Hello ,
In timeGridWeek the header is correctly but in dayGridMonth the list starte with the wrong days.
There's a mismatch on the header I tried to do this but it had no effect:
firstDay:'1',
locale:'fr',

timeGridWeek view:

dayGridMonth view :

is there a solution for this ?

Hello,

The firstDay option accepts number, not string. So try firstDay: 1.
