After the Revolution of 1911, China began to introduce the western Gregorian calendar, commonly known as "solar calendar" and "new calendar", with names corresponding to the original calendar of China. After the founding of New China, the Gregorian calendar was officially adopted. The lunar calendar, also called the lunar calendar, is mainly based on the law that the moon revolves around the earth.

A month in the lunar calendar is called a "new moon". The first day of each month is a new moon, and the fifteenth day is a new moon. The "new moon" is the average period of the moon's profit and loss. The so-called "full moon and sunny" means this.

The lunar calendar is based on the laws of the moon and the solar calendar is based on the laws of the sun. Because the cycles of the sun and the moon can't match, this leads to a difference of about eleven days between the lunar calendar and the solar calendar every year.
