Yes, the year 0001 did exist. It marks the beginning of the Anno Domini (AD) calendar era, also known as the Common Era (CE). This system, introduced by the monk Dionysius Exiguus, is used in the Gregorian and Julian calendars. The year 0001 follows the year 1 B.C., and there is no year zero.

FAQs & Answers
