Once again, Maeve presents contradictory and also incorrect information in an article. Amazing exactly how someone v so tiny actual knowledge of the English language deserve to pretend come be together an authority.
An epoch is not generally thought about to it is in a longer period of time than an era.

These room not the geological definitions, however the generally-accepted supplies for day-to-day English.Maeveon February 22, 2012 12:21 pm

An aeon is precisely 1,000,000,000 years, simply as an date is a measure of time because that a specific event. Such as the ‘Thirty Year War’, or when Queen Elizabeth climbed to power. I think neither of you space incorrect, due to the fact that both meanings coincide in ~ the meaning of the word. It’s simply a subjective manner in which the writer chooses to usage the word.Davidon July 16, 2017 9:22 pm
Why has this post still no been revised? it is usual knowledge the an Era is longer than an epoch as an date is a subdivision of an Era. You need to clarify that an date may, in ~ times, exceed the size of an Era however generally speak is not thought about to.Dale A. Woodon October 17, 2017 3:33 pm
Era, Epoch, and Eon — Duh?Since Queen Elizabeth ns was mentioned, her time is referred to as “the Elizabethan Age”.
