Convert date to milliseconds gives me wrong date java

Question

I want to convert the following datetime do milliseconds :

17/07/2015 13:30

For this I have used the following code:

SimpleDateFormat f = new SimpleDateFormat("dd/mm/yyyy hh:mm");
Date d = null;
try {
    d = f.parse(date);
} catch (ParseException e) {
}
long milliseconds = d.getTime();

But when this date I add to the calendar in Android it seems that the date is 17 of January not 17 of July.

"mm" means minutes - so `dd/mm/yyyy hh:mm` should almost certainly be `dd/MM/yyyy HH:mm`. Note the change from `hh` to `HH` too. See http://codeblog.jonskeet.uk/2015/05/05/common-mistakes-in-datetime-formatting-and-parsing/ — Jon Skeet, Jul 17 '15 at 07:28

It should be like this :-

SimpleDateFormat f = new SimpleDateFormat("dd/MM/yyyy HH:mm"); with MM for months not mm for minutes & HH for 24-Hours instead of hh for am/pm Hours

I suspect the OP also wants HH instead of hh. – Jon Skeet Jul 17 '15 at 07:28

I found that you have typo in date format dd/mm/yyyy hh:mm it should be dd/MM/yyyy HH:mm now please have look into my code and dateformate for android

SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy HH:mm", Locale.ENGLISH);
 String input = "17/07/2015 13:30";
 Date datestr = formatter.parse(input);

 **long date = datestr.getTime();** // what you want 

// revers of your Date  

Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(datestr.getTime());
String output = formatter.format(calendar.getTime())
