Is the leap month in 2023 correct?

The leap February in 2023 is as follows:

Leaping moon is a traditional way of calendar leap. After leap April in 2020, leap month will come in 2023. According to the calculation method of leap month, 2023 is leap February.

At present, the method of putting leap in the lunar calendar is adopted, one leap in three years, two leap in five years and seven leap in nineteen years. It is generally called "seven leap years in nineteen years", that is, according to the lunar calendar, there are seven leap years in nineteen years

As for the leap month? Need to combine the 24 solar terms in the solar calendar. According to the previous statement, odd-numbered solar terms belong to "solar terms" and even-numbered solar terms belong to "neutral gas". Under normal circumstances, a month includes a solar term and a neutral atmosphere. But under special circumstances, a month only contains solar terms, not gas. According to the traditional calendar, this month will be regarded as a leap month of last month.

For example:

1. For example, in March 2023, there was only Tomb-Sweeping Day gas and no neutral gas (there was only one solar term in the whole month). So according to the above statement, March will be regarded as the leap month of last month, that is, leap February. So, this is the calculation method of leap February in 2023.

2. For example, the expression "Double Spring Year". According to the lunar calendar, beginning of spring in 2023 is the 14th day of the first month, beginning of spring time in 2024 is the 25th day of the twelfth lunar month, solar calendar time is 2023, and lunar calendar time is 2023, so it is called "Double Spring Year".

2023 is not only a leap February, but also a "double spring year". "Double Spring Year" doesn't mean that there are two springs, because spring is a season and there are four seasons in a year, so there can't be two springs. According to the folk lunar calendar, "Double Spring Year" means that there are two solar terms in a year in beginning of spring.
