The sixties refers to the 1960s, the decade from 1960 to 1969, a period of dramatic social and cultural change in America and around the world. During the sixties, young people questioned traditional ways of doing things, new styles of music like rock became wildly popular, and movements for civil rights and equal treatment gained momentum. The decade saw the first humans land on the moon in 1969.

The sixties brought major changes in fashion, music, and attitudes. The Beatles and other musicians created sounds that felt revolutionary. Television became central to American life, bringing news and entertainment into living rooms across the country. The decade also saw important advances in civil rights, with new laws protecting equal treatment regardless of race.

When someone describes something as having a sixties vibe or sixties style, they usually mean it has a colorful, optimistic, or unconventional quality associated with that era. You might see sixties fashion featuring bright colors, bold patterns, and experimental designs.

People also use “sixties” to describe someone's age: when your grandparents are in their sixties, they're between 60 and 69 years old.
