The vernal equinox is when the sun shines directly on the equator. Day and night are equal in the northern and southern hemispheres, which means that day and night are divided into twelve hours. The proverb says, "Eating the vernal equinox makes the day longer."

The vernal equinox is of great significance in astronomy. On the day of the vernal equinox, the sun shines directly on the equator, and the northern and southern hemispheres are divided equally day and night. Since then, the direct position of the sun has continued to move from the equator to the northern hemisphere. In the northern hemisphere, the day begins to be longer than the night, while in the southern hemisphere, it is the opposite.
