Pope Gregory issued a papal bull in 1582 ordering that the new calendar be introduced. It was adopted immediately by Catholic countries and principalities, but the Greek church and the Protestant countries refused. The changeover straggled over several centuries - Romania used the Julian calendar until 1919. In September 1752, England and the American colonies adopted the Gregorian calendar. "Cal 9 1752" correctly handles the transition as adopted by England and the United States. -- Terry Gaetz -- gaetz@uwovax.uwo.ca or gaetz@uwovax.BITNET
