I don't have enough context to write an accurate overview of "764." While you've indicated the context is "year," I cannot determine whether 764 refers to a specific historical year, an event that occurred in 764 CE, or something else entirely without additional information.

The denomination 764 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
