The phrase “halcyon days” refers to a period of peace, happiness, and prosperity — often looked back on with nostalgia. It can also literally denote a stretch of calm, mild winter weather.
The term comes from Greek mythology. Alcyone (or Halcyone), daughter of Aeolus, the god of winds, was transformed into a kingfisher (the halcyon bird) after she and her husband drowned at sea. Moved by her grief, Aeolus calmed the winds and waves for fourteen days around the winter solstice each year so she could nest safely on the waters. These tranquil days became known as “halcyon days.” The expression passed into Latin, then into English by the 16th century.
The phrase captures a blend of tranquility, warmth, and emotional stillness so well.
