OOP and operator overloading

[khatereh]

Can you please explain to how this project has to be done? I'm a little bit lost, I think I should do everything in my .h file
Write your class and member functions.
1.Implement a code that allows to access your object with extraction operator >> and insertion operator >>
2. Implement 1 day after feature by using operator overloading.
3. Find a creative way to calculate and display the integer representing a day.
4. Your client program needs to get the input for a user and demonstrate your class, display the integer representing a day, and overloaded operators designed in the step 4 and 5. See example output below. The user enters values in bold.
This program converts a month and day of month into a day of the year in the range 1..365
Enter month and day (Example: January 3): March 1
Number of days from January 1 to your selected date: 60
The next day is March 2 .

Here is what I have in my .h file so far, am I on the right track?

  
#include <string>
#include <iostream>
using namespace std;

#ifndef Date-H
#define Date_H

class Date
{
	int day;
	string month;

public:

	Date(){ day;}
	//prefix
	Date operator++(){
		++day;
		return *this;
	}
	void displayDay(){ cout << day << endl; }

	~Date();
	//Accessor Functions.
	int getDay();
	string getMonth();

private:

	//Member variables.
	int newDay;
	string newMonth;
};
#endif
