Razor

<DxDateRangePicker @bind-StartDate="@DateTimeStart"
                   @bind-EndDate="@DateTimeEnd">
    <DayCellTemplate>
        <a class="@GetCssClassNames(context)">@context.Day.ToString()</a>
    </DayCellTemplate>
</DxDateRangePicker>

@code {
    DateTime DateTimeStart { get; set; } = DateTime.Today;
    DateTime DateTimeEnd { get; set; } = DateTime.Today.AddDays(7);
    CalendarData Data { get; set; } = new CalendarData();
    string GetCssClassNames(DateTime date) {
        if(Data.PersonalDays.Exists(d => DaysEqual(d, date)))
            return "fw-bold text-success";
        if(Data.Holidays.Exists(d => DaysEqual(d, date)))
            return "text-danger";
        if(Data.BirthDates.Exists(d => DaysEqual(d, date)))
            return "fw-bold text-info";
        return string.Empty;
    }
    bool DaysEqual(DateTime date1, DateTime date2) {
        return (date1.Year == date2.Year && date1.DayOfYear == date2.DayOfYear);
    }
}
