Century

A century is a 100-year era. centuries are counted sequentially. The term century is derived from the Latin word centum, which means "one hundred."  Century is abbreviated as “c”.

A centenary is a one-hundredth anniversary, or celebration of one’s 100 years, usually of an occurrence that occurred one hundred years ago.

Starting and End of the Century:

While a century may refer to any 100-year era, there are two schools of thought on the existence of traditional centuries. One is founded on rigid construction, while the other is founded on common understanding.

The first century AD, according to strict construction, started with 1 AD and ended with 100 AD, with the same trend going onward. The n-th century begins with the year that ends in "01" and ends with the year that ends in "00" in this model. As a result, a century can only have one year, the centennial year, which begins with the number of the century. For example, In 19 century 1900 is the last year.

Years are grouped in centuries based on their shared digits, according to traditional belief and practice. The 'n' -th century, according to this model, begins with the year ending in "00" and ends with the year ending in "99." The twentieth century, for example, will be described as the period from 1900 to 1999, inclusive. In the century of 100 years, there was also the occurrence of the leap year. The difference between a year and a leap year is only 1 day. In Leap year, there are 366 days and in a normal year, there are 365 days. And leap years always occur after every 4 years. And this difference of 1 day makes the difference in the number of days in the century. 

The 1st century is 1 year from 100 years.

The 2nd century is 101 years from 200 years ago.
