This script demonstrates how to retrieve a Holiday Set and get a list of the holiday dates that it defines

void Main()
{
    //if the adTempus server is on a different computer, replace "." with the name
    using (var session = Scheduler.Connect(".", LoginAuthenticationType.Windows, "", ""))
    {
        using (var context = session.NewDataContext())
        {
      //retrieve the Holiday Set
            var holidays=context.GetHolidaySet("Standard U.S. Holidays");
            if(holidays==null)
                return;
            
            var startDate=new DateTime(2021,1,1);
            var endDate=startDate.AddYears(1);
            
            var matchingDates=holidays.GetMatchingDates(startDate, endDate);
            foreach(var item in matchingDates)
            {
                Console.WriteLine($"{item.MatchingDate} ({item.RuleName})");
            }
        }
    }
}
