For those doing research in the province of Zeeland, it is important to understand the French Republican Calendar, as civil registration started earlier in the province of Zeeland than it did in the other provinces. When reading documents from 1796 until about 1 January 1806, the researcher is going to encounter strange names for months, a different start of the year, and a different beginning of each month.
The French Republican Calendar had 12 months of 30 days each. At the end of the year there were 5 extra days used for vacation and festival. The first day of this calendar was 22 September 1792, but the calendar was not established by law until 5 October 1793. The official end, by law, was 1 January 1806, but the unoffical end was 11 September 1805.
