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 electronic calendars.

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. Calendars are often decorated with images, and monthly cards are one of the decorative paintings 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 calendar year is the tropic of Capricorn.

The lunar calendar is also called the lunar calendar, or lunar calendar. Its calendar month is a new moon, the Gregorian 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 a flat year and a leap year in the lunar calendar. The number of days in a year is quite different, and the calendar month is a new moon.

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

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