#include<stdio.h>int isrunnian(int year){if((year%4==0&&year%100!=0)||year%400==0)return 1;else return 0;}int dijitian(int year,int month,int day){int i,result=day;for(i=1;i<month;i++){if(i==1||i==3||i==5||i==7||i==8||i==10||i==12)result+=31;else if(i==4||i==6||i==9||i==11)result+=30;else if(i==2){if(isrunnian(year))result+=29;else result+=28;}}return result;}int main(){int year,month,day;int i,n,j,cnt;scanf("%d",&n);for(i=0;i<n;i++){scanf("%d-%d-%d",&year,&month,&day);cnt=dijitian(year,month,day);if(isrunnian(year))cnt=366-cnt;else cnt=365-cnt;for(j=year+1;j<year+18;j++){if(isrunnian(j))cnt+=366;else cnt+=365;}cnt+=dijitian(year+18,month,day);if(month==2&&day==29)printf("-1\n");else printf("%d\n",cnt);}return 0;}
