How Many Years Are in a Decade?
A decade is a term that describes a certain time period. In the United States, a decade is defined as ten years. Decades are also used to classify historical events and age groups. The easiest way to find out how many years are in a century is to divide a year by 100. For example, year one is considered the first century, and year 101 is the second century.
10 years
Decades are periods of time of about 10 years. For example, the decade of the 20th century was made up of ten years, which means that a century is equivalent to about ten decades. Alternatively, a decade is one tenth of a millennium.
1 millennium
The term “millennium” is a time period, ranging from years x001 to y002, or 1 to 1010. The first millennium began on January 1, 1800, and ended on December 31, 2000. There are two kinds of millenniums, one for the twentieth century and one for the third.
1 millennium = 1,000 years
A millennium is a period of time that can be measured in years. It is usually expressed as a thousand-year period, but the term can be applied to periods of time that last millions of years. In the case of astronomy, the word millennium may refer to a millennium that began in the year 0 or in the year 1.
