East Asian age reckoning originated in China and continues in limited use there along with Tibet and Japan, but is still common in Korea. People are born at the age of one, i.e. the first year of lifetime using an ordinal number (instead of "zero" using a cardinal number), and on Chinese New Year or New Year's Day one year is added to their age.[1][2] Since age is incremented at the beginning of the lunar or solar year, rather than on the anniversary of a birthday, people may be one or two years older in Asian reckoning than in the international age system.

Start of decade = 12am 01.01.2020

11 years are more than a decade...

There are 3 types of people in the world.

Those who can count & those who can't.

Yes from a math stand point,and religious ect ways with some,maybe it's 1 year behind,but some of us go the way of when things start and end,ie 2000-2010,a decade,2010-2020,a decade.

Not real good with math and would have to double check,but seems from start till now,it's been 202 decades.

The problem is that 2000-2010 is 11 years !! 2010-2020 is also 11 years !!

The end of the 202nd decade isn't until the end of this year (2020). This means that 2021 is the first year of the next decade.

[Rob S]

From the start,counting from day one (AD or AC,whichever it is) to end of 2019,seems to be 202 decades.

I am a little confused, what has this got to do with this debate in Australia?

[BENT_8]

From a mathematic standpoint then those who consider this the last year of the 2nd decade of this century, then yes, its correct, but we don't count decades by mathematical reasoning, it is simply the decade of whatever the first number is and so the noughties started on 1/1/2000, the 10's on 1/1/2010 and the 20's on 1/1/2020.
Whilst it would make mathematical sense to consider 2030 a year of the 20's, it would sound ridiculous.

[CJR09]

I think some one old enough should break out their abacus, work it out then let us all know

That is referring to two different things though, which is where the confusion is.

2020 is part of the current decade. It's also the start of the '20's, however that is two different things.

Depends what your definition of current decade is, like I said, from a mathematical standpoint it is part of the decade which starts on 1/1/2011, which is one interpretation, others who don't care for the math consider the 1/1/2020 the start of the next decade because 20 is a number in the 20's.

You wouldn't consider a 20yr old a teenager, they would be in their twenties, same thing.

That's my interpretation of it, having said that, its not something I've really considered in depth because it really doesn't matter to anything in everyday life.
For me, the most interesting moment in time was at 12:34:56 on 7/8/90, something which only occurs once every 100 years.

Oh, the pain . . . .

[GO FURTHER]

Okay... Let's compare what is considered as the "turn of a century".

The 21st century in accordance with the Gregorian calendar, began on January 1, 2001, and will end on December 31, 2100.

Therefore 2020 is the last year of the decade.
The new decade therefore starts on 1st Jan 2021.

Problem solved.

[Rob S]

That's maths,only numbers,in reality end of decade is over.Anyway the whole thing is numbers anyway,since a certain point in history.

Apparently there were people and things happening before that.

Whichever way someone wants to look at it,but because of these differences in numbers it can affect our lives in modern times,with all these different calculations.

My wife teaches at an English language school for newly arrived children (In Australia!). How old parents believe their children are vary depending on what country they came from.

The answer is, it depends on which country they come from. I hope that clears the confusion.

You're a year short. If you count 1 AD as year number 1, then 202 decades end at the end of 2020.

It only ends at the end of 2019 if you include 1 BC in your count. Why would you do that ?

2030 is not a year of the 20s even mathematically. The 20s goes from 2020 to 2029 but that is not a normal decade, it is part of one decade plus part of another.

2030 is the last year of the 3rd decade of the 21st century. The 3rd decade of this century goes from 2021 to 2030.

[roddy1960]

Depending on who you talk to and depending on variable between the Julian and Georgian calendar and which religion you follow ........ etc .

here's a bit of a discussion on what day of the week by modern standards January 1st of the year 0001 would have been

https://www.quora.com/What-was-the-d...st-Jan-0001-AD

Seems to have either been a Saturday or a Monday . In recognition of the fact it might have been a Saturday do ya reckon they would have given all the peasants and stuff a public holiday Monday off in lieu !!!!!!!!!!!!

If a horse in born on 01 August 2019, is it currently aged 0 or 1. ?

2030 is the last year of the 3rd decade of the 21st century. The 3rd decade of this century goes from 2021 to 2030.

Dr Terry.

You've just contradicted yourself, in the first sentence you say 2030 isn't part of the 20's, then go on to say the 3rd decade is 2021 to 2030.

If 2025 is a year of the twenties and that decade consists of the year 2021 as you've said, plus the following 9 years, then 2030 is part of the 20's from a mathematical point, which I agree with and said above, however, the majority of people consider the 20's as any year starting with the 2, so 2020 to 2029 and the 30's any year starting with the 3, so 2030 to 2039.

Dr Terry

Wouldn't the 365 days of 1 (AD or AC)count as the first year in reality,so like I said,mathematically I guess according to numbers it would be end of decade at end of 2020,but in reality wouldn't it be end of decade at end of 2019.

Like in reality wouldn't end of 9 (AD or AC) and turns to number 10,it's already been 10 years,and in the 11th.

simple, 0 or zero, it won't turn one until 01/08/20. It will turn 10 on 01/08/2029

It's not a contradiction.

When referring to an era i.e. 20's, 30's etc, you aren't referring to the time in context of the current timeline. That is where the confusion is. In context of the continuous counting up of years, the 'next decade' doesn't start until 2021.

So yes, 2030 isn't part of the 20's, but it is part of the 3rd decade of this century.

[prydey]

When all said and done it doesn't really matter.

I just threw it out there as a bit of fun as it messes with my ocd

I think you've answered your own question & no, I haven't contradicted myself.

The 20s are 2020 to 2029, but this is not a decade as such, it is just 10 years starting at 2020.

I don't believe that you can say that 2030 is part of the 20s, when in fact it is the last year of the 3rd decade. This is what I was trying to illustrate.

See, this is the issue. You have to start somewhere like your age for example. You are born on day 1, you are 1 year of age after 12 months & 10 years old after full 10 years. So you are 10 years old during your 11th year, not during your 10th.

During your 19th year, just before your 20th birthday, you are not 20, you're still 19. You are 20 years at the time of your 20th birthday & also into your 21st year. But again you are not 21 until one year later, at your 21st birthday.

What these other guys are saying is that the 20th decade of this century is completed at the beginning of the 20th year, but just like your birthday you are not 20 until the end of the 20th year.

Dr Terry

[roKWiz]

Its a bit like when we lived in the 20th century it was 19** by numbered year.

Ok, I think we're actually on the same page here.
I agree that technically this is the final year of the 2nd decade of this century, if we were to count from Christs birth, this is the final year of the 202nd decade, 2020 is also considered the first year of the 20s which is where the confusion comes in, history considers the decade of the 20s etc. to begin on 1/1/20 and finish on 31/12/29 which is why people have celebrated the new decades beginning.

So if someone is born on the last day of the year when they are 2 days old they are also 2 years old?
Then when they are 366 days old they are 3?
