motherland, and the calendar was called "Returning to the solar calendar".

When observing the changes of stars on celestial bodies during the earth's revolution around the sun, we will find that there are periodic changes between the sun and the zodiac signs. According to this periodic change of the position of the sun in the ecliptic, the year 2000 is 365 days, 6 hours, 9 minutes and 9.76 seconds (or 365 days and 004 days), which is regarded as a sidereal year, and the calendar is called "solar calendar".
