No, Tomorrow Is Not The Start Of A New Decade

written by John Chow on December 31, 2009

Profit from binary options

If you’re thinking tomorrow is the start of a new decade, you are one year too early. The next decade doesn’t start until January 1, 2011. It seems when it comes to the calendar, many people can’t count. I remember when everyone thought Y2K was the start of the new millennium. Those are the same people who think the new decade starts tomorrow.

There Was No Year Zero

Simple logic and the ability to count will tell you when a new decade or millennium begins and end. A decade is ten years. Since there was no year zero, ten years is year 1 to 10 and a new decade starts at year 11. In other words, the last decade was 2001 to 2010. We are heading into the end of the decade, not the start of new one.

I guess this mistake isn’t as a bad as the Y2K mistake when everyone though January 1, 2000 was the start of the 21st century and the new millennium. Way more people were talking about that as year 2000 approached. It’s a good thing I only have to deal with that once every 1000 years. However, enough people are calling 2010 the start of a new decade to irritate me enough to write this post.

I feel better now. Happy New Year! :P

Even though its not the start of the new decade, it should be a good year regardless. Happy new year to everyone.

Now matter how we play with words, I hope that it must be the new dawn, without economic recession and war.

Happy new year if it is..

It might be sooner with whats on the new these days =/

So does this mean the world is going to end on December 21, 2013 instead of 2012?

Haha wishful thinking for some I guess.

It is the start of a new year, though, right? Happy New Year if it is.

Too many people kept thinking that it was the change of a decade.

Nice rant Mr Chow, but you supply no frame of reference, so you are plain wrong.

The common understanding and usage of decades has no relation to the beginning of the Gregorian calendar. The 80s was the period from 1st Jan 1980 to the 31st Dec 1989. The year 1990 is not in the Eighties.

Likewise, the 1810s encompass 1810 to 1819. 1820 is the start of the eighteen twenties.

No one (apart from pedantically inclined who can't look anything up) thinks that decades run xx01 to xx10.

Now, the 201st decade in relation to the start of the Gregorian calender DOES run 2011 to 2020, but again no one uses that term to mean 'decade'. We talk about the decade of "The Sixties" as running 1960 to 1969, 1970 is not in the sixties!

Regarding the whole Gregorian calender thing in any case, it is non-logical and has been superseded by ISO 8601 and the Astronomical year numbering system, both of which DO have year zero, and are therefore more logical, workable, AND tally with everyday understanding. Win - win.

ISO 8601 For the win. Cracking comment.

Can;t beleive that just a short while ago we were talking about y2k and the end of the world. The end has been delayed till 2012.

This is so true, everyone thinks that I am just crazy, but apparently they just cant count. Good post John.

Thank God I'm not the only one completely bugged by this!

Thank You!

I wish I was as clever as John Chow, he can do maths and stuff.

Don't need to be clever to do math, just get a calculator.

What's all this commotion about? It's 2010 and that's all we really need to know :)

Have a good one everyone!

Happy new year John!

Regardless of what year it is, it's nice to know that being a d*ck about technicalities is timeless. :)

I've got to honestly say that I did not this - I thought today was the start of the new decade.

However, we had a blue moon last night and won't get another until 2028. That's a long time to wait. Happy new year.

How do you know there was no year zero, were you there? Maybe they had the forsight to know this argument was going to come up and they actually did start in year zero.

That's why we have history books, or in our generation, PDFs and Google search. :)

Have a look at http://en.wikipedia.org/wiki/Calendar_era#Christia...

There is no year 0 in the Christian calendar.

This is so funny John. Me and my brother talked about this exact thing yesterday. Hilarious and yet true. Very good point because this is all you hear people talk about incorrectly. Also, have a happy new year John. To good times and success. Best wishes!

Going from '9' to '10' seems to be a good point to change decades IMO, when the 'bit shifts' rather than between 10 and 11.

I learnt this in primary school at history classes.

