Etymology

PIE word *nókʷts From Middle English equinox, equinoxe, equynox (“one of the two periods in the year when the day and night are of equal length, equinox; either the zodiac sign Aries or Libra, in which the sun crosses the celestial equator”), from Old French equinoce, equinoxe (modern French équinoxe), or from its etymon Medieval Latin ēquinoxium, ēquinoctium, from Latin aequinoctium (“equinox”), from aequus (“equal”) + nox (“night”) (ultimately derived from Proto-Indo-European *nókʷts (“night”)) + -ium (suffix forming abstract nouns). The Latin word, ultimately adopted in Middle English and modern English, displaced Old English efnniht (modern English evennight). The rare alternative plural form equinoctes treats equinox as if it were a Latin word; the plural of Latin nox (“night”) is noctēs.

Meanings

One of two times in the year (one in March and the other in September) when the length of the day and the night are equal, which occurs when the sun is directly overhead at the equator; this marks the beginning of spring in one hemisphere and autumn in the other.
- [H]e [Milton] believed, his poetic vein only flowed from the autumnal to the vernal equinox; and, in his essay on Education, he doubts whether, in the fine days of spring, any study can be accomplished by young men. (Can we date this quote?), Ralph Waldo Emerson, “Milton”, in The Natural History of the Intellect (Emerson’s Complete Works; XII), Riverside edition, London: The Waverley Book Company, published 1893, →OCLC, page 155:
- The word equinox is generally taken to refer to the days when, at every point on the earth, day and night are of equal length. But this definition of the equinox is a bit misleading. Since it gets light before the sun rises and remains light after the sun sets, the actual period of darkness at the equinox will be substantially less than twelve hours, the exact amount depending on latitude and how one defines the boundary between twilight and night. […] In practice, one cannot determine the equinox by measuring the length of time between sunrise and sunset. 2005, Clive [L. N.] Ruggles, “Equinoxes”, in Ancient Astronomy: An Encyclopedia of Cosmologies and Myth, Santa Barbara, Calif.: ABC-CLIO, →ISBN, page 148:
- 21. Report the experiments, if conveniently they may, at both the solstices and equinoctes. / 22. Observe accurately the time of the sun’s rising on the top of the hill and below, and note the difference. 1848, Charles Richard Weld, chapter V, in A History of the Royal Society, with Memoirs of the Presidents.

- For [Julius] Cæsar says, that on the night of the fourth day after his landing there was a full moon. He had before mentioned that the summer was far spent, and the æquinox not come, hence, the full moon must have been either in July or August. 1854, John Williams, “Pro-consul. b.c. 55.”, in The Life of Julius Cæsar, London; New York, N.Y.: G[eorge] Routledge & Co., […], →OCLC, page 195:
- […] Midsummer’s Day falls near the beginning of summer meteorologically, but was the midpoint of summer in the traditional calendar. Though Midsummer’s Day celebrations are common in the modern Celtic countries, there is no evidence that the ancient Celts celebrated either the solstices or the equinoctes. 2006, John T. Koch, “calendar, Celtic”, in Celtic Culture: A Historical Encyclopedia, volume I, Santa Barbara, Calif.: ABC-CLIO, →ISBN, §4 (The Seasons), page 332, column 1:
- Live long, nor feel in head or chest / Our changeful equinoxes, / Till mellow Death, like some late guest, / Shall call thee from the boxes. 1842, Alfred Tennyson, “Will Waterproof’s Lyrical Monologue”, in Poems. […], volume II, London: Edward Moxon, […], →OCLC, page 194:
