   Note: Century, in the reckoning of time, although often used

         hundredth year from which it is named; as, the first

         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
