Almost. it’s the 21st day of the 22nd year... 2000 was year 1.

I regret to inform you that in the Gregorian tradition you are incorrect. If you are referring to some other tradition, please provide further explanation.

Trolling, are you?

Apparently, pointing out facts is now trolling..

No, there was a pretty big discussion about 0 and 1 index ranges on HN yesterday.

The year the new century started on was part of the discussion. People are still debating as to whether the century started in 2000 or 2001.

Sorry, I should have been more clear. In 2000 there was a big debate over whether that was the first year of the new century. I sincerely thought that it had been settled long ago. Year 0 never existed (Christ is conventionally born on year 1 [1]), and the first hundred years (first century) go from 1 to 100. The second hundred years (second century) begin in 101, and so on.

I thought HN likes zero based indices? 2000 would be the zeroth year.

One definition of "first" is "preceding all others" [0], so something with an index of 0 would still be the first item.

Apparently the definition of "zeroth" is "being numbered 0 in a series" [1], so something with an index of 0 could be both the "first" and the "zeroth" item...

However, another definition of "first" is "one that is number one in a series", so the headline of this post is both accurate and inaccurate, depending on which definition you want to use, I suppose.
