first recorded 19th c. disputed origin

Attested since 1876 or perhaps earlier, the phrase is thought to refer to the notable longevity of the animal. A second theory suggests the expression is a product of rhyming slang, derived from the phrase donkey's ears, which served as a substitute for years before being shortened and its literal sense discarded. As noted by wordhistories.net in 2016, the origins remain uncertain, leaving the longevity of the donkey and the length of its ears as competing explanations for the passage of time.
