The first calendar in China was 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 calendar in the world, also called the calendar.

Calendar from ancient times to the present, there are three versions: 1. Calendar or something. This refers to books with years, months, days, weeks, solar terms, anniversaries, etc. One book a year, one page a day, and withdrawal day by day. Some are hung on the wall, others are on the table. 3. Historians' daily records of national events are the basis for historians to compile national history.

Calendars and desk calendars are all developed from calendars, but this is only a history of nearly a hundred years. As for when the calendar appeared, no one can say for sure, but according to historical records, it was already in use in the palace of Yongzhen Garden in Tang Shunzong about 1 100 years ago. At that time, the calendar, also known as the imperial calendar, not only recorded dates, but also was an important material for compiling national history.

At that time, the calendar divided the year into 12 volumes, determined the number of pages of each volume according to the number of days in each month, and wrote the month and date on each page, and then gave it to the eunuch who served the emperor for temporary storage until the eunuch recorded the emperor's words and deeds on the blank page every day and gave it to the emperor at the end of each month. After approval, they were sent to historians for archiving.

Then, historians combined the contents of the calendar with the events in the imperial court and China, refined them, recorded them and became national history. Later, because the calendar brought a lot of convenience to life, it gradually entered the families of many senior officials in North Korea. After some changes, it was compiled into its own calendar. Later, with the development of popular calendars and family calendars, people printed calendars with lunar calendars, solar terms and auspicious days, leaving a large blank for keeping records.
