- Most people probably have never accessed records that used another calendar such as Hebrew, French Revolution, Quaker, Chinese etc…
- As for the Julian and Gregorian Calendars-- like me, most people probably knew abt it BUT really didn’t give it much thought UNLESS they ran across a dual dated record-which I have not YET!!!
Once a long time ago, when I was 1st starting out, I did look at some Quaker records and probably did NOT understand their dating system–so just copied the info as written but that was the only time I’ve ever accessed Quaker records…
According to the Wiki, you can use almost any date format you want-- if RM recognizes the format such as 7th da 3rd mo 1782 ( Quaker) , it will automatically fill in the sort date of March 7, 1782-- if however you use a birth date it does NOT recognize such as 4 Nissan, 5513 (Hebrew)-- the date will turn a pale yellow and you MUST supply the sort date 8 April 1753 --otherwise there is no sort date saved but the birth date is listed in the fact-- there are good calculators online…
As for Familysearch and Ancestry-- it is best to just call them and ask as I tried Googling it and can’t find an answer—
for anybody interested here is a nice chart from
