To Ira and french users, Cft-Win 3 includes UCC 1.2. The french republicain calendar used is modified form from UCC 1.0. Using this calendar, three republican years are wrong : - 01 vend 04 giving 22/09/1795 instead 23/09/1795 - 01 vend 08 giving 22/09/1799 instead 23/09/1799 - 01 vend 12 giving 23/09/1803 instead 24/09/1803 Original form in UCC 1.0 gived right conversion for years 01-15.
