In general usage, centuries are built by grouping years based on their shared digits. In this model, the 'n' -th century started/will start on the year (100 x n) - 100 and ends in (100 x n) - 1. For example, the 20th century is generally regarded as from 1900 to 1999, inclusive..
Then, how centuries are counted?
We start counting from year 1 and always have. It takes a hundred years to merit the label “century”. It follows then that the first century AD in the Gregorian calendar was from 1 to 100. The 2nd from 101 to 200, and the 20th century from 1901 to 2000.
One may also ask, is 2020 the 21st century? The 2020s (pronounced "twenty-twenties" or two thousand (and) twenties), shortened to the '20s) is the current decade in the Gregorian calendar, began on 1 January 2020 and will end on 31 December 2029.
Similarly, you may ask, how are we in the 21st century?
The 21st century is the current century of the Anno Domini era or the Common Era, in accordance with the Gregorian calendar. It began on January 1, 2001, and will end on December 31, 2100. It is distinct from the century known as the 2000s, which began on January 1, 2000 and will end on December 31, 2099.
How does the century system work?
Century refers to blocks of hundred year periods starting from January 1 of year 1, and continuing up to December 31 of year 100. The second century started immediately in completion of first century and ended on December 31, 200. The twentieth century started on January 1, 1901, and ended on December 31, 2000.
