Echinocțiul de toamnă 2026: când începe toamna astronomică. Nopțile devin tot mai lungi

The autumn equinox in 2026 will occur on September 23 at 03:05 local time in Romania, marking the start of astronomical autumn in the northern hemisphere. This event signifies the moment when the Sun crosses the celestial equator, resulting in nearly equal day and night lengths. Following the equinox, days will gradually shorten until the winter solstice on December 21, 2026. The equinox does not fall on the same date each year, with variations noted in previous and upcoming years. In Romanian tradition, this period is associated with harvest celebrations and preparations for winter, known as "Țâr înainte – țâr înapoi."
