error C2664

I have this code that I am trying to compile and I keep getting an error C2664 message. I am not sure what to do with the code that it is pointing to. (This is just part of the program code but I get this same error in another part of the code)

Code:

#include <iostream>

using std::cout;
using std::endl;

#include <ctime>

#include <cstdlib>

enum Months { JAN = 1, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC };

void generateDate( int &, int &, int );
void printDate( Months, int, int );
int validDate( int, int );

int main()
{
    int month = 1;
    int day = 1;
    int year = 1900;
	int getYear;
	int getMonth;
	int getDay;
	int Month;
	int myMonth;

    srand( time( 0 ) );

    printDate( month, day, year );
    year = getYear ( year );
    month = getMonth( month );
    day = getDay( day );

    if (validDate (month, day, year) == true )
        printDate ( month, day, year );

    return 0;

}   // end main

This is the whole error message:
error C2664: 'printDate' : cannot convert parameter 1 from 'int' to 'enum Months'
Conversion to enumeration type requires an explicit cast (static_cast, C-style cast or function-style cast)

Any help will be appreciated.

Change

Code:

int month = 1;

to

Code:

Months month = JAN;
