According to what years mean. Years are not 0 indexed.
A "decade" of apples would be apple #1 to apple #10
The second "decade" would then be apple #11 to apple #20
Ergo, 2020 is the ending year of the second decade of the third millennium, which started on 2001 :)
It's essentially the difference between celebrating a new chunk of time defined by our collective radix, and celebrating a year because of the way it looks.
We are now in "the 2020s" but not the second decade until next year. Therefore, it is inaccurate to say we are in a new decade.
- benatkin 7y agoThey are zero indexed. The first zero is just missing. It's only relevant if you need to work in terms of the nth century, or cross the boundary between CE and BCE. Calling this the start of a new decade, and 2001 the start of this century, still makes perfect sense with the logical and consistent model that ISO has come up with. https://www.iso.org/obp/ui#iso:std:iso:8601:-1:ed-1:v1:en https://www.iso.org/obp/ui#iso:std:iso:8601:-1:ed-1:v1:en I like ordinals and appreciate the distinction between ordinal and cardinal, and am happy with this edge case. It gets confusing with centuries and terms like the 2000s (https://en.wikipedia.org/wiki/2000s https://en.wikipedia.org/wiki/2000s) but decades tend to always be called 10s, 20s, etc. If you can get people to call this the 202nd decade, more power to you. However, defining the 2020s or 20s as 2021-2030 is wrong.
