Introduction to calendar

China began to have a calendar about 4000 years ago. According to a page of Oracle bone calendar in Oracle Bone Inscriptions, it is proved that the calendar of Yin Dynasty has reached a considerable level. This page of Oracle Bone Inscriptions is the oldest almanac in the world, also called the calendar. The real calendar was thus created. About 1 100 years ago, the imperial calendar was already used in Yongzhen Garden and Palace in Tang Shunzong.

The first day is a page, recording the state, court events and the words and deeds of the emperor. The imperial calendar is divided into twelve volumes, each volume has the same number of pages as the number of days per month, and each page indicates the number of days and dates. Nowadays, popular calendars, whether paper publications, mobile phone applications or electronic desk calendars, usually include solar calendars, lunar calendars and dry calendars.