It's unbelievable how many people don't know this.

well this post has brought about the most entertaining comments of any post i can remember reading here.

whatever year it is or isn't i just hope it's a good one. In fact instead of hoping, i have decided that i will make it a good year.

here's to making 2010 a great year.

(apparently at 4:39 a.m. my time, my comments get a little cheesier than usual)

time for bed . . .shouldn't have had so many redbulls tonight

I am hoping it is a new decade, this one has not been one with a lot of ups to it. Mostly just downs and I am looking for an new start. Watching the clock with high hopes!!

More important than whether or not it's a new decade is the way we are going to say "2010" - It's "Twenty-ten" not "Two-thousand and ten" http://www.twentynot2000.com/

So the Roaring Twenties didn't include 1920? Or is it wrong to call that a decade?

I get what you are saying but sometimes you just have to go with the flow. :-)

And we all know that the '80's didn't end until 1999. One is a unit of measurement. The other is a description.

The 80's didn't end till 1999? Don't you mean 1991?

The start of the decade is arbitrary, and I choose to start it now. Yes, I understand that there was no Year Zero. However, it's not like Year One was the beginning of time. There were obviously many years before that. Do you know what the first year was *really*? If not, then *any* year is equally likely to be the beginning or ending of a decade. It certainly doesn't seem intelligent to me to get so worked up over something so arbitrary.

Nice rant John. Never thought I'd see the day where you'd be complaining about if it's a new decade or not :P

Happy New Year!

It's so true, I think many people miss. However, Happy New Year!

The idea that this is the year 2009 is not so clear cut. People didn't start even thin k about what "year" it was until the 1600's and it was pretty much a guess at how much time at passed since historical events. There is an interesting book called "The Lost Millennium" by Florin Diacu that puts forth a pretty strong argument that we may be off by as much as 1000 years, and it might be closer to the year 1000 than then year 2000. So complaining that we are off by a year doesn't make much sense - we might be off by as much as 1000 years, and there is no way to accurately pin down dates from history. So if someone wants to call this a new decade, let them. Its just an arbitrary number.

Actually, it's not really 2010 or 2009, our date is just an arbitrary number it's more like 13-14,000,000,000 somewhere in that range for the year, http://en.wikipedia.org/wiki/Age_of_the_Universe

The only reason we say 2010 is because we decided to start our calendar when Jesus was born. But reality is that if you measure humans then it's been at least 200,000 years. But if your talking about modern civilization then in "Sumer" aka modern Iraq then the true date is more like 5010.

Enjoy!

Actually every day is the start of a new decade. Jus t count 10 years from today's date and you've got your 10 years.

Big deal, how does it matter antywas?

Lol, I have to agree with you. Who cares? Happy New Year anyway though!

Certainly its not a start of a decade but yes this will be end to a decade as well.

People who think that this is start of a decade, they are bit more pessimistic with less knowledge of math :)

It's still a 10 year period from 2000 to the start of 2010.

John;

I don't mean to nit-pick but I think you might be wrong about this. I'm no theologian but I think there actually was a year zero - even though they might not have known it at the time. Year zero was simply the year before year one... right? There's got to be some historians who could better answer this but I'm not sure your premise is correct (it might be, I don't know) that there was no year zero.

Actually, Ashley, the Christian calendar begins with the year 1 (crazy, isn't it?).

According to Wikipedia, the Indian calendar is the only one which starts at 0.

I think this is hillarious but so very true

Yup net you can share it to others while making your today

Yup, there is no tomorrow without your today. But today is always there for you to make a move. dont stop keep moving.

I know that the next decade beginns officaly 2011, but for my personal use the next decade beginns tomorrow. You argument about a definition. John is mathamatically right, but a lot of people (including me) use their own definition.

So a definition is a definition and it is not right or wrong. I can't see that the difference between these two kinds of definitions of a decade has any serious effect on something.

Anyway: Happy New Year to everyone!
