Echinocțiul de toamnă: La ce dată începe toamna astronomică și când ziua devine mai scurtă decât noaptea • Știri Brașov Biz Brasov

The autumn equinox in 2026 occurs on September 23 at 03:05 AM in Romania, marking the start of astronomical autumn. This event signifies the transition from summer to autumn, with day and night durations becoming nearly equal. The equinox date varies yearly, typically falling on September 22 or 23 due to the differences between the calendar year and the astronomical year. The phenomenon is linked to the Earth's axial tilt, affecting sunlight distribution. After the equinox, nights grow longer than days in the northern hemisphere, while spring begins in the southern hemisphere. The autumn season lasts until the winter solstice on December 21, 2026.
