Spring officially begins in the Northern Hemisphere on March 20 with the vernal equinox as the entire world experiences an equal day and night.For ease of recordkeeping, meteorologists and climatologists consider March 1 the first day of spring, but astronomically speaking, the Earth’s equator is aligned directly with the sun on the vernal equinox. In 2022, that occurs March 20 at 11:33 a.m. Eastern time.Astronomical seasons are based on the position of the Earth with respect to the sun as the planet makes its annual revolution around this closest star.
