Check date with todays date

I have written some code to check two dates, a start date and an end date. If the end date is before the start date, it will give a prompt that says the end date is before start date.

I also want to add a check for if the start date is before today (today as in the day of which the user uses the application) How would I do this? ( Date checker code below, also all this is written for android if that has any bearing)

if (startYear > endYear) {
    fill = fill + 1;
    message = message + "End Date is Before Start Date" + "\n";
} else if (startMonth > endMonth && startYear >= endYear) {
    fill = fill + 1;
    message = message + "End Date is Before Start Date" + "\n";
} else if (startDay > endDay && startMonth >= endMonth && startYear >= endYear) {
    fill = fill + 1;
    message = message + "End Date is Before Start Date" + "\n";
}

Using pure Java: 

public static boolean isToday(Date date){
        Calendar today = Calendar.getInstance();
        Calendar specifiedDate  = Calendar.getInstance();
        specifiedDate.setTime(date);

        return today.get(Calendar.DAY_OF_MONTH) == specifiedDate.get(Calendar.DAY_OF_MONTH)
                &&  today.get(Calendar.MONTH) == specifiedDate.get(Calendar.MONTH)
                &&  today.get(Calendar.YEAR) == specifiedDate.get(Calendar.YEAR);
    }

public static boolean itIsToday(long date){
    boolean result = false;
    try{
        Calendar calendarData = Calendar.getInstance();
        calendarData.setTimeInMillis(date);
        calendarData.set(Calendar.HOUR_OF_DAY, 0);
        calendarData.set(Calendar.MINUTE, 0);
        calendarData.set(Calendar.SECOND, 0);
        calendarData.set(Calendar.MILLISECOND, 0);

        Calendar calendarToday = Calendar.getInstance();
        calendarToday.setTimeInMillis(System.currentTimeMillis());
        calendarToday.set(Calendar.HOUR_OF_DAY, 0);
        calendarToday.set(Calendar.MINUTE, 0);
        calendarToday.set(Calendar.SECOND, 0);
        calendarToday.set(Calendar.MILLISECOND, 0);

        if(calendarToday.getTimeInMillis() == calendarData.getTimeInMillis()) {
            result = true;
        }
    }catch (Exception exception){
        Log.e(TAG, exception);
    }
    return result;
