Spring 2026 is set to officially commence on March 20, coinciding with the spring equinox. This astronomical event marks the moment when the sun shines directly on the equator, resulting in nearly equal day and night lengths across the globe. However, the symbolic start to spring was arguably signaled earlier by Groundhog Day on March 16, where Punxsutawney Phil, the famed groundhog, predicted six more weeks of winter.
