i'm 29 years old and speak perfect english and the word "epoch" is practically foreign to me. they should replace it with something like "era" that is more common in everyday use. i realize it is easier to relate to "la época" but it's really odd choice of word to me.
Wikipedia gives the following SIX possible uses of the word epoch as relating to a certain span of time.
Epoch (reference date), a moment in time chosen as the origin of a particular era Epoch (geology) or geologic epoch, a span of time smaller than a "period" and larger than an "age" Epoch (cosmology) or cosmologic epoch, a phase in the development of the universe since the Big Bang Epoch (astronomy), a moment in time used as a reference for the orbital elements of a celestial body Epoch (race), racial periods in Blavatsky's esoteric theory of the root races Epoch, a step in the training process of an artificial neural network
