What is the name of the lunar calendar? When it comes to a day in life, some people will say the date of the lunar calendar, while others will say the date of the lunar calendar, so that many people can't tell the difference between calendars. In fact, there are many sayings about the lunar calendar. Below I sorted out what the name of the lunar calendar is.

What is the name of the lunar calendar? 1 Lunar calendar, the traditional calendar of China. According to the cycle of the moon phase, each moon phase changes to one month; A tropical year is divided into 24 segments, forming 24 solar terms. By referring to the tropic year of the sun, leap months are set to adapt their average calendar year to the tropic year. The lunar calendar combines the lunar calendar with the solar calendar to form a method of combining yin and yang.

The lunar calendar is also called summer calendar, lunar calendar, old calendar, middle calendar and lunar calendar. Because of the use of Xia Zheng, it was often called Li Xia in the old society. After 1970, Li Xia was renamed as Lunar Calendar. The lunar calendar is a combination of yin and yang, and the years are divided into flat years and leap years. An average year is twelve months; A leap year is thirteen months. A month is divided into a big month and a small month, with 30 days in the big month and 29 days in the small month, and its average calendar month is equal to the full moon.

Basic calendar

Calendar is a rule to measure a long time interval, judge climate change and predict the arrival of seasons according to the natural laws of astronomical changes. According to calendar year, calendar year and calendar month, it is divided into ephemeris, solar calendar, lunar calendar and yin-yang calendar. There are four general calendars: the lunar calendar (monthly calendar), the solar calendar (solar calendar), the ephemeris (Beidou calendar) and the combined calendar of yin and yang. The calendar with the moon as the basic unit is the lunar calendar, the calendar with the solar year as the basic unit is the solar calendar, and the calendar with the rotation of the Big Dipper as the basic unit is the ephemeris. In the lunar calendar, its basic calendar rules have been gradually improved and formed by generations, and its form has continued to this day. Lunar calendar is a kind of calendar formed by integrating solar calendar elements on the basis of summer calendar (lunar calendar). The lunar calendar is usually mistakenly called the lunar calendar among the people, but it actually belongs to the yin-yang calendar. [ 1-2]

The phase of the moon

Summer calendar, also known as lunar calendar, old calendar, lunar calendar, etc. , is a kind of lunar calendar, which is based on the law that the moon revolves around the earth. Take the moon's orbit around the earth as a month, that is, take the new moon as the basis for determining the calendar month. A month in the summer calendar is called "Shuowangyue". The first day of each month is a new moon, and the fifteenth day is a new moon. The "new moon" is the average period of the moon's profit and loss. The summer calendar only looks at the moon, regardless of the tropical year, so it has nothing to do with the four seasons. Because the lunar calendar (China calendar) is based on the change of the moon phase, it does not consider the movement of the earth around the sun, so it cannot reflect the seasonal changes to accurately guide farming. Although the summer calendar can't accurately reflect the seasons and guide farming, it can reflect the tides, which are dominated by the moon. The lunar calendar based on the change of moon phases is a guide to ancient navigation activities. Ocean navigation, offshore fishing, mariculture, ocean engineering and various coastal production activities are all affected by tides. Tide refers to the periodic movement of seawater under the tidal force of celestial bodies (mainly the moon and the sun), which is a natural phenomenon in coastal areas. In ancient China, the tides during the day were called "tides" and those at night were called "solar tides", which were collectively called "tides". Its occurrence is related to the gravity of the sun and the moon, and also corresponds to the lunar calendar. On the first day of each month in the summer calendar, the sun and the moon are on one side of the earth, so there is the largest tidal force, which will cause a "spring tide". Near the 15th or 16th day of each month in the summer calendar, the sun and the moon are on both sides of the earth, and the tidal force of the sun and the moon will also cause a "spring tide". The first quarter and the last quarter of the month, that is, on the eighth and twenty-third days of the summer calendar, the tidal force of the sun and the tidal force of the moon cancel each other out, so a "small tide" occurred.

Elephant trunk calendar, also known as ephemeris, Jiazi calendar, solar calendar or China Gregorian calendar, is an abstruse calendar, and the establishment of 24 solar terms and December is the basic content of elephant trunk calendar. The ancients took heavenly stems and earthly branches as the carrier, and the heavenly stem carried the way of heaven, and the earth supported the way of the earth; In nature, it takes shape underground, in human luck; Dry as the sky and supported as the earth. Although everything grows on the ground, the rise and fall of Rong Sheng is inseparable from the sky. Heavenly stems and earthly branches contains profound cosmic astrological codes. The ancients thought that the evolution of everything in the world could be calculated by it. Ten stems and twelve branches combine to form sixty jiazi. The trunk and branch calendars are 60 groups of heavenly stems and earthly branches combinations consisting of 10 heavenly stems and 12 earthly branches, which are used to mark calendars of years, months and days. The calendar divides a year into December construction, and "construction" represents the direction of the top of the bucket handle of the Big Dipper; In ancient astronomy, bucket handle, the Big Dipper, or Sword for short, in the middle of a year, bucket handle refers to the twelve days in turn, which is called "December Sword". December architecture: Yin in the first month, Mao in February, Chen in March, Si in April, Wu in May, Wei in June, Shen in July, You in August, Xu in September, Hai in October, Zi in November and Ugly in December. A year from beginning of spring to the next beginning of spring is one year old, twelve months divided by twenty-four solar terms, each month contains two solar terms, and there is no leap month. It takes beginning of spring as the beginning of the year and festivals as the beginning of the month. Also different from the usual solar calendar (such as the Gregorian calendar), the length of the Gregorian calendar is artificially specified and has nothing to do with the astronomical phenomena; The year, month and day of the elephant trunk calendar are determined by the astronomical phenomena and do not need to be adjusted artificially. It is a calendar that completely conforms to the laws of the astronomical phenomena. At present, dry calendars are still popular in books such as perpetual calendars, which are used for astrology, geomantic omen and numerology.

