First, let’s start with…

What is a century?

A century is 100 years. In English and many other languages, centuries are ordinarily numbered. The term century is derived from the Latin centum, which means “one hundred.” Century is sometimes abbreviated to c. [1] Formalized paraphrase

A centennial or centenary is a commemoration of a hundredth anniversary, usually of an incident that occurred a hundred years ago.

How long is a Century?

A century is made up of 100 years. Although a century can refer to any time of 100 years, it is commonly described as beginning with a year ending in one and ending with a year ending in 00 or 100. The twentieth century, for example, started in 1901 and finished in 2000.

The twenty-first century started in 2001 and will conclude in 2100. This time measurement is based on the Gregorian calendar, also known as the New Style Calendar, and is used by the majority of the world today.

While a century may refer to any arbitrary period of 100 years, there are two major theories about the existence of standard centuries. The first is founded on strict construction, while the second is founded on public belief.

According to the strict construction, the first century AD began with AD 1 and finished with AD 100, with the second century covering the years 101 to 200, and so on. In this model, the n-th century begins with the year that ends with “01” and ends with the year that ends with “00”; for example, the years 1901 to 2000 constitute the 20th century in strict usage.

In traditional belief and practice, centuries are organized by grouping years that share the ‘hundreds’ digit (s). In this paradigm, the ‘n’ -th century begins with the year that ends in “00” and ends with the year that ends in “99”; for example, in popular culture, the years 1900 to 1999 comprise the 20th century.

(This is analogous to the grouping of “0-to-9 decades” that share the ‘tens’ digit.) Since both the astronomical year numbering scheme and the ISO 8601 system have a year zero, the first century starts with the year zero rather than the year one.

The century system is based on the Gregorian calendar, which is also the world’s most commonly used civil calendar.

The Gregorian Calendar 

The Gregorian Calendar is the most widely used in the world.

The Gregorian calendar, which was declared official by Pope Gregory XIII in 1582, is the basis for the majority of today’s time measurements. It replaced the Julian calendar, which was discovered to be slightly unreliable. It was first used by Italy, Poland, Portugal, and Spain.

Many Protestant countries were unable to use it because they believed it was a Catholic plot to silence their beliefs. It was introduced in 1752 by England and the colonies that went on to form the United States. It is also the most common calendar.
