When the leap month meets the Spring Festival, it can only celebrate the first day of the first lunar month, and the first day of the leap month is not counted as any festival. Of course, after the Spring Festival and the Lantern Festival of the first first month in a few regions, the Spring Festival and the Lantern Festival of the leap first month also occur in the leap first month. Because the leap first month is also called the first month, the first day and the fifteenth day of the leap first month are also regarded as the Spring Festival and the Lantern Festival.
Introduction to leap month: leap month is a way to place a leap in the calendar. In Asia, especially in China, the leap month refers to one month added every leap year in the Han calendar. In order to coordinate the contradiction between the year of regression and the Han calendar year, and prevent the year of regression and the four seasons of the Han calendar from being disconnected, a leap was placed every two to three years. In ancient times, seven leap weeks were used in 19 years. By the time of the "Linde Calendar" in the Tang Dynasty, the fixed leap weeks were abolished and the non seasonal months were used, Therefore, the leap is placed when the leap occurs. Sometimes, leap month also refers to the month containing leap day in the leap year of the Gregorian calendar.
