When does the Year of the Dog begin?

Lunar calendar algorithm: the year of the dog starts from the first day.

Taking New Year's Eve as the dividing point, that is, from the beginning of the Lunar New Year (the first day of the first lunar month), the method of calculating the zodiac appeared late, and the earliest record appeared in the Northern Song Dynasty. Now many people agree with this. Folklore experts believe that the zodiac should not be calculated according to the 24 solar terms. After all, the Spring Festival is the beginning of the Lunar New Year, and it is also the beginning of the Lunar New Year, so the zodiac naturally starts from the first day of the first month.

Wang Sichao, a researcher at Nanjing Purple Mountain Observatory of Chinese Academy of Sciences, agrees with this view.

Chronology of cadres and branches: counting from February 4th in beginning of spring.

Compared with folklore experts and Wang Sichao, CoCo Lee, secretary general of Jiangsu Astronomical Society, thinks that the zodiac should start in beginning of spring. According to reports, the method of taking beginning of spring as the standard of the zodiac began in the Shang and Zhou Dynasties. The current Chinese zodiac calendar, traditional numerology, divination and other folklore all take "beginning of spring" as the basis for calculating the Chinese zodiac.

"People nowadays rarely remember the old zodiac calendar, and naturally they can't remember the old zodiac algorithm." CoCo Lee said that in ancient China, heavenly stems and earthly branches was also used to record years, months and days. The expression of the zodiac is unique to the chronology of heavenly stems and earthly branches. "There are not only twelve zodiac signs, but also twelve o'clock. This system is different from the lunar calendar. " CoCo Lee said that the chronology of trunks and branches is based on the sun, and the alternation of heavenly stems and earthly branches began in beginning of spring every year. For example, the year of the horse is Wu Jianian, and the year of the sheep is B. According to the chronology of trunks and branches, the length of each year is about 365.25 days.

If you want to see a person's birthday, CoCo Lee said, "This is a day that strictly begins in spring."

Most people agree to start on the first day of the new year.

Since what day on earth? Modern Express reporter found that Baidu's calendar started from the Spring Festival. Most young parents don't know that the zodiac is counted from beginning of spring, but they all think that it should be counted from the Spring Festival. Interestingly, if we count from the Spring Festival, there will be some "no spring" years and some "second spring" years.

Different opinions about the zodiac and the beginning of a year

Beginning of spring is one of the 24 solar terms. Beginning of spring is the first of the twenty-four solar terms, and it was included in the first month solar terms in the official yearbook of Ming and Qing Dynasties. The arrival time is on February 3-5 of the Gregorian calendar every year (around the first day of the first lunar month), when the sun reaches 3 15.

Beginning of spring is one of the important traditional festivals of the Han nationality. "Li" means "start". Since the Qin Dynasty, China has always regarded beginning of spring as the beginning of spring. Beginning of spring is divided from astronomy, with spring flowers and flowers; Spring is growth, cultivation and sowing. The period from the beginning of the Spring Festival to the long summer is called spring.

The zodiac is not bounded by the New Year, but by beginning of spring.

Beginning of spring was once called "Spring Festival", but in the early years of the Republic of China, beginning of spring was robbed of the title of "Spring Festival" by the Lunar New Year. This does not mean that the beginning of spring is a new year. Everyone who has read history books knows this common sense, but some people who don't understand it misinterpret it. It turns out that beginning of spring is the new year. The real new year has always been the first day of the New Year. However, the Zodiac does not take the New Year as the boundary, but takes beginning of spring as the boundary, because beginning of spring is the first day of each year in the heavenly stems and earthly branches calendar of the lunar calendar, which is the day when the main branch enters the next year, and the Zodiac is only the agent of the twelve branches.
