Why does the calendar divide into lunar and Gregorian calendars, and what calendars are divided into

October 15, 1997 is Friday, November 14, 1997 in the Gregorian calendar.

It explains the difference between the lunar calendar, the solar calendar, the lunar calendar, and the Gregorian calendar.

The calendar is divided into lunar and gregorian calendars.

The Gregorian calendar is also the Gregorian calendar, and the Gregorian calendar is called the "Gregorian calendar". The Common Era, also known as the Western Calendar or Western Era, is a method of chronology that originated in Western society.

The lunar calendar refers to the lunar calendar, which is the traditional Chinese calendar, and is known as the Chinese calendar, the summer calendar, the Chinese calendar, and so on. The lunar calendar takes the change cycle of the moon phase, that is, the synodic month as the length of the month, adds the "24 solar terms" component of the Ganzhi calendar, refers to the length of the solar return year, and sets the leap month to adapt the average calendar year to the return year.

The difference between the lunar calendar and the solar calendar

1. The time is different: the lunar calendar is 12 months in a normal year, and the annual time is 354 days or 355 days. The Gregorian calendar has 365 days in a normal year and 366 days in a leap year, with a leap year every four years.

2. The number of days is different: the length of the calendar month is determined according to the celestial phenomena to determine the lunar calendar, the big month is 30 days, and the small month is 29 days. The Gregorian calendar has 31 days for the big month and 30 days for the minor month, and the special number of days in February is 28 days in ordinary years and 29 days in leap years.

3. Different names: The lunar calendar is commonly known as the lunar calendar, and the usual name is the beginning of the month for the first day of a certain month, such as: the beginning of September.

Eighth, the beginning. 9. The tenth day of the first month; Mid-month: September.

Ten. V.XVI; The end of the month is September 30, and the word "day" is not added after the salutation. The Gregorian calendar, also known as the Gregorian calendar, is usually called a certain day of a certain month, such as: March 12, April 20, May 31, the time must follow the word "day".

Here's how to distinguish between the Gregorian and lunar calendars:

The Gregorian calendar is the Gregorian calendar: we now mainly use the internationally accepted calendar, the Gregorian calendar. It is based on a solar return year as a year, and then divided into 12 months (the number of months has 31 days, 30 days, and 29 days, all of which are artificially prescribed), and it is called the solar calendar, that is, the solar calendar.

In addition to the Gregorian calendar, China has retained the calendar that has been used since the Xia Dynasty: the summer calendar, which is based on the twelve moons as a year, so that the time of the year is more than ten days less than a solar return year, so it is called the lunar calendar (the moon is called the lunar calendar). It also contains the knowledge of the 24 solar terms and other calendars, which are closely related to agricultural production, so it is also called the lunar calendar.

The way to distinguish is very simple, the calendar is generally written on the solar calendar and the lunar calendar at the same time. The number is written in the solar calendar, such as September 12. The Chinese characters are written on the lunar calendar, such as the third day of the seventh month.

The Gregorian calendar is the internationally accepted calendar, also known as the Gregorian calendar. The lunar calendar is a calendar summarized by the laws of agricultural cultivation in some countries such as China, also called the lunar calendar.

The Chinese lunar calendar is a lunisolar calendar, the lunar calendar (lunar calendar) is about the fifteenth day of the first lunar month, the sexagenary branch is about the relationship between the sun and the earth, it is the solar calendar, and the 24 solar terms and the December are the basic contents.

There is a process in the formation of the Ganzhi calendar, which begins with the era. The Ganzhi era appeared as early as the Shang Dynasty, the Spring and Autumn Period and the Warring States Period had adopted the 12 Chen Ji Yue, and the 12 Chen plus time system had been adopted by the Western Han Dynasty at the latest.

Since the end of the Western Han Dynasty, it has been used to chronicle the year. After the Tang Dynasty, the name of the month of the five old selling dynasties began to be annotated with the dry branch, and the Northern Song Dynasty and the ten dry and twelve Chen were combined with the dust to tease the time, and the year, month and day were all annotated with the dry branch, and the dry branch calendar became more and more complete. Over the past 2000 years, the Chinese Ganzhi Chronicle and the Calendar Chronology have not only cooperated with each other, but also contained their own systems.

In fact, the Chinese calendar system is a unique Gregorian calendar system.

Duan A: The lunar calendar is the lunar calendar in China, which calculates the date based on the cycle of the moon, and the calendar is the solar calendar, which is calculated by the cycle of the sun;

The lunar calendar was invented in our country, and now the traditional festivals in our country are all used in the lunar calendar high burning date, such as the Spring Festival, Dragon Boat Festival, Chongyang, Mid-Autumn Festival, etc., the solar calendar is now the international calendar, and the calendar we now hang in our home generally uses the solar calendar, and the lowercase numbers on the general calendar are written on the date of the solar calendar, and the date of the lunar calendar is written with uppercase numbers.
