/*
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.
