Centuries – How to Name Them

A century is a unit of time equal to 100 years. Centuries are named using ordinal numbers, so we might refer to the 3rd century or the sixteenth century. Using this system it would be logical to assume that the first century refers to the earliest recorded time, but this is not the case. 

Traditionally, the first century refers to the first 100 years after the birth of Christ, denoted with the abbreviation A.D. meaning Anno Domini (year of the Lord). Nowadays, this is often replaced with the secular C.E. meaning Common Era. 

Centuries before Christ are denoted with the abbreviation B.C. meaning Before Christ. Today the secular B.C.E. meaning Before Common Era is often used instead.

It is important to understand how to name centuries correctly so that you can place a date in the correct century.
