Eternity is an English word name meaning "endless time" or "everlasting life", from the Latin aeternitas. Calvin Klein's perfume Eternity, launched in 1988, made the word feel like a name, and it belongs with Destiny, Serenity and Trinity among the virtue-style names that rose in the 1990s and 2000s. Eternity peaked at number 1974 in 2021 and ranks number 2305 in 2025.
