Understanding the Concept of Centuries
What Is a Century?
A century is a period of 100 years. The term originates from the Latin word "centum," meaning "hundred." In most modern contexts, centuries are counted starting from the year 1 AD (Anno Domini), which marks the traditionally recognized beginning of the Gregorian calendar.
How Are Centuries Calculated?
Centuries are numbered sequentially, beginning with the 1st century, which includes the years 1 through 100. The 2nd century covers the years 101 to 200, and so on. This system means that:
- The 1st century spans from 1 AD to 100 AD.
- The 2nd century spans from 101 AD to 200 AD.
- The 21st century spans from 2001 to 2100.
- The 22nd century will span from 2101 to 2200.
It's important to note that there was no "year zero" in the Gregorian calendar; the calendar jumps from 1 BC directly to 1 AD.
When Does the 22nd Century Begin and End?
Start Date of the 22nd Century
The 22nd century begins on January 1, 2101. This is because the 21st century covers the years 2001 through 2100, and the next century starts immediately after.
End Date of the 22nd Century
The 22nd century ends on December 31, 2200. The following century, the 23rd century, then begins on January 1, 2201.

Common Questions About the 22nd Century
Is the 22nd Century the 2100s?
No. The 2100s refer to the years 2100 through 2199, which are part of the 21st century. The 22nd century is a different period entirely, from 2101 to 2200.
Why Do Some People Get Confused About Century Dates?
