Hi,
Thank you to use Ancestris.
This software is designed to follow the GEDCOM standard.
This standard define only four calendars (Gregorian, Julian, French Republican, Hebrew).
The dates are parsed to separate Day, Month and Year accordingly to one of theses calendars.
You can put the date you wan, but the date won't be recognized and won't be parsed.
This means that in several windows, the date won't be displayed.
We not plan to put a specific calendar.
For the font, if there is an option in the parameter tab of the report, you can change the font.
If not, let me know the one you want to use, I will try to set an option for you.
