Summary (tl;dr)

Today, March 20, 2026, marks the astronomical first day of spring in the Northern Hemisphere, known as the Spring Equinox, driving a surge in online searches related to its timing and significance.

Essential Background

The Earth experiences seasons due to its axial tilt relative to its orbit around the Sun. The first day of astronomical spring is defined by the vernal or spring equinox, an event that typically occurs on March 19, 20, or 21 each year in the Northern Hemisphere. During an equinox, the Sun crosses the celestial equator, resulting in nearly equal periods of daylight and darkness across most of the globe. While meteorological spring began earlier on March 1, based on temperature patterns, astronomical spring is determined by the Earth's position relative to the Sun.
