Is next year a double spring year?

Next year, 2023 is the year of double spring.

The so-called "Double Spring Year" means that a lunar year has two "beginning of spring" solar terms. As next year is a leap month, the Lunar New Year will have 13 months and 384 days. Due to the extension of the lunar calendar and the fixed time of the 24 solar terms, there may be 25 solar terms in a lunar year, that is, there is a beginning of spring solar term at the beginning and end of the year, which is called "Double Spring Year".

2023 is the year of Guimao (Rabbit). When we open the calendar, we will find that there is a leap February in the lunar calendar in 2023, that is, there are two lunar February, and the lunar calendar has 384 days in a year.

The existing calendars are lunar calendar, solar calendar and lunar calendar. Among them, the lunar calendar is a calendar based on the changes of the moon's profit and loss; The solar calendar is a calendar based on the earth's revolution around the sun; The lunar calendar is based on the phase change of the moon and the length of the solar year. So the solar calendar is a combination of the lunar calendar and the solar calendar. Compared with the lunar calendar, the solar calendar has 24 solar terms and leap months. It can be said that the lunar calendar is a part of the lunar calendar.

Reasons for adding "leap month":

This is because the average lunar month is 29.5 days,1February is 354 days, and the tropical year of a solar calendar is about 362.25 days. The difference between them is 1 1 day, and it will exceed 1 month after three years. In order to coordinate the contradiction between the lunar year and the tropic year and prevent the disconnection between them, a leap year is set every 2-3 years on the lunar calendar.

For example, 2020 is leap April, 2023 is leap February, and 2025 is leap June. At present, the method of "seventeen leap years in nineteen years" is adopted, and there will be seven leap years every 19, and each leap year has thirteen months.

2023 is leap February, and the year after leap February is 2042, with a difference of 19 years.
