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 year of the lunar calendar. 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 time beginning of spring will be in the first month of 2020 1 1 day, so there will be no beginning of spring on 20 19.

"No spring year" refers to a year in which there is no beginning of spring in the whole year of 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 popular folk saying that "I am not suitable for marriage without spring", but there is no scientific basis.

The dates of solar terms in the summer and lunar calendars are not fixed. China's traditional calendar summer calendar is a combination of yin and yang: "Yin" means that the average length of its calendar month is 29.5306 days, and the first day of each month is the first day; "Yang" refers to the Spring Festival, which is based on the tropical year and takes the first day of the first month around beginning of spring every year as the first day of the first month of the year.

/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 (New Year's Eve can be divided into 26 solar terms when the solar terms coincide with those of rain), so there is a "beginning of spring" at the end of the first year, which becomes a "double spring year", while the second year has only 23 solar terms, so there is 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.
