I have tried to use both utility functions but have had no luck.

Its the line 65 of the code you pasted the function toNumber is called with 0 arguments and you have only one definition of the function that takes 1 string argument.
Either provide another function (a type of default one) that takes no argument; or declare the only parameter as default parameter; or pass some string value in function call at line 65...

think about the purpose of getDay function.
what is supposed to be returned? a number? a string? think about that and you will realize the right code for that function. remeber what toNumber and toName are for. and remember what is the type of the variable day.

hope this will do, if not, ask again an ill try to be more clear about what i meant.
