What does the Spring Equinox mean?

1. The Spring Equinox is one of the 24 solar terms in China. "The Spring Equinox" in "The Spring and Autumn Annals: Yin and Yang, Parts 1 and 2" says: "The Spring Equinox is when Yin and Yang are equal, so the day and night are equal and the cold and heat are balanced." That is to say, on the Spring Equinox, the sunlight is directly on the equator, and the day and night are almost equal. Afterwards, the position of the sunlight gradually moves northward, and the days begin to grow longer and the nights shorter.
2. The Spring Equinox starts on March 20 (or 21) and ends on April 4 (or 5) every year. The vernal equinox begins when the sun reaches 0 degrees of ecliptic longitude (the vernal equinox). The time of the Spring Equinox in 2017 is March 20, 18:28:35, the 23rd day of the second month (big month) in the lunar calendar of 2017, Sunday.

The significance of the Spring Equinox

1. The arrival of the Spring Equinox marks the day when day and night are equally divided, each lasting 12 hours. In ancient times, the spring season lasted from the Beginning of Spring to the Beginning of Summer, and the Vernal Equinox was right in the middle of the three months of spring, dividing the spring season equally.

2. After the Spring Equinox, the climate in most areas also undergoes obvious changes. Most of Northwest China, northern North China and Northeast China are still in the transition stage from winter to spring, but most other areas have entered the bright spring. On the vast land, willows are green, warblers are flying, grass is growing, wheat is growing, and rape flowers are fragrant.
