  New Style calendar
      n 1: the solar calendar now in general use, introduced by
           Gregory XIII in 1582 to correct an error in the Julian
           calendar by suppressing 10 days, making Oct 5 be called Oct
           15, and providing that only centenary years divisible by
           400 should be leap years; it was adopted by Great Britain
           and the American colonies in 1752 [syn: Gregorian calendar
           , New Style calendar]
