The Spring Equinox, or Vernal Equinox to some, marks the beginning of spring in the Northern Hemisphere each year. The Spring Equinox occurs at the same moment across the globe, even though clocks reflect a difference in time, depending on time zone. The Vernal Equinox marks the passages of the sun across the celestial equator as it travels north along the ecliptic, making day and night approximately equal across the world. Source: Almanac.com
The March equinox or Northward equinox is the equinox on the Earth when the subsolar point appears to leave the southern hemisphere and cross the celestial equator, heading northward as seen from Earth.
