I was able to get the current day using:

string datenow = DateTime.Today.ToString("dddd / M / yyyy");
string[] words= datenow.Split(' ');
string day = words[0];

This is how i am reading the RSS feed:

 public class RssReader
    {
        public static List<RssNews> Read(string url)
        {
            var webClient = new WebClient();

            string result = webClient.DownloadString(url);

            XDocument document = XDocument.Parse(result);

            return (from descendant in document.Descendants("item")
                    select new RssNews()
                    {
                        Description = descendant.Element("description").Value,
                        Title = descendant.Element("title").Value,
                        PublicationDate = descendant.Element("pubDate").Value
                    }).ToList();
        }
    }

As per your Requirement you just want to get description of current day .You have list of News feeds with Title ,description ..etc Now You can change your class (add a method in Your class ) if day is Current Day

public static string GetCurrentDayDescription(){

   var lst = Read("url");
   var resDescription = (from x in lst where x.Title.Contains(day) 
                          select x.Description).ToArray() ;
    return resDescription[0] ;
}
