in gif diehard is a Christmas movie. There is no right or wrong answer. But is White Hat right or wrong? 19:00, 1 January 2020 (UTC)

Both. It's the only way to settle this. 19:13, 1 January 2020 (UTC)
I think that he is right, but it’s like asking if diehard is a Christmas movie. There is no right or wrong answer.
Indeed, famed D.J. and space journalist Scott Manley says it's a new decade in C but not in FORTRAN. 19:37, 1 January 2020 (UTC)
You mean it's already 21th century for FORTRAN? -- Hkmaly (talk) 23:33, 1 January 2020 (UTC)
But what decade is it in the Delisle scale? 20:35, 1 January 2020 (UTC)

I'm fairly certain Ponytail contradicts herself in panel 5. Arguing that decades are not cardinally numbered is arguing that the decade starts in 2021 (ordinal numbering.) 21:20, 1 January 2020 (UTC)

She doesn't: you're assuming there are only two options, but that's not the case. Decades (in the common "20s, 30s, 40s" form) are not technically numbered at all: they're named, it's just that those names are based on numbers.
It's still a sequence, like names or dictionary entries being grouped into "As, Bs, Cs" and so on, though. (Is there a specific name for this type of sequence? If so, I don't know it.) 23:03, 1 January 2020 (UTC)
She (more likely Randall's slip of the pen) is still wrong: what she means is that they aren't ordinally numbered, which is the reason the other guy is wrong. 08:23, 2 January 2020 (UTC)

Having had this conversation on WhatsApp, I have settled on an ingenious solution that works for me (on being told that "0" had not been invented in the year between -1 and +1") and explains why decades start with "10, 20...": As usually nowadays, the first decade was the Betaversion and so only ran from 1-9...

Nobody really recognised the possibility of having/not having 0AD until c.525AD, anyway. (Sitting betwixt the nominal start of what became in our zero in 5thC and its eventual formalising in 7thC, over in India/etc.) If you ask me (and you aren't doing, I know!) I think they probably were envisaging an early version of 1s' Compliment, but knew it would be silly to have two separate numbers for the year ±0 and so fudged it entirely the other way. ;) 11:37, 2 January 2020 (UTC)

Every year is a new decade. Just some of them overlap. The 203rd decade was from 2021 to 2030, while the '20s will run from 1920 to 1929. Both are legitimate decades. So id 1994-2003; it just doesn't have a convenient name to refer to it by. Heck, you don't even need a new year. 1981-12-03 to 1991-12-02 is the first decade of my life :) So if you want to celebrate the start of a new decade, you should celebrate every single day.

By that logic, the 203rd decade started 203 planck lengths (or other smaller time units) after the big bang. Or was it 202 planck lenghts after? However I agree, that decades start and end all the time. The question is just, what day does the decade "the 20s" start. I'd say it started on January 1, 2020. --Lupo (talk) 11:23, 2 January 2020 (UTC)
