What is worth knowing about the calendar?

Nowadays, the calendars and desk calendars necessary for every family are all developed from calendars, but this is only a history of nearly a hundred years. As for when the calendar appeared, no one knows, but according to historical records, it was used 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. The calendar at that time was similar to the present one. The year is divided into 12 volumes, and the number of pages in each volume is determined according to the number of days in each month, with the month and date written on each page, and then handed over to the eunuch who served the emperor for temporary storage. The eunuch wrote down the words and deeds of the emperor on the empty page every day and gave them to the emperor at the end of each month. After the approval, it was sent to him. 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 popularization and family development of calendars, people also printed calendars on the calendars, solar terms and auspicious days of the Chinese zodiac, leaving a large blank for keeping records.
