Every few years, the lunar leap year.
Leap years occur every few years to make up for the time difference between the number of days in a year and the actual period of revolution of the earth caused by man-made calendar regulations. The year to make up the time difference, that is, the year with leap day, is a leap year. The Gregorian calendar rules for judging leap years are: leap every four years, not every hundred years, but every four hundred years. Simple calculation method of leap year in Gregorian calendar (a year that meets one of the following conditions is a leap year) 1. It is divisible by 4, but not by 100. 2. It is divisible by 400. The details are as follows: leap year refers to the year with leap day in Gregorian calendar or summer calendar. And the year when there is a leap month in the China lunar calendar. The earth's orbit around the sun is 365 days, 5 hours, 48 minutes and 46 seconds (365,438+09 days), which is the tropic of cancer. The Gregorian calendar has an average of only 365 days a year, which is about 0.2422 days shorter than the tropical year, and accumulates about one day every four years. Add this day to the end of February. This year is a leap year. According to a leap year every four years, an average of 0.0078 days will be calculated every year, and there will be about 3 more days after 400 years. So every 400 years, there will be three leap years. Therefore, the Gregorian calendar year is an integer, and it must be a multiple of 400 to be a leap year, not a multiple of 400 to be a normal year. For example, 1700. Do not leap for one hundred years, and then leap for four hundred years; Do not leap in a thousand years, and leap again in four thousand years; Don't leap in ten million years, and leap again in 500 thousand years. It should be noted that the current Gregorian calendar is adapted from julian calendar, Rome. Because we didn't realize the problem of calculating 0.0078 days per year, from 46 BC to16th century, a * * * accumulated more 10 days. Therefore, Pope Gregory XIII at that time artificially defined the date of1582 65438+10.5 as 65438+10.5, and began a new leap year regulation. Since then, the average annual length is 365.2425 days, with a deviation of about four years 1 day. The average summer calendar is only 354 days a year, more than 65438+. It is stipulated that every 30 years ends with 1 1 day, and this year has 355 days, which is a leap year. As a kind of lunar calendar, the number of days in a month depends on the monthly loss, and the time in a year is based on 12 months, which is about 1650 less than the normal year. Add one month every two to four years, and the added month is leap month. The year with leap month is 13 months, and the calendar year is 384 or 385 days. This year is also called leap year. In the 8th year BC, Julius Augustus, the nephew of Caesar, adjusted julian calendar. Julian calendar divides a year into 12 months and 365 days in a normal year. A year divisible by 4 is a leap year, ***366 days. In this way, the average length of julian calendar over the years is 365.25 days, which is 0.7078 days different from the tropical annual length of 365.2422 days, and about 3 days different in 400 years. From the implementation in julian calendar to the end of16th century, the cumulative difference was about10th day. In order to eliminate this difference, Pope Gregory (. At the same time, julian calendar's leap year rules have been modified: the year divisible by 4 is still a leap year, but for century years (such as 1600, 1700, ...), only the year divisible by 400 is a leap year. In this way, there are only 97 leap years in 400 years, three fewer than before, making the average length of the calendar year 365.500101010/also known as the Gregorian calendar. The Gregorian calendar was first used in Catholic countries and was widely used all over the world at the beginning of the 20th century, so it is also called the Gregorian calendar. China adopted the Gregorian calendar in 19 1949, but still used the year of the Republic of China. After the founding of People's Republic of China (PRC), the Gregorian calendar was adopted.

How many years does the lunar calendar run? In China Lunar New Year, a year with a leap month is called a leap year. The general year is 12 months, 354 or 355 days, and the leap year is 13 months, 383 or 384 days. As a kind of lunar calendar, the number of days in each month depends on the monthly loss, and the time of one year is based on 12 months. In order to close the earth's cycle around the sun, that is, the tropic year, one month is added every two to four years, and the added month is a leap month, so the leap year of the lunar calendar is 13 months.
There is no thirteenth month in the lunar calendar. According to the calendar rules, leap months are repeated from February to the same month after 10, and the repeated months are leap months. For example, the leap month after April is called leap April.
Calculation of leap month in lunar leap year, three-year leap, five-year leap, 19 leap; The lunar calendar basically takes 19 as a cycle, corresponding to the same time in the Gregorian calendar. For example, in the Gregorian calendar, May 27th, 2006, 5438+0, May 27th 1982 and May 27th 1963 are the fifth day of leap April.
The month of the leap month is inferred according to the laws of the lunar calendar, mainly determined according to the coincidence with the twenty-four solar terms in the agricultural season;
The number of leap months in the lunar calendar is 29 or 30 days, just like normal months.
The so-called "leap" in the lunar calendar is just called leap year and leap month, and there are also leap years in the solar calendar.
In what year does leap month occur? Leap month and leap year
If you don't pay attention, probably many people think that "leap month" and "leap year" are the same meaning, but they are not. Although there is only one word missing, the meaning is far from the same.
"Leap year", which we usually say is 365 days a year, is actually a rough figure, and the exact figure should be 365.2422 days. Then there are 365 days in a year, which is O.2422 days different from the actual year, so four years later, it is nearly one day less than the actual year. In order to make up for this difference, the calendar stipulates that four years is a leap year, that is, a year divisible by four is a leap year, and additionally stipulates that every century year (a year with two zeros at the end) must be divisible by 400 to be a leap year. For example, 1996 is a leap year, and 2000 is also a leap year, but 1700 is not. The leap year in the solar calendar has 29 days in February, the leap day is February 29 and the leap year in the solar calendar has 366 days. That is to say, February of leap year in the solar calendar is not called leap February, and leap month is unique to the lunar calendar.
