The decade from 1960 to 1969, or the years of a person's life from 60 to 69.
From 'sixty' plus plural suffix, from Old English 'siextig'. The cultural significance of 'the Sixties' as a revolutionary decade emerged during that period itself.
When we say 'the Sixties,' we're not just naming a decade but invoking an entire worldview - those ten years became so culturally explosive that the mere mention of the time period conjures images of transformation and rebellion.
