A decade :D
A decade is ten years. A century has 100 years. Therefore, there are ten decades in a century. (100 divided by 10 = 10). A generation is considered 20 years. Silver wedding anniversary = 25 years Golden wedding anniversary = 50 years
Since 1 Decade is 10 years. 10X10=100 100 years or 1 Century
That would be the 19th Century (also known as the 1800's). 1800-1899, or 1801-1900 if you want to be technical, were the years of the XIXth Century. X is the Roman numeral for ten, and IX is nine, so XIX = 19.
Let's work this out together; by the end it will make sense. In a base ten systen (our numbering system based on the typical number of digits humans have on their hands), we begin counting at the number one, completing each set after ten. Like so: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. After each set of ten, we begin again at one; like so: 11, 12, and 21, 22, etc. After ten sets of ten we reach one hundred, repeating the previous method. We do not stop countuing one hundred at 99. Likewise we do not stop counting to one thousand at 999. Now, ten years is a decade, one hundred is a century, and one thousand is a millenium. At ten plus one day of the next year, you have a decade plus one day until 365.25 have passed and you have one decade and one year. The same is true for a century and a millenium. The first century, figuratively began at 1 AD, as did the first millenium. the second century began on 1 January 101 AD and ended 31 December 200 AD. On 1 January 201 AD, the third century AD began. Now extend this to the millenium: 1 January 1 AD to 31 December 1000 AD was the first millenium. 1 January 1001 AD to 31 December 2000 was the second millenium. The third began 1 January 2001 AD. We always begin counting with one.
Popular culture holds the year 2000 as the first year of the 21st century and the 3rd millennium, due to a tendency to group the years according to decimal values, as if year zero were counted. According to the Gregorian Calendar this distinction falls to the year 2001, because the 1st century was retroactively said to start with year AD 1. Since the calendar has no year zero, its first millennium spans from years 1 to 1000, inclusive, and its second millennium from years 1001 to 2000.*This question is locked.

Do you EVER start Zero, One, Two, etc.? No you would start with One. It is the same for Calenders, year 1 comes first not year zero. It is the same for any Century you choose to talk about.Simple math answers this question. If you divide 2000 by 100 the result is 20 with a remainder of 0. Therefore 2000 is the last year of the 20th century.
There are not a thousand years in a century. There are a hundred years in a century. A thousand years is ten centuries.
A decade/ten years.
No because a century is a 100 years and 10 years is a decade
100 years, or a century.
Ten years.
Ten Years Equals A Decade, 100 Years equals A Century.
Ten years is one decade. A century is 100 years, or 10 decades.
Because... there are ten years in a decade - therefore there are ten decades in a century ! The prefix 'dec' means ten.
One century or 100 years.
No, a decade is every ten years, a century is every 100.
A decade is ten years. A century has 100 years. Therefore, there are ten decades in a century. (100 divided by 10 = 10). A generation is considered 20 years. Silver wedding anniversary = 25 years Golden wedding anniversary = 50 years
