Autumn Equinox

Autumn Equinox is the 16th solar term of the year and the 4th of autumn. On this day, the sun is almost directly above the Earth’s equator, so day and night are of the same length all over the world. As Equinox refers, day and night are roughly the same length on this day, and this solar term bisects autumn. From now on, the days in the northern hemisphere will be shorter and the nights longer, and the temperature will drop day by day.