What is the name of the lunar calendar? Lunar calendar is a calendar used in parallel with solar calendar in China at present, and the commonly referred lunar calendar is also called lunar calendar and summer calendar. It is a kind of calendar in China, and it is also a kind of lunar calendar, commonly called lunar calendar. Normal year 12 months, 30 days in the big month, 29 days in the small month, and 354 or 355 days in the whole year (which month is big and which month is small in a year, which varies from year to year). Because the number of days in each year is about eleven days worse than that in the solar year, there are seven leap months in nineteen years, and there are 383 or 384 days in a year with leap months. According to the position of the sun, a solar year is divided into 24 solar terms to facilitate agricultural planting and other activities. The chronology is matched with heavenly stems and earthly branches, with a period of 60 years. According to legend, this calendar originated in the Xia Dynasty, so it is also called the Xia calendar. Also known as the old calendar.

The solar calendar takes one year as the time for the earth to go around the sun. Its length is 365 days, 5 hours, 48 minutes and 46 seconds. Because it is not an integer, in order to balance the length, some years are 366 days, called "leap year"; Some years are 365 days and are called "average years".

The lunar calendar is based on the cycle of the moon, which is the new moon. The main feature of the lunar calendar is that the length of the calendar month is determined according to the astronomical phenomena, that is, the phase of the moon, with the big moon on the 30th and the small moon on the 29th.

Gregorian calendar = Gregorian calendar 02 is a universal date, which is our usual date.

Lunar calendar = lunar calendar 02 is the date used for farming in ancient China, that is, the date indicated by the small print below the calendar.

The difference between lunar calendar and lunar calendar

1, the lunar calendar is a lunar calendar, but the lunar calendar is not just a lunar calendar. The lunar calendar handed down in ancient China is a combination of yin and yang, including the lunar calendar recorded by the moon cycle, represented by the "full moon on August 15th". It also includes "Tomb-Sweeping Day", which is represented by "solar terms" and always falls on April 5th every year.

So we often see the saying "the seventh day of the seventh lunar month, the ninth day of the summer" on the calendar. The seventh day of the seventh month of the lunar calendar is the lunar calendar representation in the lunar calendar, while the ninth day of the summer is the solar calendar representation in the lunar calendar.

Literally, the solar calendar is the abbreviation of "solar calendar". The lunar calendar is divided into lunar calendar and solar calendar, which is such a representation. However, since the adoption of the western "AD calendar", the current solar calendar is basically dedicated to the "AD calendar", that is, the "solar calendar". This is mainly related to our habits. Because most date records and festivals in China are defined according to the lunar calendar in the lunar calendar. For example, "New Year's Eve" is the thirtieth day of the twelfth lunar month, and 2008 is the first day of the first month. Dragon Boat Festival and so on. It seems that there is only one "Tomb-Sweeping Day" that is not a festival. The solar calendar of the lunar calendar is 24 solar terms, mainly serving agricultural production. Speaking of it, the solar calendar in the lunar calendar can better represent the title of "lunar calendar"

What is the name of the lunar calendar? The lunar calendar is one of the traditional calendars in China, also known as the old calendar, the Han calendar and the ancient calendar. After the revolution of 1911, it was changed to the western solar calendar (Gregorian calendar), while the modern lunar calendar belongs to the yin-yang calendar.

In China's traditional calendar, the lunar calendar mainly refers to the calendar arranged according to the periodic changes of the moon phases, that is, the calendar with the first month of the lunar calendar as the basis for determining the calendar months and twelve calendar months in a year. In the process of the development and evolution of the calendar, it combined with the 24 solar terms in the trunk calendar to form the lunar calendar (Han calendar), which was used to guide agricultural production scientifically. Although the lunar calendar and lunar calendar are commonly known as ancient calendar, Han calendar and old calendar, there are differences between lunar calendar and lunar calendar (Han calendar). The traditional lunar calendar (Han calendar) is actually a combination of yin and yang, not a traditional lunar calendar.

The lunar calendar determines the moon on the basis of its motion law: the orbit of the moon is called the white road, and both the white road and the ecliptic road are two great circles on the celestial body, which intersect at five degrees and nine minutes. The moon goes around the earth once and appears on the ecliptic twice, lasting 7 hours and 43 minutes 1 1.5 seconds (27.32 days), which is called the "sidereal moon". Only when the moon revolves around the earth, the position of the earth changes because of its revolution around the sun. The forward number exceeds 27 degrees, and the moon runs 13 degrees 15 minutes every day, so it takes 29 days 12: 44: 2.8 (29.53 days) for the moon to return to the moon, which is called "the first month" and is called the month by custom.
