The UR Calendar pane automatically uses your Windows locale setting for the first day of the week. This is driven by the registry value:
HKEY_CURRENT_USER\Control Panel\International\iFirstDayOfWeek
A value of 6 indicates Sunday; a value of 0 indicates Monday. If you set that registry value to the desired day and restart UR, the UR calendar should honor it.
