What does the autumnal equinox mean

Interpretation: One of the 24 solar terms in the lunar calendar, it means that autumn has officially entered.

The ancient Chinese book “Spring and Autumn Dew, Yin and Yang in and out of the upper and lower sections” said: “The autumn equinox, Yin and Yang phase half also, so day and night are cold and summer.” The autumnal equinox means “half”. “Autumn Equinox” means that according to the ancient Chinese to spring, summer, autumn, winter as the beginning of the season division, the autumn equinox day in the autumn 90 days, equal autumn.

The meaning of the Autumnal Equinox “The seventy-second Hou of the Moon” : “In August… See the Spring equinox.” “Equinox” indicates the equalization of day and night. Like the vernal equinox, the sun shines directly on the Earth’s equator on this day, and day and night are equal. Since then, the position of direct sunlight has moved further south, the northern Hemisphere has gradually become shorter days and longer nights, and the temperature has decreased, which has universal significance in the country.

After the autumnal equinox, days get shorter and nights get longer in the northern Hemisphere, and days get longer and nights get shorter in the southern hemisphere.

From the winter solstice the days get longer, but from the spring equinox the days get longer than the night, from the summer solstice the days get shorter, but from the autumn equinox the days get shorter than the night.
