Howdy folks - been some time since I posed a query or two, but the following questions seem to be on my mind most recent. And I would like all answers to reflect the practice here in America, and not necessarily what may have been practiced in England and Europe or elsewhere: 1. What is the time period of the O.S. (old dating system) and when did the current one we use, begin? Umm, were there more than one 'old system'? 2. Regarding 'leap' years, how was that aspect handled in the old system? 3. I've seen many instances where someone was born, or had some other event identified using the old system, but passed away or had some other event documented which used the new or current system of dating - is there some method to determine the accuracy of the time or dating difference? 4. Is there some method or practice commonly in existence which attempts to convert old system dates to the new system? I'd tend to think not, for there has to be a formula of some sort in place to help determine the difference? See question #3. I've many reasons for asking these questions. And yes, I can go online to produce the answers pretty well. But I did want all the members - at least those of us who don't know - to be better informed on the subject. I would be especially interested in hearing from any members who've had to work through the formulas to produce their family connections, and how they faired through it all. I will assume it is not simple, but I'd like to try to learn it anyway. I do hope you all are enjoying your summer, and time away from the pressures of life in general. God Bless all who are in pain!
