This is done by defining custom style to apply to a marked days and then adding dates to MarkedDates (absolute dates), MonthlyMarkedDates (for monthly marked dates) or AnnuallyMarkedDates collections. The style is specified by MarkedDatesStyle, MonthlyMarkedDatesStyle and AnnuallyMarkedDatesStyle properties.
