What are the years in a normal year? What are the years of a common year

The year divided by 4 is a common year (February has only 28 days), and the leap year (February has 29 days), such as 2001, 2002, 2003, 2005, and 2006 are all common years. A leap year is divisible by 400 in a full hundred years.

Calculation method: Follow these steps to do it:

1: Divide the year by 4, the remainder is the common year, and the one that does not do the next step;

2: Divide the year by 100, the remainder is the leap year, and the one that does not have it will do the next step;

3: Divide the year by 400, the remainder is a common year, and the none, a leap year.

Leap year condition (1) A year that is divisible by 4 but not divisible by 100 is a leap year.

2) The ones that are divisible by 400 are also leap years, and all other than these are common years.

For example, 1000 years can be divisible by 4 and also divisible by 100.

If it doesn't meet any of the above conditions, it's a normal year.

In 2000, it did not meet (1) but met (2).

So it's a leap year, and 2004 qualifies as a (1), which is also a leap year.

There is a leap in four years, no leap in a hundred years, and another leap in four hundred years.

2017, 2018, 2019, 2021, 2022 and many more.

1. To judge whether the year is a leap year, you only need to look at the last two digits of the year, if the last two digits are divisible by 4, then it is a leap year, otherwise, it is not.

2. When we encounter a year where the last two digits are 0, we look at the first two digits of the year; If the first two digits are divisible by 4, then it is a leap year, and vice versa, it is not.

3. If you encounter that the two digits at the end of 2004 are 04, you can directly regard it as a 1-digit number, if this number can be divided by 4, then it is a leap year, otherwise, it is not.

A year in which there is no leap day in the solar calendar, or when there is no leap month in the lunar calendar, is called a common year. Divide the non-whole hundred years by 4, or the whole hundred years by 400, if not divisible, it is a common year. In a normal year, February has only 28 days.

The ordinary year of the solar calendar is 365 days, the ordinary year of the lunar calendar is generally 354 days or 355 days, and very rarely 353 days. Between the first year of the lunar calendar and the year 5000 AD, the lunar year had a year of 353 days.

How to judge the common year

1) To judge whether the year is a normal year, you only need to look at the last two digits of the year, if the last two digits are not divisible by 4, then it is a common year; Not the other way around.

2) In a year where the last two digits are 0, we look at the first two digits of the year, if the first two digits are not divisible by 4, then it is a common year; Not the other way around.

3) If you encounter the year 2004 (the last two digits are 01 09), you can directly regard it as a single digit, if this number is not divisible by 4, then it is a common year; Not the other way around.

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

The rest are ordinary years.

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

What is a common year and what is a leap year.

In general, a year divisible by 4 is a leap year, and a year not divisible by 4 is a common year. For example, 1988 and 2008 are leap years; 2005, 2006 and 2007 were normal years.

But if it is a century year (that is, a whole hundred years), only divisible by 400 is a leap year, otherwise it is a common year. For example, 2000 is a leap year, 1900 is a common year, February has 29 days, and February of a normal year has only 28 days.

The difference between a common year and a leap year.

The time it takes to revolve around the sun is called a year. Because the time it takes for the Earth to revolve around the Sun is about 365 days, 5 hours, 48 minutes and 46 seconds. Therefore, the Gregorian calendar stipulates that there are common years and leap years.

A year with 365 days as a year is called a common year. A year with 366 days as a year is called a leap year. The calculation method for ordinary years and leap years is "one leap in four years, no leap in one hundred years, and another leap in four hundred years".

According to this calculation, the year of the Common Era that is not divisible by 4 is a common year, the "year of a hundred" that is divisible by 4 is a leap year, the "year of a hundred" that is not divisible by 400 is a common year, and the number of years of the Common Era that is divisible by 400 is a leap year. For example, 1992 is a leap year, 2000 is a leap year, and 2100 is a common year.

Common year. Ordinary years and leap years are an indispensable unit of year calculation in our national Gregorian calendar, the year is very important to us, is used to calculate time, preserve historical stories and other major events, having a stable calendar is a blessing for mankind!

Question 1: What are the years of a normal year? The number of years in Common Era is divisible by 4 as leap years, but the number of years with a hundred must be divisible by 400 to be leap years.

Everything else is an ordinary year. February in leap years has 29 days. For example:

1996 is a leap year, 2000 is a leap year, and a common year has 28 days in February, 1900 is a leap year, and 1997 is a common year. The year in which there is a leap month in the lunar calendar is called a leap year, and the leap year that can be divisible by 4 is the open code brigade.

Question 2: What are the leap years from 1696 to 2032? Those are the ordinary years?

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

The rest are ordinary years.

Question 3: Excuse me: What are the years in a common year Except for the years that are divisible by 4, they are all common years Question 4:

What is a common year and what is a leap year 365 days is a common year and 366 days is a leap year Question 5: What are the years in a common year The number of years in Common Era can be divisible by 4 as leap years, but the number of years with a hundred must be divisible by 400 to be a leap year. Everything else is an ordinary year.

February in leap years has 29 days. For example, 1996 is a leap year, 2000 is a leap year, and a normal year has 28 days in February, 1900 is a leap year, and 1997 is a common year.

The year in which there is a leap month in the lunar calendar is called a leap year, and a leap year is divisible by 4.

Question 6: How many days are there in a normal year and how many days are there in a leap year? Ordinary year 365 leap year 366

The law of leap years in the Gregorian calendar is: one leap in four years, no leap in one hundred years, and then leap in four hundred years.

The rules for leap years are as follows:

An ordinary year is a leap year that is divisible by 4 but not by 100. (For example, 2004 is a leap year, and 1900 is not a leap year).

A leap year is a leap year that is divisible by 400 but not by 3200. (e.g. 2000 is a leap year, 3200 is not a leap year).

A year with a large value is divisible by 3200, but at the same time divisible by 86400 is a leap year. (e.g. 86400 is a leap year).

The year divided by 4 is divisible as a leap year.

If not, it will be a normal year.

For example, the year 2000 divided by 4 is divisible and is a leap year.

2001 is not a red celery.

This year, 2016, is a leap year.

Leap years are: 2000, 2004, 2008, 2012, 2016 ......

Ordinary years are: 2001, 2003, 2005 ......

The method of judging flat and leap years: generally the number of years is a leap year as long as it is a multiple of 4, and a multiple of 4 is a common year; The number of copies of the whole hundred years must be a multiple of 400 to be a leap year, and a multiple of 400 is a common year. Classification is carried out after this analysis.

Example: 1840 4=460

There is no remainder, and 1840 is a leap year.

There is a remainder, 1949 is a normal year.

There are leap years for 4 years. Weekdays are almost every year.

Pingnian is a Chinese word, pronounced píng nián, which refers to a year in which the solar calendar does not know that there is a leap day or a leap month in the lunar calendar; The second refers to the average year of crop harvest. A common year and a leap year are called common years when there are no leap days in the Gregorian calendar or when there are no leap months in the lunar calendar. The non-whole 100-year part divided by 4, and the whole 100-year part divided by 400 is the undivisible spring year.

The 365 days of a year are called common years, and the 366 days are called leap years.
