Background:
An equinox is an astronomical event in which the plane of Earth's
equator passes through the center of the Sun which occurs twice each
year, around 20 March and 23 September. The March equinox is
known as the Vernal Equinox, or, in the northern hemisphere, as the
Spring equinox. The September equinox is known as the Autumnal
equinox, or, in the northern hemisphere, as the Fall equinox.
A Solstice is an astronomical event that occurs twice each year (around
June 21 and December 21) as the Sun reaches its most northerly or
southerly excursion relative to the celestial equator on the celestial
sphere.
The exact time of the equinoxes and solstices can be found here. Please note: The times in this link are Greenwich Mean Time. You must adjust these times to your time zone.
The solstice and equinox rides commemorate these four astronomical events
each year.

50cc Quests on each of the four astronomical events to qualify for the Four Seasons 50cc Quest Award!
You must be riding sometime during the date of the solstice or
equinox. Purists choose to be riding at the exact time of the
solstice or equinox.
