Method

booleanisSameDay(Calendar cal1, Calendar cal2)
Determines if two calendar objects represent the same day. 
if (cal1 == null || cal2 == null)
    return false;
if (cal1.get(Calendar.YEAR) != cal2.get(Calendar.YEAR))
    return false;
if (cal1.get(Calendar.MONTH) != cal2.get(Calendar.MONTH))
    return false;
if (cal1.get(Calendar.DAY_OF_MONTH) != cal2.get(Calendar.DAY_OF_MONTH))
    return false;
...
booleanisSameDay(Calendar cal1, Calendar cal2)
Check to see if two Calendars are on the same Day, by comparing the year, month and date 
int year1 = cal1.get(Calendar.YEAR);
int year2 = cal2.get(Calendar.YEAR);
if (year1 == year2) {
    int month1 = cal1.get(Calendar.MONTH);
    int month2 = cal2.get(Calendar.MONTH);
    if (month1 == month2) {
        int day1 = cal1.get(Calendar.DAY_OF_MONTH);
        int day2 = cal2.get(Calendar.DAY_OF_MONTH);
...
booleanisSameDay(Calendar cal1, Calendar cal2)
is Same Day 
return cal1.get(Calendar.YEAR) == cal2.get(Calendar.YEAR)
        && cal1.get(Calendar.MONTH) == cal2.get(Calendar.MONTH)
        && cal1.get(Calendar.DAY_OF_MONTH) == cal2.get(Calendar.DAY_OF_MONTH);
booleanisSameDay(Calendar cal1, Calendar cal2)
Returns whether the two specified times are on the same day 
if (cal1.get(Calendar.DAY_OF_YEAR) != cal2.get(Calendar.DAY_OF_YEAR)) {
    return false;
if (cal1.get(Calendar.YEAR) != cal2.get(Calendar.YEAR)) {
    return false;
return true;
booleanisSameDay(Calendar cal1, Calendar cal2)

Checks if two calendars represent the same day ignoring time. 

if (cal1 == null || cal2 == null) {
    throw new IllegalArgumentException("The dates must not be null");
return (cal1.get(Calendar.ERA) == cal2.get(Calendar.ERA)
