Hi,
<add key="site1culture" value="ar-AE" />
<add key="site1uiculture" value="en-US" />
first one controls number formats, calendars, date formats, etc
second one controls which resx files are used but not sure about months and day names since that goes with the calendar.
In the next release of Event Calendar Pro I will add extra css classes in month view for the day names so there will be classes like
.day-Monday {}
.day-Tuesday {}
so that you could control the style for any day of the week and override the .mpcalendarweekendday {} if it selects the wrong days
This way you could keep everything as English including date formats but still make friday and saturday styles as you want
I'll post again on this thread after the next release of Event Calendar Pro
Best,
Joe
