December 2019 was full of nostalgic posts remembering the best films, food, TV shows, and travel destinations of the decade. Even Twitter made a list of the decade’s best tweets – but plenty of Twitter users are here to remind you 2019 wasn’t, in fact, the final year of the decade.
And why is that?
Time experts (okay, that’s not what they’re called but it sounds cool) say that Anno Domini (A.D.) didn’t have a year 0. The A.D. system is the basis of how we keep track of time in our modern era.
As the argument goes, 1 was the first year in the Anno Domini system, so the first year of each decade is the one beginning in 1.
Of course, it makes sense that people would track the decade by the changing tens place. If you study the year 1960 in history class, books will say it’s a part of the 60s. The same would obviously be true about the 20s, if we were to think about it logically.
Except that it’s just not entirely logical.
Not everyone is happy about this, and some of those people have aired their grievances on Twitter.
i just need to get something straight
2019 is not the end of the decade
the end of 2020 is the end of the decade
the start of 2021 is the start of a new decade
2019 has NOTHING to do with the end of the decade

2019 is not the end of the decade, 2020 is. The first decade went from Year 1 to Year 10, and so it progressed. There was no Year 0 – we went straight from 1 BC to 1 AD.

But Twitter has been around for 10 years now and this argument has played out on the site before.
For the record 2009 IS NOT THE END OF THE DECADE! Decades end in 10. #fb

Some people (most people) don’t really care about these technicalities because frankly, it’s easier to go with the things the public recognizes even if it’s wrong.
Lady on the radio saying it’s technically not the end of the decade until 2021.
Me, yelling at the radio:
IT’S PEOPLE LIKE YOU WHO DEMOTED PLUTO!

Others tried to find a compromise.
Yes there was no year 0. However, that's no reason to kick ourselves in our own genitalia for the rest of time. The losers who were around from year 1-9 just got a 9 year decade. NBD. From then on we all got nice, healthy, neat, 10 year decades starting with 10-19, 20-29, etc.

Yes, arguing over the end of the decade seems like a waste of time, but it also shows us that time is subjective. It’s difficult to change someone else’s perspective on humanity’s milestones.
In the meantime we’d like to know your thoughts, did you celebrate 2019 as the end of the decade or are you trying to get people to understand that the decade hasn’t technically ended? We’d love to read comments about this!
