I guess April 18 1693 is in the Gregorian Calendar? If located in Italy it will be. Not every country switched fro the Julian calandar to the Gregorian Calendar on October 5 1582, e.g Great Britain did it on September 3 1752 and Switzerland did it partly in 1584 and partly in 1701. These dates can be found in 'Explanatory Supplement to the Ephemeris' published by HMSO in London, pages 414-416.
