Answer: Tuesday, March 20, at 12:15 PM Eastern Time. Winter will be gone and spring officially welcomed in the Northern Hemisphere when the vernal equinox of 2018 happens on Tuesday, March 20, at 12:15 PM Eastern Time. Two equinoxes occur each year in March and September. This is the time when the sun shines directly on the equator, causing day and night to be nearly equal in length. The spring equinox, or vernal equinox, happens each year on March 19, 20 or 21. Source: TimeandDate.com




The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth’s North pole.
