What is a Century?
A century is a period of 100 years. Centuries are numbered ordinally in English (e.g., the “1st Century”, the “21st Century”). The system we use to track years is based on the Gregorian calendar, which counts forward from the estimated birth year of Jesus Christ (AD/CE).
How are Centuries Calculated?
Because there was no “Year Zero” in the Gregorian calendar, the 1st Century started in the year 1 and ended in the year 100. Following this strict mathematical rule, every century begins with a year ending in “01” and ends with a year ending in “00”.

What century are we currently in?
