Although any period of 10 years is a decade, a convenient and frequently referenced interval is based on the tens digit of a calendar year, as in using "1960s" to represent the decade from 1960 to 1969. Often, for brevity, only the tens part is mentioned (60s or sixties), although this may leave it uncertain which century is meant. These references are frequently used to encapsulate popular culture or other widespread phenomena that dominated such a decade, as in The Great Depression of the 1930s.
Since the common calendar starts with year 1, its first full decade is the years 1 to 10, the second decade from 11 to 20, and so on. So while the "2000s" comprises the years 2000 to 2009, the "201st decade" spans 2001 to 2010.
A decade may also refer to an arbitrary span of 10 years. For example, the statement "during his last decade, Mozart explored chromatic harmony to a degree rare at the time," merely refers to the last 10 years of Mozart's life without regard to which calendar years are encompassed.
Thus, an unqualified reference to, for example, "the decade" or "this decade" may have multiple interpretations depending on the context.
For decades of the 20th century, the term 'decade' often conjures not just a set of ten years but a distinct era roughly approximating those ten years - for example, the 'sixties' often refer to events that took place between c. 1963 and 1971 and conjure memories of the counterculture, flower power and other things going on at the time.

Famous quotes containing the word distinctions:
“Television ... helps blur the distinction between framed and unframed reality. Whereas going to the movies necessarily entails leaving ones ordinary surroundings, soap operas are in fact spatially inseparable from the rest of ones life. In homes where television is on most of the time, they are also temporally integrated into ones real life and, unlike the experience of going out in the evening to see a show, may not even interrupt its regular flow.”
—Eviatar Zerubavel, U.S. sociologist, educator. The Fine Line: Making Distinctions in Everyday Life, ch. 5, University of Chicago Press (1991)
“It is commonplace that a problem stated is well on its way to solution, for statement of the nature of a problem signifies that the underlying quality is being transformed into determinate distinctions of terms and relations or has become an object of articulate thought.”
—John Dewey (18591952)
“Distinctions drawn by the mind are not necessarily equivalent to distinctions in reality.”
—Thomas Aquinas (c. 12251274)
