📝 About Autumn Equinox 2026
Around September 22-23, the Sun crosses the celestial equator heading southward, producing roughly equal day and night in the Northern Hemisphere and signaling the astronomical start of autumn. The autumnal equinox held deep significance for agricultural societies, marking the completion of the harvest and the need to prepare food stores for winter. In China, the Mid-Autumn Festival typically falls near this date, celebrating the harvest moon with mooncakes and family reunions. The Harvest Moon — the full moon nearest the equinox — rises at nearly the same time for several consecutive nights, historically giving farmers extra evening light to complete their harvest work.
