Is the vernal equinox long in the day or short in the night?

During the vernal equinox, whether in the southern hemisphere or the northern hemisphere, the length of day and night is equally divided, which is one of the origins of the vernal equinox name.

On the day of the vernal equinox, the sun shines almost directly on the equator of the earth, and the whole world is almost as long as day and night (regardless of the refraction of the sun's light by the atmosphere and the shadow in the morning). The seasons in the northern and southern hemispheres are opposite. In the northern hemisphere, it is the vernal equinox, and in the southern hemisphere, it is the autumnal equinox.

At the vernal equinox, the direct point of the sun is on the equator. Theoretically, the length of day and night in the whole world is equal (see twilight). After the vernal equinox, the direct point of the sun continued to move northward, and the days in the northern hemisphere became longer and shorter, and the nights in the southern hemisphere became shorter and shorter.
