What BC and AD Stand For

Understanding where BC and AD came from and why they’re used can help make their meanings clear. Together, they form what is known as the Christian Era.

BC Abbreviation Meaning

The abbreviation BC stands for “Before Christ.” It refers to all time before the theoretical birth of Jesus Christ.

AD Abbreviation Meaning

The abbreviation AD stands for “Anno Domini” in Latin. In English, this means “in the year of our Lord.” This abbreviation refers to all time after the theoretical birth of Jesus Christ.

History of BC and AD Abbreviations

An Italian monk named Dionysius Exiguus is believed to be the person who came up with BC and AD, or the Christian Era, in the AD 500s sometime after AD 525. These abbreviations and this method of calculating time came out of an argument about how to calculate Easter.

Dionysius calculated the birth of Christ as being in the year 753 AUC (ab urbe condita, Latin for “from the foundation of the city of Rome”). He then made the year Christ was born AD 1 and all time before that started from 1 BC. Although his calculations have been questioned for centuries, Dionysius’ system has stuck. It gained widespread use in the 11th century.

Modern Use of BC and AD

BC and AD are still commonly used around the world as time designations because they are habitual and the accepted abbreviations of Christians. Scholarly guidelines from the 21st century encourage the use of BCE and CE over BC and AD because the newer abbreviations are more inclusive.

BC and AD Timelines

AD time starts when BC time ends, but there is no year 0. So, BC starts in the year 1 BC and AD starts in the year AD 1.

BCE and CE History

Historians and scholars who were not Christians used the BCE and CE abbreviations to communicate with religious groups about history. The BCE era is exactly equivalent to the BC era and the CE era is exactly equivalent to the AD era to respect religious beliefs, yet make history inclusive.

BCE Abbreviation Meaning

The abbreviation BCE stands for “Before the Common Era.” This refers to all time before the theoretical birth of Christ. For some, BC is now called BCE, but they refer to the same timeframe.

CE Abbreviation Meaning

The abbreviation CE stands for “Common Era.” This refers to all time after the theoretical birth of Christ. For some, AD is now called CE, but they refer to the same time.

Proper Use of BCE and CE

The abbreviations BCE and CE are generally written without any periods between the letters, so not B.C.E. or C.E. The letters BCE and CE go after the year when you are writing a date.

AD or A.D. stands for Anno Domini and is a label for numbering years after Christ was born. BC or B.C. means Before Christ. The year Christ was born is considered AD 1 and the year before that is labeled 1 BC. Historians use a nomenclature with less religious connotation: namely CE/BCE where CE means "Common Era" and BCE stands for Before Common Era. Although the labels used are different, BC and BCE are the same and so are AD and CE. This system of numbering years was invented by Dionysius Exiguus in AD 525 and is used in the Julian and Gregorian calendars.

This special £5 coin was made in 1999, before the turn of the century (from the 20th to 21st centuries / AD 1999 - 2000). On one side it marks GMT (Greenwich Mean Time) with the line going through Greenwich.

What is A.D.?

AD stands for Anno Domini, which is Latin for "Year of our Lord," and is used to number years in the Julian and Gregorian calendars. AD denotes the calendar era after the birth of Jesus Christ. The traditionally accepted year of Christ's birth is labeled AD 1 and the year before is 1 BC. This calendaring system was devised in AD 525, but was not widely used until after AD 800. An alternative for AD is CE, which stands for Common Era, Christian Era or Current Era.

What is B.C.?

B.C. stands for Before Christ, and it means the number of years before the time of Jesus Christ. The use of B.C. is believed to originate with Bede in the 8th century (AD). The Latin version is "ante vero incarnationis dominicae tempus" ("the time before the Lord's true incarnation"), equivalent to the English term "before Christ" which was used by Dionysius Exiguus.

Numbering scheme

In the Common Era (CE or AD), the years are numbered in chronological order i.e. the year AD 401 followed the year AD 400. However, in the BC or BCE era, the years are numbered in the reverse order i.e. the year 300 BC followed the year 301 BC.

Did you know?

  • The Hebrew calendar considers the year 3760 BC as year 1.
  • In the Islamic calendar, the year 622 AD is year 1 because Prophet Mohammed embarked on a holy journey in that year.
  • Buddha died over 400 years before Christ was born.
  • While AD 1 is when Christ was believed to have been born when this system was invented, historians now believe that Christ was actually born between 7 BC and 4 BC.
