   Cent.]
   1. A hundred; as, a century of sonnets; an aggregate of a

   Note: Century, in the reckoning of time, although often used
         in a general way of any series of hundred consecutive
         years (as, a century of temperance work), usually
         signifies a division of the Christian era, consisting
         of a period of one hundred years ending with the
         hundredth year from which it is named; as, the first
         century (a. d. 1-100 inclusive); the seventh
         century (a.d. 601-700); the eighteenth century
         (a.d. 1701-1800). With words or phrases connecting
         it with some other system of chronology it is used of
         similar division of those eras; as, the first century
         of Rome (A.U.C. 1-100).
         [1913 Webster]
