Who wrote the yearbook?

According to legend, it was created by the Yellow Emperor, so it was called the Yellow Calendar.

Avoid, zodiac luck, etc. In ancient times, the almanac issued by the government announced the year number, festivals and solar terms of the coming year, reflecting the objective laws of natural time changes and meteorological changes, guiding the agricultural production of working people, and also serving as the basis for the signing date of government documents.

The almanac from the Warring States to the Qin and Han Dynasties is called the Japanese almanac. In ancient times, the official position in charge of astronomical calendar was calculated and published in the name of the emperor, so it was also called imperial calendar, and its content guided farmers' farming opportunities.

Since the reign of Qianlong in Qing Dynasty, it was renamed Shi to avoid its name (Li Hong). Until the late Qing Dynasty, the almanac refers to a reference book that arranges the years, months, days and hours according to a certain calendar and indicates the solar terms. Because the word "Shu" in general books is homophonic with the word "lose", it is often called "Tong Sheng" or "Ji Shu" in Cantonese because of taboo.

Almanac existed in China at the latest during the Warring States Period as a guide book for people's lives. Taiding has a five-year period (1328), and there are more than three million official almanac books.

The ancient almanac was promulgated by the imperial court, such as Taishi Order in Qin and Han Dynasties, Taishi Bureau in Tang Dynasty, Si in Song and Yuan Dynasties, Qin in Ming and Qing Dynasties, etc. From the second year of Chongzhen in Ming Dynasty to the seventh year of Chongzhen (A.D. 1629 to 1634), the Calendar Bureau under the leadership of Xu Guangqi hired experts to compile the Calendar of Chongzhen.

When the Qing Dynasty was founded, missionaries sorted out the calendar of Chongzhen and presented it to the Qing emperor as a new book of western calendars. For a long time, studying and studying western astronomy at that time was an important task for astronomers.

In the Qing dynasty, Qin promulgated the next year's yellow calendar on the first day of October every year. Previously, the Qin Committee decided on the new calendar according to whether it was changed to yuan, and submitted it to the emperor, who sealed it by decree. Japanese teachers refer to the imperial imperial prescription book, hang up the hall number and publish the "general book" separately.

Around the ninth year of the Tang Dynasty (AD 835), with the development of printing, almanac carved with wooden boards appeared.
