What is the leap month of the year? This year it is a leap month

2022 has passed, and a brand new 2023 has arrived. According to astronomical science experts, 2023 is a common year in the Gregorian calendar, with 28 days in February and a total of 365 days in the year. The upcoming lunar year is a leap year, with a total of 384 days in the year.

Zhao Zhiheng, a member of the Chinese Astronomical Society and a director of the Tianjin Astronomical Society, introduced that the Gregorian calendar and the lunar calendar have different historical origins and calendar systems. The Gregorian calendar has a leap year every 4 years. Normally, a leap year is a leap year in which the number of Gregorian years can be divided by 4, and February has 29 days; Except for the endless years, there are only ordinary years, and February has 28 days.

The year 2023 cannot be divisible by 4, so it is a normal year with a total of 365 days.

The lunar calendar is based on the cycle of the moon's full and short changes, a synodic month is a month, about a day, and the whole year is generally 354 days or 355 days, which is 11 days less than the 365 days or 366 days of the Gregorian calendar year (also known as the return year and the solar year).

In order to make the length of the lunar year similar to the length of the Gregorian calendar year, the ancients adopted the method of adding leap months, that is, adding 7 leap months to the 19 lunar years; There are 13 months in a leap month, and the year is generally 384 or 385 days, called a leap year. In this way, the 19 lunar years and the 19 Gregorian calendar years are almost equal in length.

As for the specific month in which the leap month is placed, it is related to the "middle air" of the 24 solar terms. The 24 solar terms are composed of 12 solar terms and 12 middle terms, the beginning of the month is called "solar terms", and the middle of the month is called "middle energy", and the two are arranged alternately. The rule for adding a leap month is that in each month, everything that contains a medium gas is counted as a normal month, and those that do not contain a medium air are counted as the leap month of the previous month.

The "leap February" of the Year of the Rabbit in the lunar calendar does not have a mid-season, so it is the leap month of February of the previous month.

The reporter saw on the astronomical calendar that due to the arrangement of a "leap February", the Year of the Rabbit in the lunar calendar has a total of 384 days, starting on January 22, 2023 and ending on February 9, 2024.

This year it is a leap monthA: This year, 2023, is a leap February.

Leap years are generally leap months as follows: 1968 leap July, 1976 leap August, 1984 leap October, 2004 leap February, 2012 leap April, 2020 leap April, 2028 leap May, 2036 leap June, 2044 leap July, 2052 leap August, 2080 leap March, 2088 leap April, 2096 Yan April. These are all leap years with leap years, which we also call double leap years.

A leapmonth is a calendar in which leap is placed. In Asia, especially in China, a leap month refers to a month that increases every two to three years in the lunar calendar. In order to reconcile the contradiction between the return year and the lunar year, and prevent the disconnection between the lunar year and the return year, that is, the four seasons, one leap is placed every 2 3 years.

In ancient times, the leap week of seven leaps in 19 years was adopted, and the fixed leap week was abolished in the "Lin De Calendar" of the Tang Dynasty, and the intercalary month without a season was adopted, so the leap time was intercalated.

Leap years and leap months can be divided into:

A leap year in the Gregorian calendar refers to a year with a leap day in the Gregorian calendar or summer calendar, which can be divided into an ordinary leap year and a century leap year, an ordinary leap year means that the Gregorian calendar year is divisible by 4 but not by 100, and a century leap year is a Gregorian year that is divisible by 400 (e.g., 2000 is a leap year of the century, and 1900 is not a leap year of the century).

Leap year is set up to make up for the time difference between the number of days of the year and the actual orbital cycle of the earth caused by the provisions of the artificial calendar, and the year that makes up the time difference is called a leap year, which has a total of 366 days, and the number of days from January to December are 31 days, 29 days, 31 days, 30 days, 31 days, 31 days, 30 days, 31 days, 30 days, 31 days, 30 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 days, 31 A leap month is a month in a leap year that has an extra day, i.e. February, which has 29 days.

The leap month in China's lunar calendar is a way to put the leap in the calendar, because it stipulates that the big month is 30 days, the small month is 29 days, so that the year is nearly 11 days worse than the Gregorian calendar, therefore, if the year after the end of a month, the number of days that are extra before is just enough for a month, it will be increased by one month, so that the average length of the lunar year is very close to the Gregorian calendar, the increased month is called a leap month, and the year with a leap month is called a leap year. <>

Leap month, lunar calendar to the moon.

The calendar around the earth is about 10 days and 21 hours apart from the 365 days of the return year at 5 hours 48 minutes and 46 seconds each year, and the intercalary is accumulated, so there should be a leap month every three years, two months every five years, and seven months every nineteen years. In this way, the month added to each leap year is called a leap month. A leap month is added after a certain month.

It's called a leap month.

Leap month, leap year.

In order to adjust the average length of the calendar year to match the length of the return year, it is sometimes necessary to adjust the length of individual months or to increase the number of months in the year. This adjusted or additional month is called a "leap month".

The leap month calendar method was first invented and used in China, about 500 years BC, than ancient Greece.

More than 160 years earlier. The Chinese calendar adopts the method of seven leap months in 19 years, which is different in different periods and countries.

In the traditional lunisolar calendar in China.

New moon in China and Israel. The length of the day is the average of 1 month.

In the 12 months of the year, the difference between the length of the day and the return year is about 10 days and 21 o'clock, and it is necessary to place an intercalation to make the lunisolar calendar months and celestial phenology.

