Spring Equinox 2026: Welcoming Astronomical Spring

Winter is drawing to a close as the Vernal Equinox approaches, marking the official start of astronomical spring in 2026. This year, the first day of spring will arrive on Friday, March 20th.

What is the Vernal Equinox?

The Vernal Equinox occurs when both the northern and southern hemispheres receive equal illumination from the Sun. This happens because the Sun crosses the celestial equator, moving from south to north. Earth’s axial tilt of approximately 23.4 degrees, combined with its orbit around the Sun, causes this shift in the angle of the Sun in our sky.

Timing of the Equinox in 2026

The exact time of the Vernal Equinox varies depending on your time zone:

• 12:16 p.m. NDT
• 11:46 a.m. ADT
• 10:46 a.m. EDT
• 9:46 a.m. CDT
• 8:46 a.m. MDT/CST
• 7:46 a.m. PDT

Astronomical vs. Meteorological Spring

It’s important to distinguish between astronomical and meteorological spring. Astronomical spring, as discussed here, is based on Earth’s position relative to the Sun. Meteorological spring, is based on temperature cycles and is typically defined as March 1st to May 31st.
