20 13 why is there no spring year?

"A year without spring" means that a year in the lunar calendar does not conform to the "beginning of spring" solar terms.

20/0/3 of beginning of spring is on February 4th, and the Spring Festival is on February 10. The next Spring Festival is 20 14 65438+ 10 3 1, before beginning of spring on February 4th. In other words, there is no "beginning of spring" solar term in the whole year of the lunar calendar, which is called "no spring year".

A normal Gregorian calendar year is 365 days, while the last year of the lunar calendar has only 355 days, which happens to be "in the middle of nowhere, in the middle of nowhere" and there is no beginning of spring.

All the years without spring occur in the "normal years" of the lunar calendar.

The next year without spring is 20 16.
