NOTOC Year 504 (DIV) was a leap year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Nicomachus without colleague (or, less frequently, '*year 1257 *Ab urbe condita'''''). The denomination 504 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.
