 Gregorian calendar
      n : 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: New Style calendar]
