Year 260 (CCLX) was a leap year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Saecularis and Donatus (or, less frequently, year 1013 Ab urbe condita). The denomination 260 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.
