2026 astronomical and seasonal transitions

Overview

The year 2026 features various astronomical and meteorological seasonal transitions. The spring equinox in the Northern Hemisphere is scheduled for March 20, a period of geometric symmetry where the Earth's axis is perpendicular to the Sun's rays, resulting in approximately 12 hours of day and night globally.

Later in the year, the transition to autumn is defined by both meteorological and astronomical systems. Meteorological autumn begins on September 1, while the astronomical autumnal equinox is expected around September 22 or 23. This equinox marks a period where the Earth's axis is not tilted toward or away from the sun, leading to nearly equal daylight and darkness before the Northern Hemisphere experiences decreasing daylight hours until the winter solstice on December 21.
