What Century Are We In Now? - When Does A Century Starts And Ends?

Updated on March 26, 2011

21st Century

We are now in 21st century which started from the beginning of the year 2001 and this century will end at the end of the year 2100. The 1st century started from the beginning of the year 0001 and ended at the end of the year 0100. This is only valid for the Gregorian calendar which is also known as the Western calendar or the Christian calendar and it’s the internationally accepted civil calendar.

Birth of Christ

Years before the birth of Christ are referred to as BC meaning “Before Christ”. Years after the birth of Christ are referred as AD meaning “Anno Domini”. AD may also means “Year of the Lord Jesus Christ” to some people.

Gregorian calendar

In the Gregorian calendar, there is no year Zero. Year Zero is just a popular imagination of man as he has become used to counting numbers from 0 to 9. Problems started when someone decided that 1 AD will follow immediately after 1 BC. This means the number of years between 1 BC and 1 AD is 1 year and not 2 years.

Birth of Jesus Defies All Mathematical Logic

It was a guy called Aloysius Lilius from Naples, Italy who was an adviser to Pope who imagined that Jesus Christ should not be portrayed to be born on year Zero. Even if it was you, would you agree to propose that Christ was born on year Zero? He had to be given something. Yes, Jesus was born in such a way that his year of birth defies all mathematical logic. He was born somewhere between 1 BC and 1 AD but not at year Zero. And a Pope by the name Gregory XIII decreed the calendar in a papal bull on 24th February 1582 and since what pope has decided can not be wrong, we all followed from there. This is why we count years starting from January 1, 1 AD.

      Wrong if the first century started on Jan 1st,001-Jan 1st-100. That would only be 99 yrs do the math. this is how each century should be. 1st century all starting on Jan 1st & ending when Jan 1st starts. the 1st century would be 0-100, 2nd 101-201, 202-302, & so on, once a year is used it can't be used again. do the math & you'll understand.the 17th century started on 1616 Jan 1st & ended on 1716 12:00.01am Jan 1st. I think it does start from 0 because when your born it takes 364 1/4 days for you to become a year old.
