The word 'revolution' first brings to mind violent upheavals in the state, but ideas of revolution in science, and of political revolution, are almost coeval. The word once meant only a revolving, a circular return to an origin, as when we speak of revolutions per minute or the revolution of the planets about the sun.

'Coeval' is well-suited for discussions about history or scientifically dated events.

It's less common to use 'coeval' about the present; instead, it's mostly used in historical or academic contexts.

Age or Date

'Coeval' can compare people or things highlighting that they share the same historical period or birth year.
