AL The reason one might want a date calculator is to convert dates from the Julian to the Gregorian calendar systems, and vice versa? When England changed dating systems, as an example, a person who was born/died in Old Time,does not have the same current date as their present new anniversary. Also, Parish Records dating did not follow the calendar year, at one time, the opening of a new year being set as Lady Day, not January 1st. This means that it can appear that marriage dates and the date of birth of issue seem to suggest that the bride was (considerably) pregnant, at the time of the vows.My recall is that the C of E did not modernize until very early in 1804, when the new system of registrations took place, and was after that made standard. There are a number of sites with calculators (some of which can be downloaded) and a good engine one use is www.google.com to locate one and to read about the issues involved. PS: Many people do not realize that some of the popular Family software databases - including Generations and Family Tree Maker, might automatically convert dates from OT to NT without the user being aware of this sly manipulation! Both programs have a preference tool, so that one can turn the converter off or on - if one started out with one or the other, changing the preferences does not alter the already entered records. I'll bet that maybe only one person in 50 realizes that the UK dating system changed, in modern times in the mid 1700's - and that there were a number of previous changes too, to bring the calendars in step with real, solar time! -----Original Message----- From: b1caez01 [mailto:b1caez01@home.com] Sent: Sunday, June 11, 2000 11:55 AM To: BORDER-L@rootsweb.com Subject: Date Calculator A while ago, I requested help in finding a calculator which would assist in establishing a birth date, when you know the death date and the information from a tomb stone. The following url is just the ticket...although I have not tried it yet. I am going to file it until I can recall why I needed it...old age, you know!
