Time to watch the movie 21 at that time?

Isn't this the 22nd year of the 21st century? :)

Technically the 21st century began 1/1/2001

You are right. I remembered the new century/millennium celebrations in the year 2000, and based my comment on that.

Changed the title a little, hard to get it right :)

It's definitely 21st year of 21st century. 2001 was 1st year, not 0th :)

Also of note, 2021-01-21 20:21:01 (202-101-21-202-101)

Or 2021-01-21 21:11 (202-101-212-111), etc, etc

Brilliant. something to think about how far we have come

Without the 21st month it is meaningless

May 21st is on the 20th week of the year. So close...

Loving it!
