Day slots are generated with regard to culture-specific day of the week ordering. For example, if the first day of the month is a Tuesday, then the corresponding day slot will be third in the list, with two empty slots preceding it, for the USA culture, because Sunday is the first day of the week in the USA; however, it will be second in the list for the Russian culture, because Monday is the first day of the week in Russia. A represented culture is controlled by the C1Calendar CalendarBase.CalendarHelper property.

To specify a place in the calendar control UI tree (defined in the C1Calendar.Template) where the abovementioned panel with days will be placed, the C1CalendarPresenter type instance should be used.
