import java.util.Calendar;
import java.util.GregorianCalendar;
import java.util.Scanner;

public class Q1 {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
   
        System.out.println("请输入年月,格式如2009-09");
        Scanner scanner = new Scanner(System.in);
        String yearMonth = scanner.nextLine();
        String[] str = yearMonth.split("-");
        //1.得到该月第一天的日历
        Calendar c = new GregorianCalendar(Integer.parseInt(str[0]), Integer.parseInt(str[1])-1, 1) ;
        //2.得到该月第一天星期几
        int week = c.get(Calendar.DAY_OF_WEEK);
        //3.这个月有多少天
        int days = c.getActualMaximum(Calendar.DAY_OF_MONTH);
        System.out.println(week + " "+ days);
        System.out.println("日\t一\t二\t三\t四\t五\t六");
        
        int d = week-1;
        for(int i = 0 ;i < d ;i ++){
            System.out.print("\t");
            
        }
        System.out.print(1+"\t");
        d++;
        for(int i = 2; i <= days;i++){
            if(d == 7 ){
                d=0;
                System.out.println();
            }
            System.out.print(i+"\t");
            d++;
        }
    }
