TOPIC: change format date in calendar view

sorry, i posted a ticket because i could not access to the forum.
now i can , so :

i'd like to change the format of the date in each calendar views :
IE : in french format day/month instead of month/date
i changed the index.php in components/com_dtregister/views/calendar/tmpl but it does not work.
i think it is in calendar.js
but i don't know how to change it

serge

any idea ?

As of version 2.7.10, the calendar date format will show appropriately based on the format you have selected in configuration.
