“Equal Night”

21 Mar

I’d say I’m looking forward to less rain, warmer temperatures, and a return to regular cycling mileage.  In the Bay Area, however, this may be wishful thinking.  In any case, the vernal equinox has passed, and whether we can tell or not, spring is here.  If nothing else, now following “equal night,” daylight will once again exceed nightfall.

“The March equinox is the movement when the sun crosses the true celestial equator – or the line in the sky above the earth’s equator – from south to north, around March 20 (or March 21) of each year. At that time, day and night are balanced to nearly 12 hours each all over the world and the earth’s axis of rotation is perpendicular to the line connecting the centers of the earth and the sun.”  (timeanddate.com)
