Will the 22nd century start in 2100 or 2101?

The 22nd century should be counted from the year 2100.

If according to the strict mathematical calculation method, it should be calculated from 2101, but because of the backwardness of ancient science and technology, there was no concept of 0 AD at that time, not from 0 AD, but from 1 AD, the ancients missed a year when they were in the year, and when people understood this truth, it has been calculated like this for thousands of years, if it is changed, it will be very troublesome, for the sake of convenience, people have to be wrong, although the 22nd century should actually be counted from 2101, However, according to the dating custom passed down from generation to generation, people still use the year 2100 as the beginning of the calculation of the 22nd century.

False In fact, the 21st century is counted from 01 The 22nd century is counted from 2101 The AD chronology is based on the year of Jesus' birth as the first year (i.e., 1 AD), 100 years as the first century AD, 100 years as the last year of the 1st century, and 101 years as the first year of the 2nd century! Furthermore, the numbers in the chronology are ordinal words rather than cardinal numbers, so they should be read as 2008, not 2008.

It should be counted from 2101.

The year 2000 was the last year of the 20th century, and 2001 was the beginning of the 21st century.

Year 2101.

The year of Jesus' birth was 1 C.E.

So add 1 more

The 21st century starts from 2000.

The 22nd century starts at 2100.

Century Age Algorithm

A century represents a hundred years, and this odd chronology is the method.

Coming from the post-Jesus era, 1 year usually means "year of our Lord", so the first century runs from 1 to 100 C.E., and the 21st century from 2001-2100 C.E.

Chronology, on the other hand, divides a century into successive tens, which is usually applied to the Common Era. Every century from the "......Zero "to" ......Therefore, 2020 is the second decade of the 21st century, that is, the 20s of the 21st century.

The year 2023 is the twenties of the twenty-first century.

2023 is the year of the 21st century, the century, refers to the unit of calculating the era, and a hundred years is a century. When used to count days such as repentance, the century usually begins with an epoch that is divisible by 100 or a year thereafter, such as 2000 or 2001.

Each century is 100 years, so 1 100 years is the 1st century AD, and the 2nd century AD is from 101 to 200, so the 20th century is 1901 to 2000, and 2001 is the beginning of the 21st century and ends in 2100.

The age depends on how many tens of digits it is, and that's it. For example, in 1898, the ten digits were 9, so it was the nineties. 1355, the ten is 5, that is, the fifties, and the ages of each century are grouped by ten years.

It's the 20s of the 21st century, because 21 is 20, and 2021 is the 20s.

21 The 30s should belong to the 30s.

2001 What year is 2010?

2011 What year is 2020?
