When does the spring breeze start in 2023?

The spring breeze in 2023 began on March 2 1 day.

The vernal equinox is one of the 24 solar terms. The sun passes through a period of 0 ~ 15 on the ecliptic, about 15 days, from March 2 1 (or 20th) to April 5 (or 6th) every year. In a narrow sense, it refers to the moment when the sun passes through the intersection (ascending intersection) of the equator and longitude 0 on the celestial sphere, that is, March 2 1 (or 20).

On this day, the sun shines directly at the equator, and the world is almost as long as day and night. After that, the position of direct sunlight moved northward, and the days in the northern hemisphere were long and the nights were short. Astronomy stipulates that the northern hemisphere begins in spring, and the wintering crops enter the spring growth stage.
