when spring starts

Spring starts on specific dates depending on whether you're using the astronomical or meteorological definition, and it varies by hemisphere. In the Northern Hemisphere, where most queries focus, it's tied to the spring equinox around late March.

Astronomical Spring

This marks the official celestial start when day and night are nearly equal, caused by Earth's tilt aligning the sun over the equator.

• 2026 Date : Friday, March 20, at 10:46 A.M. EDT (14:46 UTC).

• Spring then runs until the summer solstice on June 21.

• Dates shift slightly yearly due to Earth's elliptical orbit; for example, 2027 is March 20 at 4:24 P.M. EDT.

Fun fact: In 2024, it was the earliest in 128 years on March 19—nature's way of keeping us on our toes!

Meteorological Spring

Scientists prefer this fixed calendar-based version for consistent weather tracking and climate data.

• Starts March 1 each year in the Northern Hemisphere, lasting through May.

• Ideal for averages since equinox dates wobble between March 19-21.

• Southern Hemisphere flips it to September 1-December.

Cultural & Trending Views

Folks often blend both—planting gardens by meteorology but celebrating equinox rituals astronomically. Recent forums buzz about 2026's mild UK weather tease right before March 1, sparking "early spring?" debates amid climate shifts.

Globally, spring symbolizes renewal: think blooming lilacs or ancient equinox festivals. In Southern spots like Australia, it's September vibes while we're bundling up.

TL;DR : Northern 2026 astronomical spring hits March 20; meteorological from March 1.
