Sidereal years conversion
The sidereal year is the time taken for the Earth to complete one revolution of its orbit, as measured against a fixed frame of reference (such as the fixed stars, Latin sidera, singular sidus). Its average duration is 365.256363004 mean solar days (365 d 6 h 9 min 9.76 s).
Decade is a period of 10 years. 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.
