Who Decided It Was Year 1? The Surprising History of Our Calendar

Have you ever wondered who decided that our calendar should begin with Year 1? In this video, we explore the fascinating history behind the way we measure time. From the chaotic Roman calendars before Julius Caesar, to the introduction of leap years in the Julian calendar, to Pope Gregory XIII's reforms that gave us the Gregorian calendar we use today, the story is far more complex than most people realize. You'll discover: • How Julius Caesar fixed the Roman calendar • Why Pope Gregory XIII replaced the Julian calendar • Where the names of the days of the week come from • Who created the A.D. dating system • Why there is no Year 0 • Why historians believe the traditional date of Jesus' birth may actually be several years off • How different cultures established their own versions of "Year 1" The modern calendar isn't simply a neutral way of tracking time—it's a blend of astronomy, religion, politics, and history that continues to shape our daily lives.
