when is the 22nd century

The 22nd century runs from 1 January 2101 to 31 December 2200 in the Gregorian calendar.

Quick Scoop: When is the 22nd century?

• It begins on 1 January 2101.

• It ends on 31 December 2200.

• We’re currently in the 21st century, which runs from 2001 to 2100.

Why not 2100?

Centuries are counted starting from year 1, not year 0, because the Gregorian calendar has no year 0; it goes directly from 1 BC to AD 1.

That means:

• 1st century: years 1–100
• 2nd century: years 101–200
• …so the 21st century is 2001–2100, and the 22nd century is 2101–2200.

A simple way to remember

Take the century number (22), subtract 1 (21), and add “01” for the start and “00” for the end:

• Start: 2101
• End: 2200

So if you’re wondering “when is the 22nd century?” — it’s the period from 2101 to 2200.

TL;DR: The 22nd century is 2101–2200, not starting in 2100.
