Solstices & Equinoxes
The seasons begin as the sun reaches a solstice or an equinox.
Solstices are the times when the sun appears farthest north
(summer) or south (winter) of a projection of Earth's equator
into space. Equinoxes are the times when the sun crosses
the plane of Earth's equator from south to north (spring)
or north to south (autumn). These dates vary a little from
year to year.
