In ancient Greece, it was used in astronomy to denote a specific point in the movement of celestial bodies, particularly the sun and the moon. Over time, 'epoch' transitioned into Latin as 'epocha' and retained its association with significant points or moments in time. In English, it came to signify a particular period of time in history or the development of a specific field or system.
