bya or b.y.a. is an abbreviation for "billion years ago". It is commonly used as a unit of time to denote length of time before the present in 109 years. This initialism is often used in the sciences of astronomy, geology, and paleontology. Related units are mya ("million years ago), and byr ("billion years"). These are traditionally written in lowercase. Ga or Gya has a capitalized first letter instead.
