Hello, I feel so ignorant sometimes and forgive me for this. I am beginning to look for marriages, deaths etc. which happened in the early 1800’s. One of which for example is a marriage in Habsheim for March 18, 1809. In looking for this I noticed and have forgotten the “formula” or the Calendar for this era. i.e L’an XII, and other possible words to signify a date, Florial?? or something like that. Can someone please give a rough lesson on these dates, what to look for, and when the calendar changed to a more formal one. Does this make sense? When looking for a specific date such as March 18, 1809, I have no clue what I’m looking at, or for. Thank you for helping a novice here. Scott
