Vernal Equinox Marks Start of Spring in Northern Hemisphere Spring officially begins in the Northern Hemisphere on Friday with the vernal equinox, though the weather may not yet reflect the season’s arrival. The equinox occurs when the sun is directly overhead at the equator, marking the transition from winter to spring in the Northern Hemisphere and from summer to fall in the Southern Hemisphere. During this time, both hemispheres receive nearly equal amounts of sunlight, with day and night lasting almost the same duration. The equinox has been celebrated for centuries across cultures. In Japan, it is observed as a public holiday, while at the ancient Mayan site Chichen Itza in Mexico, the equinox aligns with a unique phenomenon. During the event, sunlight casts a shadow pattern resembling a serpent slithering down the pyramid of El Castillo. Similar traditions exist in other regions, highlighting humanity’s long-standing connection to celestial events. The vernal equinox occurs when Earth’s axial tilt is neither tilted toward nor away from the sun, resulting in balanced sunlight distribution. This contrasts with the solstices, which mark the extremes of Earth’s tilt. The summer solstice, occurring between June 20 and 22, brings the longest day of the year, while the winter solstice, between December 20 and 23, results in the shortest day. For 2026, the vernal equinox falls on March 20 at 10:46 a.m. EST. Following this, days in the Northern Hemisphere gradually lengthen until the summer solstice in June, while days in the Southern Hemisphere shorten. The distinction between meteorological and astronomical seasons further complicates the timing of seasonal changes.#summer_solstice #vernal_equinox #chichen_itzza #el_castillo #winter_solstice
