Ère vs. âge
In French, 'ère' and 'âge' can both refer to periods of time but are used in slightly different contexts. Understanding the nuances of these terms is key to using them appropriately in French language discussions about history, geology, or significant periods.
Ère
It generally refers to a long and significant period in history often marked by a distinct characteristic or event.
L'ère Mésozoïque est connue pour l'abondance des dinosaures.
(The Mesozoic era is known for the abundance of dinosaurs.)
Nous vivons actuellement dans l'ère numérique.
(We are currently living in the digital age.)
Âge
It can refer to various spans of time ranging from historical periods to the life stages of an individual.
L'âge de pierre était caractérisé par la fabrication et l'utilisation d'outils en pierre.
(The Stone Age was characterized by the making and use of stone tools.)
Mon grand-père est dans l'âge d'or de sa vie.

Summary
'Ère' typically denotes a significant historical or geological period, often defined by paradigm shifts or major events. 'Âge', although sometimes used similarly for epochs in history like the 'Ice Age' (l'âge de glace), it also can denote stages of human life or quality periods within culture and development. Both words describe periods marked by significant features or events but differ in their scope and common usage.
