The 2015 Vernal Equinox, which marks the first day of Spring for Northern Hemisphere dwellers, is almost upon us. This is the (one of 2) point(s) in the Earth’s orbit when the tilt of its axis (e.g. the North Pole) is neither pointing toward nor away from the Sun. In this situation, virtually all parts of the Earth receive (approximately) equal amounts of day and night (12 hours each). It’s also the point at which the increasing amount daylight (or night-time in the case of the Autumn Equinox) is at a maximum! Here are a few links if you’d like to learn more about equinoxes:
