Help creating date/calander

[morano773]

I'm trying to implement a Date class to create a simple application for " Major U.S. holidays calendar System ", that provides a list of major holidays for a given year AND prints the calendar for the given year either online or write to a file.

I need help finishin up the class date.h, which is

#ifndef DATE_H
#define DATE_H
#include <string>
#include <iostream>
using namespace std;

string Month[]={"" , "January", "Febraury", "March", "April", "May", "June", "July",
	"August", "September", "October", "November", "December"};

int daysInMonth[2][13] = { { 0,31,28,31,30,31,30,31,31,30,31,30,31} ,
							{ 0,31,29,31,30,31,30,31,31,30,31,30,31} };
string DOW[] = { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturady"};
class Date{

private:
	int *month ;
	int *day ;
	int *year ;

public:

	// constructors

	Date(int month, int day, int year) ;
	Date()  ;     // default constructor

	Date(Date &other) ;  // copy constructor
	Date(string mmddyyyy) ;  // constructor that takes a string as parameter e.g "10/31/2012"

	~Date() ;

	// overlaod assignment operator 

	Date & operator=(Date & rhs) ;
	Date & operator++() ;
	Date & operator++(int) ;
	Date & operator--() ;
	Date & operator--(int) ;
	bool operator ==(Date & rhs) ;
	bool operator != (Date & rhs) ;
	bool operator > (Date & rhs) ;
	bool operator < (Date & rhs) ;

	int operator-(Date & rhs) ;     
	Date & operator+(int ) ;
	


	// accessors

	int getDay() ;
	int getMonth() ;
	int getYear() ;

	bool valid(int m, int d, int y);   // validate the triple is indeed a valid date
	string toAscii(int n) ;		//  string representation of the integer
	
	static Date toDate(int doy, int yr) ;  // 

	void display() ;   // display date in the format of   mm/day/year e.g. 10/31/2012
		

	string toString() ; // returns the string format of dayOfWeek Month Day, Year  e.g. Wednesday October 31, 2012



	// returns true if the given year is a leap year and false otherwise

	static int isLeap(int year) {

	     return (( year % 400 == 0  ) || ( year % 4 == 0  && year % 100 != 0 )) ;
   }

	// returns the day code the the new year day of the given year

	static int get_day_code( int year ) {
                return ( year + ( year - 1 ) / 4 - ( year - 1 ) / 100
                             + ( year - 1 ) / 400 ) % 7;
   }
	// overloading get_day_code that returns the day code of the specific day
	
	static int get_day_code(int year, int month , int day);

	
	

	int dayOfWeek();		// return the day code of this day ;
	


	int dayOfYear() ; 		// returns the day of the year, eg,  the day of year for Feb 28 is 59.




};

Then, i need help implementing the code for each holiday. using this code

#include <iostream>
#include <string>
#include <iomanip>
#include "Date.h"
#include <fstream>

using namespace std;

void app1() ;
void app2() ;
void print_calendar( int year );
char *major[]={"New Year Day","MLK Birthday","Valentine's Day","President Day","St.Patrick's Day","April Fools","May Day","Mother's Day",
	"Memorial Day","Father's Day","Independence Day","Labor Day",
	"Columbus Day","Halloween","Election Day", "Veterans Day","Thanksgiving Day", "Christmas"};
char * dayofweek[] = {"Sunday", "Monday", "Tuesday","Wednesday", "Thursday", "Friday", "Saturday"};

void print_calendar( int year, ostream &out );


void menu() {
	cout << "\n\t\tType 1 for major holidays ";
	cout << "\n\t\tType 2 for Calendar  ";
	cout <<"\n\t\tType 3 to quit.";
	cout << "\n\n\t\tPlease enter your choice :";;
		
}
int main() {
	
	int choice ;
	cout << endl << endl << "\tWelcome to CSC262  Holidays/  Calendar System: \n\n";
	while (true) {
		menu() ;
		cin >> choice ;

		switch(choice) {
		case 1:  app1() ; break ;
		case 2 : app2() ; break ;
		case 3: break ;
		default:  cout << "\n\n\t\tInvalid choice \n"; break;
		} 
		if ( choice == 3 ) break ;

	}

	cout << "\n\n\tThank you for using U.S. Major Holidays Calendar System! \n";
	cout << "\n\n\t\tBye! \n\n";
	return 0 ;
}

I've commented where I need help.

I'm have no clue what to do to finish this, and it's taken me a while to get what i've got. any help is appreciated
