What does the double spring year in 2024 mean?

The double spring year means that there are two solar terms in beginning of spring in a year.

The double spring year means that there are two solar terms in a year, beginning of spring, which is caused by the "strange spirit" between the solar calendar and the lunar calendar. The solar calendar is made according to the law of the earth's revolution around the sun, and the revolution of the earth 1 is 1 year, which is divided into 12 months, which is 365 days.

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 a combination of the cycles of the sun and the moon.

In this way, there is a deviation of 1 1 day between the lunar calendar and the solar calendar, so the lunar calendar has a "leap month" to solve the time difference problem of the lunar calendar.

Double Spring means that there will be two beginning of spring in the lunar calendar year, while the traditional lunar calendar in China is a combination of yin and yang: "Yin" means that its calendar month is based on the month, with Shuotian as the first day of each month, and "Yang" means that its calendar year is basically based on the Tropic of Capricorn, and the first day of the first month of each year is Shuotian around beginning of spring.

The average year of the Gregorian calendar 12 is only 354 days or 355 days, while that of individual years is only 353 days, that of 13 years with leap months is 383 days or 384 days, and that of individual years is 385 days, which can include 25 solar terms. In this way, there is a "beginning of spring" at the beginning and the end of each year, which becomes a double spring year.
