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}]
