no. The last year of a decade always ends in zero. The first decade started at year 1 and was 10 years long (year 1-10). Every decade to follow starts with a year ending with 1 and ends with a year ending in 0. The first day of this decade was January 1, 2001 and the last day will be December 31, 2010.
2010
Yes, he won actor of the decade last year/beggining of this year [2009/2010]
The year 2009 was in the 2000s.
This question was asked in 2009, a decade after 1999.
The "decade" of the 2000's includes the period from January 1, 2000 until December 31, 2009. If referring to the "first decade of the new Millennium", you could refer to the years 2001-2010. Because there was no "year zero" on the Gregorian calendar, each new millennium of 1000 years includes the final 1000th year (1000, 2000, etc.). However, a decade is not restricted by this convention.
No, it was a decade long event.
1900
Given that there was no year 0, the first decade would have been from year 1 to year 10 (inclusive). Adding ten-year intervals would lead to the result that the last year of the decade was 2000 and not 1999. However, that is the view of a purist mathematician - something of a minority view.
If we are to use the precedent set in the previous century (and I do) then the first decade of a century is called the oughts. The year 2009 can also be called twenty ought nine. Slightly archaic, but we don't have any good replacement.
1980 was the first year of the 1980s. It was the last year of the 8th decade of the 20th century, which ran from 1971 to 1980.
the last year it erupted was 2009
If you were born in the year 1982, you were born in the 80s decade. Decades are usually labeled simply by the second to last digit of the year. For example, the 1910s, 20s, 30s, and so on.
