year-round
Synonym discussion
Sense: adjective/1
'Year-round' describes something that lasts or operates through a full calendar year without breaks for particular seasons. 'Perpetual' is stronger and more formal — it suggests something that never ends at all (a perpetual source of conflict), not just across one year. 'Non-seasonal' is a narrower, more technical term used mainly in business or economics (non-seasonal demand, non-seasonal employment). 'Everlasting' carries a poetic or spiritual tone (everlasting love) and is rarely used for concrete schedules or operations. Use 'year-round' when you mean 'through all four seasons of a normal year' — for example, a year-round school calendar or year-round access to a hiking trail.

Etymology
Formed by combining 'year' (from Old English 'gēar') with 'round' (from Old French 'rond', meaning circular or throughout). The compound has been used since the 1800s to mean 'throughout the entire year', modeled on the earlier 'all year round'.
