Parsing ISO 8601 date format like 2015-06-27T13:16:37.363Z in Java

I am trying to parse a


This is my current code:

public String getCreatedDateTime() {
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-ddEHH:mm:ss.zzzz");
try {
Date date = simpleDateFormat.parse("2015-06-27T13:16:37.363Z");
return date.toString();
} catch (ParseException e) {
return "Error parsing date";

As you can see, I just put a constant in the parse() method for testing purposes.

So, this is what I am trying to parse:


This is the
pattern that I am using:


I keep getting the ParseException.

I know that it is proably because of the .zzzz at the end but I have no idea what .363Z might stand for so I just used some random letters. Bad idea.

I'll appreciate your help a lot. Thank you!

Try with this pattern (note the X at the end and the 'T' in the middle):


From Java's SimpleDateFormat's documentation:

ISO 8601 Time zone:


For parsing, "Z" is parsed as the UTC time zone designator.

And, from the part where it describes the different characters:

X - Time zone - ISO 8601 time zone


If using Android, then "X" is not supported.

You can use this pattern (note Z is a literal now):


But then you'll get the date on your current timezone and would need to convert it to UTC if needed.
