The birth of Jesus (pictured above) is widely regarded to have been placed by Dionysus Exiguus, inventor of the Anno Domini dating system, in 1 BC. Modern scholarship, however, regards the birth of Christ to have taken place between 6 and 4 BC.

Year 1 BC was a common year starting on Friday or Saturday in the Julian calendar (the sources differ; see leap year error for further information) and a leap year starting on Thursday in the proleptic Julian calendar. It was also a leap year starting on Saturday in the Proleptic Gregorian calendar. At the time, it was known as the Year of the Consulship of Lentulus and Piso (or, less frequently, year 753 Ab urbe condita). The denomination 1 BC 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. The following year is AD 1 in the widely used Julian calendar and the proleptic Gregorian calendar, neither of which have a "year zero".
