#include<bits/stdc++.h>
using namespace std;

    int a,b;
    cin>>a>>b;
    for(int i=1;i<=b;i++){
        a*=a;
        a%=7;
    }
    if(a==1)
        cout<<"Monday";
    if(a==2)
        cout<<"Tuesday";
    if(a==3)
        cout<<"Wednesday";
    if(a==4)

    if(a==6)
        cout<<"Saturday";
    if(a==0)
