The way we describe ages, including years or people’s ages, can sometimes seem strange if you consider that years beginning “20” are referred to as “21st Century” (and similarly, years starting “19” were the “20th Century”). There is a very logical reason for this, though: when it comes to age, and time that has passed, we assign numbers after a period of time is complete.
Where is the 21 in 20xx?
Any year beginning “20xx” is part of the 21st Century because they form the 21st set of hundred years in recorded time. When we reach 2100, time will have been recorded for 21 centuries. Consider the start of recorded time – the first century were the first hundred years of time, years through 0 to 99. At 100 years, the first century was completed, and the second century began (100 to 199 years).
This is the pattern we stick to – we refer to a period of time as the first, second, twentieth or other period while it is being completed. But a number denoting age is assigned after that period has been completed. So 2016, for example, comes within the time that the 21st hundred years are being completed (making it the 21st Century), but we will not give years the number 21xx until after those 2099 years are complete.
How years work for ages
The same principle is used when we talk about how old someone or something is. As with the first century, a child is in its first year until it turns 1, but we do not say it is 1 until after that year is complete. If you are 15 years old, for example, then you have completed 15 years of life. At the same time, after you turn 15 you are actually entering your 16th year.
Typically, this is how age is described – we describe an age within the period it is completing, but we label the age with a number that shows completed time.
Note that this is not something that gets generalised to all labels of time. When are talking about age, it is true, but when describing something like a course or schedule you will find the time period being completed as a name. So during college you can say you are Year 1, Year 2 or Year 3, for example, meaning that is the year you are currently completing. But when it comes to talking about centuries, and giving numbers for ages, keep in mind that the label we use to describe an ongoing period of time is different to the number we assign it!

We are definitely a weird species

Not 2100 – 2200
The “1” when counting , for example in 101 above, is really important
There was no year 0 and the first century ended at the end of the year 100 AD. As 2000 approached, everyone got excited about the change in digits from 19 to 20 and decided to hold their parties on 31 December 1999. And why not? If it’s good enough for Prince, it’s good enough for the rest of us. But the new millennium began on 1 January 2001. This kind of confusion has been in the air since there has been a perceptible body of public received ideas and opinion – since there has been a public in the modern sense. We see evidence of it as the eighteenth and nineteenth centuries approached. But confusion and a partyish disposition don’t change the anno domini system used for our calendar.
A total confusion, all the calculation above are wrongfully analyse. When there are no year call 0, the 0 year didn’t started in this generation. The beginning of numbers are follows…0,1,2,3,4,5,6,7,8,9,10,
11,12,13,14,15,16,17,18,19,20,21,22.
The 0 number years was after BC & A.D.
From 1,2,3…19,20,21. etc are the conventional year and century counting.
Remember, the 0 years was 1 to 999 years was A.D. After Death.
So the 0 to 999years was not counted. But instead it was call B.C & A.D
From 1 onward, the century begin
1 called 1st century =100years,
2 called 2nd century = 200years,
3 called 3rd century =300years,
4 called 4th century = 400years, etc till
10 called 10th century = 1000years
11 called 11th century = 1100years, etc till 18 called 18th century = 1800years
19 called 19th century = 1900years
20 called 20th century = 2000years
that is 1900 to 1999, the 19th century completed. The century is the 19th And not 99.
2000 to 2099, the 20th century completed.
Remember….
12th year, 12th century, that is, 1200 to 1299. The century is the 12th.
13th, 14th…till 19th which should be 19 century and written as 1900 to 1999. The century is the 19 and not 99.
20th century which is 20xx or 2000 to 2099. The century is the 20th.
21st which should be 21 century, 2100 to 2199. Counting from 00 to 99 makes 100… The century.
So my conclusion is that, the said century to be recognized or used is wrong. The year 2022 we’re presently falls in 20th century and so it is not 21st century.
Take more examples,
19 hundred = 1900 = 19thCent
20 hundred = 2000. = 20thCent
21 hundred = 2100. = 21stCent. Etc
The hundred is the years in within 0- 99=100
And the owner of each Cent is the 19,20,21,22…etc.
If any mistake, questions or explanation.
