Overview

  • National observatories set the moment for Friday, March 20, at 15:46 in peninsular Spain and 08:45 in Mexico’s central time.
  • The equinox occurs when the Sun crosses the celestial equator, bringing nearly equal day and night across the Northern Hemisphere.
  • Spring 2026 will last about 92 days and 18 hours, ending on June 21 at the summer solstice.
  • Daylight will grow by roughly three to four minutes per day after the equinox, accumulating until late June.
