When are the two beginnings of spring?

The two beginnings of spring are the first year of the lunar calendar.

Say goodbye to the tiger and welcome the rabbit. The Lunar New Year of the Rabbit is coming. Because of the leap month, 2023 is a leap year, and there will be two beginning of spring solar terms in a year, that is, two beginning of spring days in a year. In 2023, 65438+1October 22nd entered the year of Guimao, and in February 2024 10 will usher in the next Lunar New Year-Chen Jianian.

The lunar year of Guimao includes two solar terms in beginning of spring, namely, the first month of Guimao 14 in beginning of spring (February 4, 2023) and December 25, 2024 in beginning of spring. This phenomenon is called spring at both ends of the year, also called double spring year. Compared with the spring at both ends of a year, there are no spring years and no spring years, that is, there is no solar term in beginning of spring or only one solar term in beginning of spring in the Lunar New Year.

Introduction of double spring year

The double spring year means that there are two solar terms in beginning of spring in a year. The double spring year is a unique phenomenon in Chinese calendar, which is actually caused by the "wrong balance" between the solar calendar and the lunar calendar.

The solar calendar is based on the law that the earth revolves around the sun. The revolution of the earth 1 is 1 year, divided into 12 months, and counted as 365 days (366 days in leap years). The lunar calendar is based on the law of the moon's profit and loss. The orbit of the moon around the earth is 1 month, and a year is 12 months. The actual number of days is 354 days.

China's calendar is based on the periods of the sun and the moon, so there is a deviation of 1 1 day between the lunar calendar and the solar calendar, so there is a "leap month" in the lunar calendar to solve the time difference problem in the lunar calendar.