Maintain the corresponding relationship. In China's ancient six calendars, the leap month method of 3 years and 1 month, 5 years and 2 months, and 19 years and 7 months of leap month is used, and the month added in each leap year is called "leap month". For example, the Qin Dynasty and the early Western Han Dynasty used the "Zhuan Xiang Calendar", which starts with October and takes September as the end of the year, and the leap month is placed after September, which is called "post-September".

At the beginning of the Western Han Dynasty, it was formulated at the beginning of the Taichu.

For a long time, the leap month was divided into the months of the year, and it was stipulated that the months without the middle air were used as the leap months, and the monthly order was still used as the monthly order of the previous month, as long as it was called "leap month". This rule of intercalation is most reasonable in the use of a flat calendar. In the Qing Dynasty, the calendar was changed to a fixed qi calendar, and if the rule of not placing a leap in the center was continued, it was possible to place two leap months in a year.

Therefore, it is added that a leap year is defined as a leap year in which there are 13 months between the two winter solstices, and that the first month of a leap year without a neutral air is designated as a leap month. This rule is still in use today.

Leap years are intercalary.

April, May, and June are the most, and leap.

September and October are the least, and leap November, December, and New Year do not occur, at least for thousands of years.

In the Gregorian calendar, a leap month is not an additional month in a year, but an additional day in a certain month to ensure that the calendar year coincides with the return year. For example, the Julian calendar.

The current Gregorian calendar generally has 365 days in a year. The month of February is usually added by one day every four years (sometimes eight years apart in the current Gregorian calendar), making the year 366 days. February of this year is a leap month, and this year is also called a leap year.

Last year there was no leap month.

You're talking about a lunar leap month. Last year there was no leap month, this year it is a leap February. Leap months are generally run once every three or two years, and two of the five years are leap years. The last leap month was in 2020, running April. Runnian has:

Leap April 2012, Leap September 2014, Leap Six Chain Month 2017, Leap April 2020, Leap February 2023.

Leap June in 2025, Leap May in 2028, Leap March in 2031, Leap Winter Moon in 2033, Leap June in 2036.

Leap May in 2039, Leap February in 2042, Leap July in 2044, Leap May in 2047, Leap March in 2050.

Leap August 2052, Leap June 2055, Leap April 2058, Leap March 2061, Leap July 2063.

Leap May 2066, Leap April 2069, Leap August 2071, Leap June 2074, Leap April 2077.

How leap months are calculated.

A leap in three years, a good wheel, 7 leaps in 19 years.

Determine the date by the phases of the moon: calculate the date and time of the conjunction of the sun and the moon one by one, and know that the first day of the month is the date of the conjunction, if the interval from this conjunction to the next conjunction is 30 days, then the current month is the big moon; If you only take your grandson every 29 days, it will be a small month.

Determine the order of the month by the middle of the month: Distinguish the calendar month and the leap month by whether there is a middle air in the calendar month, a return year has 12 middle terms, but it contains a synodic month, after several calendar month rotations, there must be a calendar month without a middle air.

Last year's leap months were related to February, because there were 29 days in February in leap years, only 28 in non-leap years, and 4 years were a leap year.

Leap years between 1950 and 2050:

The analysis process is as follows:

The year 1952 is a general year, 1952 4=488, 1952 is divisible by 4, so 1952 is a leap year.

The year 1956 is a general year, 1956 4=489, 1956 is divisible by 4, so 1956 is a leap year.

1960 is a general year, 1960 4=490, 1960 is divisible by 4, so 1960 is a leap year.

1964 is a general year, 1964 4=491, 1964 is divisible by 4, so 1964 is a leap year.

1968 is a general year, 1968 4=492, 1968 is divisible by 4, so 1968 is a leap year.

Table of leap months in the lunar calendar from 1949 to 2020 AD.

1949 Leap July 1952 Leap May 1955 Leap March 1957 Leap August 1960 Leap June.

1963 Leap April 1966 Leap March 1968 Leap July 1971 Leap May 1974 Leap April.

1976 Leap August 1979 Leap June 1982 Leap April 1984 Leap October 1987 Leap June.

1990 Leap May 1993 Leap Defeat March 1995 Leap August 1998 Leap May 2001 Leap April.

2004 Leap February 2006 Leap July 2009 Leap May 2012 Leap April 2014 Leap September.

2017 Leap June 2020 Leap April.

As can be seen from the above table, leap four, May and June are particularly abundant, leap nine and October are particularly rare, especially without crude lead there are leap eleven and twelve.

Month and New Year. Why is that? It turns out that the time interval between the two middle gases is not the same. Previously mentioned.

Days are just averages. In fact, the Earth's orbit around the Sun is an ellipse, and the Sun is located on one of the ellipses.

on focus. The farthest point in orbit from the Sun is called "aphelion", and the closest point is called "perihelion". The earth is far away.

If the movement near the day point is slow, the time interval between the two zhongqi is long, and the longest reaches the day, so there is no possibility of zhongqi.

The more, the more opportunities there are for leap months. On the contrary, if the earth moves fast near perihelion, the time interval between the two mesogases is shorter, and the shortest is only more than 29 days, so there are fewer chances of not containing the mid-gas, and there are fewer chances of leap months occurring. In this way, it would not be surprising that there is no leap month for the first month or the lunar month.

If there is a leap month, it should be placed in the first month or.
