Dear List: Today, I found a FREE calendar calculator web site which provides conversions and calendars which are technically correct. I needed to find out a calendar date for births when a baptismal date was given, and the birthdate was say "a Saturday earlier." The application works fine, but takes some time getting used to. :-) One thing I learned was that not all early baptisms in England were on a Saturday following a birth (a somewhat popular notion.) the URL for the site is: http://www.calendarhome.com/tyc/
