What does it mean that there is no spring for 24 years?

There is no solar term of beginning of spring in the lunar calendar in 2024. A year without beginning of spring solar terms in the whole lunar calendar is called a year without spring. According to the arrangement of traditional lunar solar terms in China, the annual solar terms in beginning of spring are usually between February 3rd and February 5th. However, beginning of spring in 2024 has already appeared before the Spring Festival, resulting in the absence of beginning of spring solar terms in the lunar calendar that year. There is no spring in 24 years, that is to say, in 2024 of the lunar calendar, there is no solar term in beginning of spring, that is, there is no formal spring in the lunar year.

There is a proverb in spring-free years: "I was not cold in spring and December, but it will be busy in June next year." This proverb means that if there is no spring, that is, there is no solar term in beginning of spring in the first month, then the twelfth month will be relatively cold.
