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.

Is it? The first century spanned year 1 to 100 (there was no year zero). So the XX00 year is considered to be part of the preceding century. Thus 2021 is indeed the 21st year of the 21st century.

If 2000 is part of the previous century, was 2001 actually the true start of the new millennium?

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.
