What are the leap years What are the leap years?

The Gregorian calendar generally divides the year by four divisible leap years, which cannot be ordinary years, and special years that end in 00, such as 1900, 1000, 2000, 2100, etc., which can be divisible by 100 and 400. The lunar calendar is more troublesome, basically one leap in 3 years, two leaps in 5 years, and seven leaps in 19 years, and the specific month is calculated according to the lunar calendar.

Ordinary leap year: A year that is divisible by 4 but not by 100 is an ordinary leap year. (e.g. 2004 is a leap year, 1999 is not a leap year); Century leap years:

A leap year is divisible by 400. (For example, 2000 is a leap year of the century, and 1900 is not a leap year of the century).

Leap years are created to compensate for the time difference between the number of days of the year and the actual orbital cycle of the earth caused by the man-made calendar. The year in which the time difference is made up is a leap year. There are 366 days in a leap year (31, 29, 31, 30, 31, 31, 30, 30, 31, 31, 30, 31, 30, 30, 30 and 31 from January to December).

A year divisible by 4 is a leap year, as in year. Leap years are divided into ordinary leap years and century leap years. An ordinary leap year is a year in which the Gregorian calendar year is a multiple of 4; A leap year is a year in which the Gregorian calendar year is an integer of hundreds, which must be a multiple of 400.

The intercalation rule is one leap every four years; There is no leap year in 100 years, and a leap year in 400 years.

Leap years should be familiar to everyone, leap years are the time units we think are established, in order to balance the year and the earth's revolution of an adjustment time, in leap years, our days are to have one more day than usual, so what are the years in leap years, a few years a leap year, the following by the weather network perpetual calendar channel I will answer for you.

Leap year. What are the years in leap years.

A leap year is a year with 366 days in a year, so, which years are leap years and how are leap years calculated:

1. The year from 1969 to 2032 is a leap year:

Table of leap years:

Leap Calendar:The earth rotates around the earth's axis and revolves around the sun, and the earth's rotation is 1 day, and 1 revolution around the sun is 1 year. It takes 365 days, 5 hours, 48 minutes and 46 seconds for the earth to complete one revolution.

For convenience, a year is set at 365 days, which is called a common year. In this way, there are 23 hours, 15 minutes and 4 seconds more in 4 years, which is close to 1 day, and if you add this day to February, there will be 366 days in this year, which is called a leap year.

However, every 4 years an extra 44 minutes and 56 seconds are counted, and every 400 years an extra 3 days 2:53 minutes and 20 seconds are counted, so every 400 years should be added 3 days less. It is stipulated that "there will be a leap in four years, no leap in a hundred years, and an intercalary in four hundred years."

For example, if this year is 2020 and this year happens to be a leap year, then 2100 is not a leap year, and 2400 is a leap year.

Summary. Kiss: Hello. A leap year is a leap year between 1950 and 2020.

Personally inspect the pro-defeat reputation: Hello. A leap year is a leap year between 1950 and 2020.

A leap year is a year in which February has 29 days in the Gregorian calendar, with an average of one leap year every four years.

Leap Year Table 1696, 1704, 1708, 1712, 1716, 1720, 1724, 1728, 1732, 1736, 1740, 1744, 1748, 1752, 1756, 1760, 1764, 1768, 1772, 1776, 1780, 1784, 1788, 1792, 1798, 1804, 1808, 1812, 1816, 1820, 1824, Shenmeng 1828, 1832, 1836, 1840, Kuanjie Bridge 1844, 1848, 1852, 1856, 1860, 1864, 1868, 1872, 1876, 1880, 1884, 1888, 1892, 1896, 1904, 1908, 1912, 1916, Stupid Model 1920, 1924, 1928, 1932, 1936, 1940, 1944, 1948, 1952，1956，1960，1964，1968，1972，1976，1980，1984，1988，1992，1996，2000，2004，2008，2012，2016，2020，2024，2028，2032

Calculation of leap years: An ordinary year is divisible by 4 and not divisible by 100 for leap years. (For example, 2004 is a leap year, and 1900 is not a leap year) The century macro pants year can be divisible by 400 is a leap year.

For example, 2000 is a leap year, and 1900 is not a leap year) For a year with a very poor value, if the year is divisible by 3200, and divisible by 172800 is a leap year. For example, 172800 is a leap year, and 86400 is not a leap year (because it is divisible by 3200, but not by 172800).

The Earth's orbital cycle around the Sun is 365 days, 5 hours, 48 minutes and 46 seconds (conjunctive days), which is a tropical year. The ordinary year of filial piety is only 365 days, which is shorter than the return year of the lead year, and it accumulates about one day every four years, and this day is added to the end of February (that is, February 29), so that the length of the year becomes 366 days, and this year is a leap year.

Hello, dear, it is a pleasure to serve you, "The leap year is the leap year between 1950 and 2020: 1952, Clan Defeat, Pure Bureau. Ordinary leap year:

If the Gregorian calendar year is a multiple of 4 and is not a multiple of 100, it is a leap year (such as 2004, 2020, etc. are leap years). Century leap year: The Gregorian calendar year is a whole hundred, and it must be a multiple of 400 to be a leap year (e.g., 1900 is a leap year, and 2000 is a leap year).

1. A common year is divisible by 4 and not divisible by 100 is a leap year. (e.g. 2004 is a leap year, 1901 is not a leap year).

Century years divisible by 400 are leap years. (e.g. 2000 is a leap year, 1900 is not a leap year).

For a year with a large number, it would be a leap year if it was divisible by 3200 and divisible by 172800. For example, 172800 is a leap year, and 86400 is not a leap year (because although it is divisible by 3200, it is not divisible by 172800) (this is a return year of 365 days 5h48'''Calculation).

The four divisible years are leap years, such as 2000, 2004, 2008, etc.

Kiss! Hello, leap years between 1950 and 2050.

The analysis process is as follows: 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.

Gregorian calendar years are multiples of 4 and are generally leap years. But the Gregorian calendar year is a whole hundred, and it must be a multiple of 400 to be a leap year. To determine whether a year is a leap year, the general method is to use 4 or 400 to remove the number of years in the year, if the quotient divided is an integer and there is no remainder, then the year is a leap year; If there is a remainder, then the year is a common year.

When the Gregorian calendar year is not a whole hundred, only look at the last two digits of the year number, whether it is a multiple of 4, if the last two digits of the year number are multiples of 4, the year is a leap year. When the Gregorian calendar year is a whole hundred, only look at the two digits of the number of years in the thousand and hundred, if these two digits are multiples of 4, the year is a leap year, otherwise, it is a common year.

A year that is divisible by four is a leap year. For example, 2020 is a leap year. Also, he who is divisible by one hundred is not necessarily a leap year. Therefore, there are 366 days in a year.

A leap year is a node in four years, and in this way, it is a multiple of 4, which is a leap year.

For example, the year 2020 is divisible by 4 and is therefore a leap year.

2021, not divisible by 4, not a leap year.

What years are leap years? A Gregorian year is a leap year that is divisible by four, a Gregorian year that is divisible by a thousand hundreds, and a leap year that is divisible by 400, otherwise it is not.

A year of 366 days is a leap year, and a year of 365 days is a common year.

A year divisible by 4 is a leap year.

Leap years are met: the year is divisible by 4, but not by 100 or the year is divisible by 400.
