End of the decade? Yes, dammit

Nineteen years ago, I banged the drum pretty hard that 2000 was not the first year of the 21st Century, because the Christian calendar has no year zero. But yesterday, I disagreed entirely with Sandi Duncan, managing editor of the Farmers' Almanac, during her interview on NPR:

RACHEL MARTIN, HOST: I mean, it feels like a big deal, 2019 to 2020. Why is there such a debate about whether or not this is the end of the decade?

SANDI DUNCAN: You know, it's really interesting. But I hate to tell you it's not.

MARTIN: It's not?

DUNCAN: Actually, no. We ran a story several years ago. In fact, you know, remember the big celebration in 1999. People thought that the new millennial was going to start the next year. But really, a decade begins actually with the year ending in the numeral one. There was never a year zero. So when we started counting time way back when, it goes one through 10. So a decade is 10 years. So in actuality, the next decade won't start until January 1, 2021.

That's such a narrow technical point—I should know, I made the same point in 1999—but it isn't what Martin asked.

Duncan concluded, "I mean, what do you call the decades of the '20s? I guess it's the '20s, but is that the 1920s or the 2020s? So it's one of those fun things that you can argue about until next - the new decade, which starts on January 1, 2021."

We'll call it "the '20s" because, you know, the numbers all have 20 in them.

So, let's clarify. 2000 was the first year of the 2000s but the last year of the 20th century. The 21st century began on 1 January 2001. So 2020 will be the first year of the '20s (duh!) but technically, just technically, it will be the last year of the 202nd decade of the Common Era.

Got that?
