-                    DateToDay Method
-                    ----------------
-    The DateToDay method takes a date in string format and returns
-    the name of a day. The approach behind this method is very
-    simple, we first take a string date and check whether their date
-    is valid or not, if the date is valid then we pass this date
-    to the predefined date method and get the date of the day We do
-    it and find the name of the day, after that give the name of
-    the day to the user, if the date is wrong, then tell the user
-    that the given date is not valid.
