Eon and era. In general, an eon is a very long time, comparable to the age of the universe. An epoch is a fixed point in time (like the zero date of a calendar, or the moment a world-changing event occurred), especially one that marks the beginning of a new era. One can “make an epoch” by doing something that changes things forever.
