The Spring Equinox

The date of the Vernal Equinox and of astronomical spring in the northern hemisphere (the official start of spring) falls on March 20th this year.  This is when the Sun's path (‘the ecliptic’) first crosses the celestial equator on its apparent journey northwards into the sky.  The orientation of the Earth at the spring or autumnal equinox is such that neither of Earth’s poles are inclined toward the Sun and all locations experience equal hours of daylight and darkness; hence the term equinox.
