Wrong date conversion

Question

I have a problem in date conversion in my android application. I have date strings like 2017-11-11 11:52 which its date is equal to 2017-Nov-11 but it is parsed as 2017-01-11 in below code snippet:

DateFormat df = new SimpleDateFormat("yyyy-MM-DD HH:mm");
try {
    Date date = df.parse("2017-11-11 11:52");
    Log.v("DATE_TAG","Date Time:"+date.toString());

} catch (ParseException e) {
    e.printStackTrace();
}

The log output of above code is "Wed Jan 11 11:52:00 GMT+03:30 2017".

Is there anything wrong in my date format string?

The above SimpleDateFormat format makes no sense to me. Why do you want to format `"2017-11-11 11:52"` as `"yyyy-MM-DD HH:mm"`, if it's already in that format? — Phantômaxx, Dec 11 '17 at 09:18
Refer to [SimpleDateFormat](https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html) — ADM, Dec 11 '17 at 09:22

You are using a wrong dateformat. DD stands for the day of the year, not the day of the month. You have to use dd instead. You can check the SimpleDateFormat documentation, where it is stated that DD can range from 1 to 365.

So your code should look like this:

DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm");
try {
  Date date = df.parse("2017-11-11 11:52");
  Log.v("DATE_TAG","Date Time:"+date.toString());
} catch (ParseException e) {
  e.printStackTrace();
}

Good question, @W3hri. This one is the best explained of the three correct answers. – Ole V.V. Dec 11 '17 at 09:22
The one from Gowtham was downvoted too, a bit suspicious ... – W3hri Dec 11 '17 at 09:23
But neither is anymore. Someone changed their mind in time. – Ole V.V. Dec 11 '17 at 09:24
You're right. Strange – W3hri Dec 11 '17 at 09:24

D is day in year e.g 189. Use d instead

Clearly noted from your output : Read Document

D is Day in year (1-365)
d is day in month (1-31)

Change this

DateFormat df = new SimpleDateFormat("yyyy-MM-DD HH:mm");

to

DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm");

D is used for (Day in year), so in you case you need to use d (is day in month ). please use this Format "yyyy-MM-dd HH:mm"
