The Vernal Equinox is the day when the Sun crosses the celestial equator moving north. Equinox means “equal night”, and shows the day when Sunlight is evenly distributed all over the earth. Essentially if you could make the round globe flat, the equinoxes are the days when that flat surface is most perpendicular / flat toward the Sun.
The Vernal Equinox marks the first day of more sunlight in the Northern Hemisphere and Less in the South, for the next 6 months. In the Northern Hemisphere, it is the first day of spring – where new beginnings abound.
