Meaning
A remembered period of happiness, prosperity, calm, or ideal conditions, almost always invoked retrospectively ('the halcyon days of something'). In older and more literal use, a spell of calm settled weather around the winter solstice, and meteorological writers still use it that way. Literary and nostalgic; virtually always retrospective, with a hint that the good times are gone. Regional use: General English (literary register).
Origin
From Greek alkuon, kingfisher; the breathing 'h' in the English spelling reflects an ancient folk etymology that tied the word to hals (sea) and kyon (conceiving), though scholars regard the real origin as an unexplained loanword. In myth, Alcyone, daughter of Aeolus, was widowed and drowned herself, and she and her husband were transformed into kingfishers; the bird was believed to breed in a nest floating on the sea at the winter solstice, charming wind and waves into stillness. Pliny the Elder fixed the calm spell at seven days either side of the solstice, giving Greek alkuonides hemerai and Latin alcyonei dies, 'kingfisher days'. English adopted halcyon as a poetic name for the kingfisher in the late 14th century, and Etymonline dates 'halcyon dayes', in the calm-weather sense, to the 1540s as a translation of the Latin phrase; Shakespeare had already extended it figuratively in King Henry VI, Part 1 (c. 1591), 'Saint Martin's summer, halcyon days'. Zoologist D'Arcy Thompson noted in 1895 that real kingfishers do not nest at sea and speculated the myth may encode an astronomical phenomenon instead.
