One of the questions in the Ant Manor small class on March 21, 2023 is: In ancient times, the spring equinox was also called the vernal equinox. What did it mean? You may not know the answer to this question, so what is the answer to this question? Now the answer is provided for everyone, let’s take a look.
Answer: Spring is half over
The vernal equinox was also called the "midday equinox", "day and night equinox" and "mid-spring moon" in ancient times. "History of the Ming Dynasty·Liyi" said: "The equinox is the point where yellow and red intersect. When the sun travels here, day and night equinox." Therefore, the meaning of the vernal equinox, firstly, refers to the equinox of day and night, each of which is 12 hours; secondly, it is the ancient equinox. Spring is from the beginning of spring to the beginning of summer, and the vernal equinox is within the three months of spring, dividing the spring equally.
