The leap year of the Gregorian calendar is stipulated as follows: the earth's revolution around the sun is called a return year, and the return year is 365 days, 5 hours, 48 minutes and 46 seconds. The Gregorian calendar stipulates that there are common years and leap years, and there are 365 days in a common year, which are shorter than the return year, and there are a total of short days in four years, so one day is added every four years, and there are 366 days in this year, which is a leap year.

There are 365 days in a normal year and 366 days in a leap year.

Common Era years are divisible by 4 as leap years, but the number of years in a whole hundred (0 in the single and tenth places) must be divisible by 400 to be a leap year. Everything else is an ordinary year. February in leap years has 29 days.

A year in which there is no leap day in the solar calendar or no leap month in the lunar calendar is called a common year. The solar calendar has 365 days in a normal year, 354 or 355 days in a lunar ordinary year, and in rare cases 353 days.

A leap year was established to compensate for the 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.

Leap years include years that have leap days in the Gregorian (Gregorian) or summer calendars.

Leap years have 366 days.

A common year generally refers to a year in which there are no leap days in the solar calendar, or there are no leap months in the lunar calendar; The second refers to the year when the crop harvest is very ordinary. Divide the non-whole hundred years by 4, or the whole hundred years by 400, if not divisible, it is a common year. February in a common year has only 28 days, a normal year in the Gregorian calendar is 365 days, a common year in the lunar calendar is generally 354 days or 355 days, and in rare cases it is 353 days.

Leap Year Calculation Method:

1. Non-whole 100 years: those that are divisible by 4 are leap years, such as 2004 is a leap year, and 2001 is not a leap year.

2. Whole 100 years: 400 divisible is a leap year, such as 2000 is a leap year, 1900 is not a leap year.

3. For a year with a large value: if the year is divisible by 3200 and divisible by 172800, it is a leap year.

Leap years have 366 days. There are 365 days in a normal year.

Ordinary year: 365 days in a normal year, the number of years in the Common Era (not a hundred) is not divisible by 4 for a common year; However, the number of years in the whole hundred (0 digits and 0 digits), which is not divisible by 400, is also a common year.

Leap year: 366 days in a leap year (31, 29, 31, 30, 31, 31, 31, 31, 31, 31, 30, 31, 30, 30, 31, 30, 31 and 31 in January and December).

Calculation method:

1. Ordinary years that are not divisible by 4 are ordinary years. (e.g. 1901 is a normal year, 2004 is not a normal year).

2. Century years that are not divisible by 400 are common years. (e.g., 1900 is a normal year, 2000 is not a normal year).

3. Non-integer centennial: divisible by 4 is a leap year. (e.g. 2004 is a leap year, 2001 is not a leap year).

4. Whole 100 years: 400 divisible is a leap year. (e.g. 2000 is a leap year, 1900 is not a leap year).

How to calculate leap years:

Generally, if the number of Gregorian years is a multiple of 4, it is a leap year, otherwise it is a common year;

However, if the Gregorian calendar year is a whole number of hundreds of years, it must be a multiple of 400 to be a leap year, and a multiple of 400 is a common year.

365 days in a normal year and 366 days in a leap year.

2016/4=504...0 and 2016 is not a whole hundred, therefore, 2016 is a leap year, 366 days.

1. For non-whole 100 years:

Divide the year by 4, if it is divisible, it is a leap year, if there is a remainder, it is a common year;

2. For a whole hundred years:

Divide the year by 400, which is a leap year if it is divisible, and a common year if there is a remainder.

For example: 2016 4=504, so 2016 is a leap year, 2017 4=504....1, so 2017 is a common year;

2000 400 = 5, so 2000 is a leap year, 1900 400 = 4....300, so 1900 is a common year.
