EQUINOX - The Astronomical Event

Twice a year, on the Equinoxes around 21st of March and 21st of September, day and night are equally long: roughly 12 hours each.
In the northern hemisphere, the vernal equinox marks spring and the autumnal equinox marks - right - autumn. Along with the summer and winter solstices, the two equinoxes mark the change in seasons.

These four dates are also important for climate analyses, they represent typical solar angles and sun path patterns for each place on earth.
Since we consider bioclimatic design essential and love the symbolic strength of equal 50/50, we chose our name after this wonderful astronomical event.
