What is a leap month?
Leap, the original meaning is remainder. Refers to the difference between the Gregorian calendar year and the execution time of the earth's orbit around the sun.
The extra one is called leap. Leap month means every leap year plus one month. Leap moon refers to a phenomenon in the lunar calendar. What is leap April?
In the lunar calendar, the reference to the month comes from the movement of the moon. It is stipulated that the beginning of a month is when the moon is in the position of the new moon (the moment when the moon is between the sun and the earth), and the time from the new moon to the next new moon is called "full moon".
The average is 29.530589 days. There are usually 12 moons in a year, but the 12 moons are only 29.530589 * 12 = 354.367068 days, which is less than 365.2422 days in tropical years. So every few years, there will be a bright thirteenth month-the so-called "leap month", and it will be corrected. Regarding the arrangement of leap month, the ancients subdivided the 24 solar terms of the lunar calendar into solar terms and neutral terms, with the beginning of a single spring day such as beginning of spring and Jing Zhe as solar terms, and every two days such as rain and vernal equinox as neutral terms. According to the calendar, every month must contain a corresponding "mild" atmosphere, such as rain in the first month and vernal equinox in February, so that months can adapt to the season. If there is only a "mild" atmosphere in a month, then this month is designated as a leap month in the previous month. Leap months are arranged according to the rules of the calendar itself. For example, 200 1 (Xinsi year of the snake), Xiaoman is May 2 1 (April 29th of the lunar calendar), and the first day of the next lunar month is May 23rd. However, this lunar month ends on June 20, and the summer solstice falls on June 2 1 day, so this lunar month is not "neutral", but in.
