I think the decade technically ends next year but it is a great shot. Last of the 2010s.

u/thiosk Dec 13 '19

correct~ there was no year zero.

decade 1 = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 (10 yrs)

best decade: 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000

this decade: πŸ˜€πŸ˜€πŸ˜€πŸ˜€, πŸ˜ƒπŸ˜ƒπŸ˜ƒπŸ˜ƒ, πŸ˜„πŸ˜„πŸ˜„πŸ˜„ 😁😁😁😁 🀣🀣🀣🀣, 😨😨😨😨, 😬😬😬😬, 😟😟😟😟, πŸ₯΅πŸ₯΅πŸ₯΅πŸ₯΅<---- you are here 🀒🀒🀒🀒

Excellent post, great deductive reasoning, clear, concise verbage; you really laid it all out in a way most people could easily understand. Gonna completely forget about this in a minute tho

Year Zero is an amazing NIN album and Trent Reznor deserves more goddamn recognition.

This is the beginning...

This is all well and good, but you are not actually correct.

A decade is simply a measure of 10 years. It can start from any time. 10 years measure starting from June 19th 1876 is just as much a decade as any other span of 10 years. If you were to say "the 20th century" that would be the 20th century AD, so a measure of 100 years starting from January 1, 1901 and ending on December 31, 2000. If you were to say "the 1900s" that would be a century starting on January 1, 1900, and ending on December 31, 1999. These are two distinct things, different from each other, but both equally centuries. With decades, we do not talk about the 200th decade, no on says that, they say "the 1990s", which would be a decade starting on January 1, 1990, and ending on December 31, 1999.

So there being no year 0 doesn't actually change anything, since we don't measure decades the same way we do centuries.

u/LittleLui Dec 13 '19

So every full moon is the "last full moon of the decade", right?

u/Rcmacc Dec 13 '19

Technically yeah. Regarding the decade that started the day after the full moon 10 years prior

u/FreeLook93 Dec 13 '19

I guess you could say each full moon is the last of a decade if you want to come across like a pedantic ass hat, but "the decade" would refer to what most people consider the decade, which would be the 2010s.

u/LittleLui Dec 13 '19

if you want to come across like a pedantic ass hat

TBH I usually try to avoid that but sometimes my personality - uh - finds a way.

I try to be a nice guy, but some times my mouth doesn't cooperate.

u/Roar_Im_A_Nice_Bear Dec 13 '19

Yep. I had this conversation with my dad last week and we decided to check online. Here's the consensus we found on multiple sites:

  • the third millenium began in 2001, not 2000 (because there's no year zero, so the 1st millennium began in year 1)

  • same with centuries, the 21st century began in 2001

  • not the case with decades: decades were adopted later on, and begin in years ending in 0. So in a few days it will be a new decade.

Tl,dr: millenium goes from 1 to 1001, century goes from 1 to 101, decade goes from 0 to 10

Best post so far :)

u/MattieShoes Dec 13 '19

A century is simply a measure of 100 years.

7

u/SirMildredPierce Dec 13 '19

Yes, but *the* century is a specific 100 years.

-1

u/FreeLook93 Dec 13 '19

Yep, where did I say that it wasn't?

1

u/[deleted] Dec 13 '19

since we don't measure decades the same way we do centuries.

We do. "The Nineties", "The Eighties" and so on are specific decades. As are "The 2010s".
There is a difference between "a decade" and "the decade".

u/ericwn Dec 13 '19

Yeah, he didn't say "last full moon of an arbitrary decade that can start at any time"

0

u/FreeLook93 Dec 13 '19

Right. The point I was getting at is that we don't measure "the decade" the same way we measure "the century". While both are just a measure of 10/100 years, the meaning of "the" preceding the word has a different starting point.

β€œYear zero” isn’t really a thing. You could count the decade from 90-99 just as much as you can count it your way. Personally I think starting a decade from the whole number that represents it makes a lot more sense as far as how we refer to decades. The 20s start with 2020. The 90s started with 1990. Doesn’t that make a lot more sense?

u/[deleted] Dec 13 '19

I mean, I don't think our current calendar started anywhere near year 1, so that's all assuming a decade measures from the very beginning.

For example, we're nowhere near the 21st century. That was 4 billion years ago.

And if they don't, they can start wherever we want them to.

u/otterom Dec 13 '19

Decades, much like indices, start at 0.

u/Civil_Defense Dec 13 '19

All that matters is that we can start saying that we are in the 20's and that's the only part anyone gives a shit about.

u/MVBanter Dec 19 '19

Well lets think about this, 1 AD January 1st cant be the first day of AD, you know why, if so, that means that we decided to skip an entire year. Picture your first days, you are not 1 from the start, you are 0 and it takes a year to reach that. There ya go.

Yeah! We all know that time didn't start until 1970-01-01 00:00:00.
