Equinox (Latin: aequus, equal + nox, night) refers to a moment when the Sun is perpendicular to the Equator of the Earth, and the Northern and Southern Hemispheres are equally illuminated; this occurs twice a year, first, around the 20th of March with the Sun progressing northward, as the Spring or vernal equinox in the Northern Hemisphere and the Fall or autumnal equinox in the Southern, and around the 22th of September, with the Sun proceeding southward, as the autumnal equinox of the Northern, and the vernal equinox of the Southern.
- When the equinox entered Pisces, the Savior of the World "appeared as the Fisher of Men."
- The number of the dead long exceedeth all that shall live. The night of time far surpasseth the day, and who knows when was the Æquinox? Every hour adds unto that current arithmetick, which scarce stands one moment.
- Thomas Browne, in Hydriotaphia, Urn Burial (1658)
- At the equinox when the earth was veiled in a late rain, wreathed with wet poppies, waiting spring
The ocean swelled for a far storm and beat its boundary, the ground-swell shook the beds of granite.
- Robinson Jeffers, in "Continent's End" in Tamar and Other Poems (1924)
