Explanation / Answer

public static int daysPassed(int month, int day, int year){
int daysPassed = 0;

if(month == 1){
daysPassed = day; // for month =1, passed days of the calender from january initial will be assigned // to daysPassed
}
if(month == 2){
daysPassed = 31 + day; // for month =2, total days from january to today of the calender will be assigned // to daysPassed
}
if(month == 3){
