Counting the Years: How the Calendar Reflects Jesus’ Birth

Our everyday calendars hold a hidden Christian symbol – the birth of Jesus Christ. While the exact date of Jesus' birth remains unknown, the most widely used calendar system, the Gregorian calendar, uses it as a reference point.

A.D. and B.C.: A Timeline of Years

The letters A.D. stand for "Anno Domini," which translates to "In the year of the Lord." This designation marks the years following what is believed to be the year Jesus was born. Years before his birth are denoted as B.C., meaning "Before Christ."

It's interesting to note that there is no year zero in this system. So, the year 1 B.C. is directly followed by 1 A.D. This slight inconsistency arose in the 6th century by a monk named Dionysius Exiguus when he devised this dating system.

From Jesus to the Gregorian Calendar

The concept of using Jesus' birth as a reference point for dating wasn't immediate. Early Christians used other calendars,sometimes referencing the creation of the world. However, Dionysius' system gained traction and was eventually incorporated into the Gregorian calendar, established in 1582.

The Reach of a Calendar

The Gregorian calendar's accuracy for pinpointing Jesus' birth is debatable, but its functionality and widespread adoption by European powers made it the dominant system. Today, it's the most used calendar globally, even in non-Christian cultures.

Moving Beyond A.D./B.C.

In recent times, there's been a shift towards more inclusive terminology. Many people now use C.E. (Common Era) for A.D. and B.C.E. (Before the Common Era) to acknowledge the global reach of the calendar without solely referencing a Christian event.

Whether you use A.D. or C.E., the underlying concept remains – our calendars reflect a historical attempt to mark the passage of time using a significant Christian event.
