Age
From A Wheel of Time Wiki
An age is a very long period of time. Ages are typically homogenous, with beginnings and endings marked by dramatic changes and events.
There are seven ages, each one corresponding to one of the seven spokes on the Wheel of Time. They do not seem to have any particular length, though all are thousands of years long. There is some evidence in the books that we are living in the First Age, for example real-world references.
