I have DatePicker Dialog, When I select date at that time I want to calculate age it\'s working but when I select date of current year at that time it showing the -1 age instead
public static String calculateAge(String strDate) {
int years = 0;
int months = 0;
int days = 0;
try {
long timeInMillis = Long.parseLong(strDate);
Date birthDate = new Date(timeInMillis);
//create calendar object for birth day
Calendar birthDay = Calendar.getInstance();
birthDay.setTimeInMillis(birthDate.getTime());
//create calendar object for current day
long currentTime = System.currentTimeMillis();
Calendar now = Calendar.getInstance();
now.setTimeInMillis(currentTime);
//Get difference between years
years = now.get(Calendar.YEAR) - birthDay.get(Calendar.YEAR);
int currMonth = now.get(Calendar.MONTH) + 1;
int birthMonth = birthDay.get(Calendar.MONTH) + 1;
//Get difference between months
months = currMonth - birthMonth;
//if month difference is in negative then reduce years by one and calculate the number of months.
if (months < 0) {
years--;
months = 12 - birthMonth + currMonth;
if (now.get(Calendar.DATE) < birthDay.get(Calendar.DATE))
months--;
} else if (months == 0 && now.get(Calendar.DATE) < birthDay.get(Calendar.DATE)) {
years--;
months = 11;
}
//Calculate the days
if (now.get(Calendar.DATE) > birthDay.get(Calendar.DATE))
days = now.get(Calendar.DATE) - birthDay.get(Calendar.DATE);
else if (now.get(Calendar.DATE) < birthDay.get(Calendar.DATE)) {
int today = now.get(Calendar.DAY_OF_MONTH);
now.add(Calendar.MONTH, -1);
days = now.getActualMaximum(Calendar.DAY_OF_MONTH) - birthDay.get(Calendar.DAY_OF_MONTH) + today;
} else {
days = 0;
if (months == 12) {
years++;
months = 0;
}
}
//adarsh
if (currMonth > birthMonth) {
if (birthDay.get(Calendar.DATE) > now.get(Calendar.DATE)) {
months = months - 1;
}
}//---------------------------------
} catch (Exception e) {
e.printStackTrace();
}
//Create new Age object
return years + " Y " + months + " M " + days + " days";
}
