Is there no beginning of spring on 20 19?

Yes, 20 19 is a year without spring, which means that there is no year of beginning of spring in the whole lunar year. The Spring Festival in 20 19 is on February 5th, and beginning of spring is just the day before it, that is, New Year's Eve, so it still belongs to 20 18 on the lunar calendar. The next beginning of spring will be on January 1 1 day in 2020, so there will be no beginning of spring in 20 19.

"Spring-free year" refers to the year when there is no beginning of spring in the lunar calendar. In order to adapt to the changes of cold and summer, the ancients added seven leap months every 19 years in the lunar calendar, resulting in no beginning of spring for seven years in 19 years. There is a saying among the people that "I am not suitable for marriage if I have no spring", but there is no scientific basis.

The solar terms in the summer calendar and the lunar calendar are not fixed. China's traditional calendar summer calendar is a combination of yin and yang: "Yin" means that its calendar month is 29.5306 days based on the average length of Shuoyue, and Shuori is the first day of each month; "Yang" refers to the Spring Festival, that is, the first day of the first month in a year based on the tropic year, and the first day of the first month of each year is before or after beginning of spring.

/kloc-the average lunar year of 0/2 months is only 354 or 355 days, and some years are only 353 days. A leap month 13 has 383 or 384 days in a year, and some years have 385 days, which can contain 25 solar terms (when New Year's Eve coincides with rain solar terms, it can be divided into 26 solar terms), so that at the end of the first year, there will be a "beginning of spring" and it will become a "double spring year", while the next year will have only 23 solar terms, so there will be no "beginning of spring" and no spring.

It can be seen that "no spring" after "double spring" is completely the result of calendar arrangement according to certain rules, and it often appears.
