    In Aries twelve degrees or more had run. Dryden.

    The one as long as th’ other. William Shakespeare, Othello.

    No more than usual equinoxes blew. Dryden.

Freebase

  1. Equinox

    An equinox occurs twice a year, when the tilt of the Earth's axis is inclined neither away from nor towards the Sun, the center of the Sun being in the same plane as the Earth's equator. The term equinox can also be used in a broader sense, meaning the date when such a passage happens. The name "equinox" is derived from the Latin aequus and nox, because around the equinox, night and day are about equal length. At an equinox the Sun is at one of two opposite points on the celestial sphere where the celestial equator and ecliptic intersect. These points of intersection are called equinoctial points: classically, the vernal point and the autumnal point. By extension, the term equinox may denote an equinoctial point. The equinoxes are the only times when the subsolar point is on the Equator. The subsolar point crosses the Equator moving northward at the March equinox and moving southward at the September equinox.
