AD 40

AD 40 (XL) was a leap year starting on Friday of the Julian calendar. At the time, it was known as the Year of the Consulship of Augustus without colleague. The denomination AD 40 for this year has been used since the Early Middle Ages, when the Anno Domini calendar era became the prevalent method in Europe for naming years. ^{Gnaeus Julius Agricola, Roman general (d. 93)}
