What does it mean to hit six or nine heads in spring?

This means that spring begins on the first day of June 9.

The original sentence is "spring knocks five or nine times, and spring knocks six or nine times." This folk proverb means that the beginning of spring is either the last day of May 9th or the first day of June 9th.

In ancient times, the period from winter solstice to winter solstice (about 365.25 days), that is, the tropical year, was usually divided into 24 segments (each segment was about 15: 05), that is, 24 solar terms. Because the interval between every two solar terms in the 24 solar terms is about 15.2 days, and the three solar terms are 45.6 days (45th day 14 hours), the time of winter solstice determines the time in beginning of spring.

If the winter solstice time is before 10 that morning, it will be beginning of spring after 45 days; If the winter solstice is after 10 am, there are still 46 days from beginning of spring. There is also a saying that beginning of spring's time is not dead, but will change, so there is a phenomenon of "spring beating five Kyubi no Youko".

How to calculate

The so-called "number nine" means that "winter solstice" is 1 day of "September 19", and the first day of "June 9" is the 46th day from winter to the future (including the day of winter solstice); Beginning of spring is the third solar term after the winter solstice (winter solstice, slight cold and severe cold), which is generally a solar term of 15 days, so "beginning of spring" is the 46th day after the winter solstice (including the day after the winter solstice), so beginning of spring is generally on the first day of June 9th, that is, "beginning of spring hits six or nine heads". But there are exceptions

For example, 20 1 1 and 20 12, beginning of spring hit five Kyubi no Youko on the last day of May 9, instead of hitting six or nine heads. This may be because the "Ninth Five-Year Plan" also takes the lunar calendar as the calculation point. The winter solstice of 20 1 1 is 65438+February 22nd. If it is 2 1, then beginning of spring on 20 12 will be the first day of June 9.
