dhxCalendarA internationalization

How can I change names of monthes and days for dhxCalendarA cell type?

You need to use the following solution:
myGrid.attachEvent(“onDhxCalendarCreated”, function(myCal){
myCal.loadUserLanguage( “your_language” );
})
Here you can find the tutorial about the internalization of the dhtmlxCalendar itself:
