#include<bits/stdc++.h>
#define int long long
#define itn int
#define FOR(i,l,r) for(int i=(l);i<=(r);++i)
using namespace std;
int fx[110]={31,29,31,30,31,30,31,31,30,31,30,31};
signed main()
{
    int ans=0;
    int a,b;
    cin>>a>>b;
    FOR(i,1,12)
        FOR(j,1,fx[i])
        {
            int c=(j%10)*1000+(j/10)*100+(i%10)*10+(i/10);
            itn s=c*10000+i*100+j;
            if(s<a||s>b) continue;
            ans++;
        }
    cout<<ans;
    return 0;
}
