You can customize the first day of the adoption of the Gregorian calendar by defining the macro greg_cutover, e.g. -Dgreg_cutover=2020,10,15 (format: YYYY,MM,DD). The default is the fourteenth of September of 1752.
The default first day of the week can also be configured at compile time with the macro greg_first_weekday, where 0 is Sunday and 6 is Saturday. E.g. -Dgreg_first_weekday=1 for Monday.
