the decade, also decade or Dezennium is one period of 10 years.
In its strict meaning provided with ordinal numbers, the decade is used for the historical timing, for example „the first decade of the twentieth century “. This began naturally onlyat the 1. January 1901 and ended to 31. December 1910.(See the year zero).
Besides there are the so-called „common decades “, for example „the 20's 20. Century “. These are however not completely identical with „the third decade20. Century “, since the first logical-proves, the year 1920 in and the year 1930 excludes, which include latter term, just as logically, the year 1920 out and however the year 1930 also. „The usuellen decades become usual “also only off the twenties upward used, of „decimal “years to speak is rather unusually, „Nuller “years sounds completely artificial. The science of history uses therefore primarily the actual decades.
