2026年秋分在9月23日

The autumnal equinox of 2026 will occur on Wednesday, September 23rd, at 12:05 a.m. Coordinated Universal Time, marking the beginning of the fall season astronomically in the Northern Hemisphere. This event takes place when the Sun crosses the celestial equator heading from north to south, resulting in an equal length of day and night worldwide. Afterward, the length of daylight gradually decreases in the north and night lengthens, while the opposite occurs in the Southern Hemisphere. The autumnal equinox is one of the key points in the Sun's annual movement cycle and is linked to the tilt of the Earth's axis.
