The word aeon, also spelled eon or æon, originally means "life", and/or "being", though it then tended to mean "age", "forever" or "for eternity". In Homer it typically refers to life or lifespan. Its latest meaning is more or less similar to the Sanskrit word kalpa and Hebrew word olam. A cognate Latin word aevum or aeuum for "age" is present in words such as longevity and mediæval.

Although the term aeon may be used in reference to a period of a billion years (especially in geology, cosmology or astronomy), its more common usage is for any long, indefinite, period of time.

Roger Penrose uses the word aeon to describe the period between successive and cyclic big bangs within the context of conformal cyclic cosmology. In this theory, the remote future of the previous aeons becomes the Big Bang of the current aeon
