A calendar is a daily publication that records dates and other related information. Each page displays one day's information as a calendar, one month's information as a monthly calendar, and one year's information as an annual calendar. There are many forms, such as calendars, desk calendars, calendar cards, and now there are electronic calendars.

The first calendar in China was about 4000 years ago. According to a page of Oracle Bone Inscriptions 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. It is also called the calendar. Calendars are often decorated with images, and the month plate is one of the decorative pictures of calendars.

The calendar will display the date of the day in big letters and predict solar terms, luck and other conditions of the day. Calendars in the calendar are divided into lunar calendar, solar calendar and yin-yang calendar. The solar calendar is also called the solar calendar, and its Gregorian calendar year is the tropic of cancer.

The lunar calendar is also called the lunar calendar, or lunar calendar. Its calendar month is a new moon, the calendar year is 12 new moons, the big moon is 30 days, and the small moon is 29 days. The Islamic calendar is one of the lunar calendars. There are obvious differences between the normal year and leap year in the lunar calendar, and there are also great differences in the number of days in a year, and the calendar month is the new moon.

Because there are some differences between 12 lunar month and tropic year, a leap month is set in the lunar calendar to coordinate the relationship between tropic year and lunar month. A year with a leap month is thirteen months, and the lunar month is a leap year.

Generally, there are seven leap years every 19. It is different from the normal year with twelve moons in a year. Therefore, this calendar is consistent with the periodic movements of the moon and the earth around the sun.
