Who can clearly tell me the difference between the lunar calendar, the solar calendar, and the lunar calendar?

The lunar calendar uses the moon to orbit the earth once (with the sun as the reference object, the actual moon moves more than once) as one month, that is, the synodic month is used as the basis for determining the calendar month, and a year is divided into twelve calendar months a calendar.

The calendar set based on the apparent motion of the sun is called the "solar calendar", or "solar calendar" for short; the moon is the "lunar calendar", and the calendar set based on the apparent motion of the moon is called the "solar calendar". "Lunar calendar", referred to as "lunar calendar".

The lunar calendar determines the moon based on the movement rules of the moon: the orbit of the moon is called the ecliptic. The ecliptic and the ecliptic are both two great circles on the celestial body, intersecting obliquely at five degrees and nine minutes. The moon orbits the earth. One week, the zodiac appears twice, for twenty-seven days, seven hours, forty-three minutes, eleven and a half seconds, which is the time it takes for the moon to make one revolution, which is called a "sidereal month". Only when the moon orbits the earth, the earth's position also changes due to its revolution, advancing more than 27 degrees, and the moon travels 13 degrees and fifteen minutes every day, so the moon self-conjuncts, completes a full circle around the earth, and returns to the new moon. The synodic moon actually takes 12:44:2.8 on the 29th, which is called the "lunar lunar month". According to custom, a month refers to the lunar lunar month.

The solar calendar, also known as the Gregorian calendar, is a calendar based on the movement cycle of the earth's revolution around the sun. The calendar year of the solar calendar is approximately equal to the tropical year, and there are 12 months in a year. This "month" actually has nothing to do with the synodic month. The months and dates of the Gregorian calendar are in good agreement with the position of the sun on the ecliptic. According to the dates of the Gregorian calendar, the changes in cold and warmth in the four seasons can be clearly seen in a year; but in each month, the moon's new moon cannot be seen. , Wang, two strings.

The Gregorian calendar currently used in the world is a solar calendar, with 365 days in an ordinary year and 366 days in a leap year. There is a leap every four years. There is one less leap every 100 years. There will be another leap every 400 years, that is, every 400 years. There are 97 leap years in the year. The average length of the Gregorian calendar year differs from the tropical year by only 26 seconds, and it would take 3,300 years to accumulate just one day.

A Chinese calendar is a lunisolar calendar, generally called the lunar calendar. There are twelve months in an ordinary year, the big month has thirty days, the small month has twenty-nine days, and the whole year has 354 or 355 days (which month is bigger and which is smaller in a year varies from year to year). Since the number of days in each year is about eleven days less than that in a solar year, seven leap months are set up in nineteen years. The year with a leap month has 383 or 384 days in the year. According to the position of the sun, a solar year is divided into twenty-four solar terms to facilitate agricultural planting and other activities. The chronology is based on the combination of heavenly stems and earthly branches, and the sixty-year cycle begins again and again. This calendar is said to have been created in the Xia Dynasty, so it is also called the Xia calendar. Also called the old calendar.

The Arabic numerals on our current calendar are the Gregorian calendar, which is the solar calendar.

As for the month of the month, it is the lunar calendar or the lunisolar calendar.
