Definition: In 1582, by papal decree, Pope Gregory XIII replaced the Julian calendar with the Gregorian calendar (named after himself). This calendar was developed to make up for the deficiencies in the Julian calendar which caused it to depart from the natural solar cycle over time. To get back in sync with the solar cycle, the Gregorian calendar dropped 10 days from the month of October in 1582, and introduced Leap Years to keep this problem from recurring. Of primary importance to genealogists, is that the Gregorian calendar was not adopted by many protestant countries until much later. Great Britain and her colonies adopted the Gregorian, or "new style" calendar in 1752. Some countries, such as China, did not adopt the calendar until the 1900's.

Pronunciation: [gruh-gor-ee-uhn kal-uhn-dur] • (noun
