calm and peaceful; golden age

Halcyon describes a period of time that was idyllically happy, calm, and peaceful — often looked back on with nostalgia. It evokes golden days of tranquillity, prosperity, and carefree contentment, usually set in contrast to a more troubled present.

The word is almost always used to describe the past — "halcyon days" is its most common form. It carries a bittersweet quality: the calm and happiness it describes are remembered precisely because they have ended. Halcyon can also simply mean calm and peaceful, especially when describing weather or seas.

Etymology of Halcyon

From Greek halkyon (kingfisher bird).

The word evolved from describing literal calm seas to any period of peace and happiness.
