Java Date format weird

I have an issue where I would like to get the start of the day, however it seems to be setting it to 12:00 via automatic.

SimpleDateFormat dfFull = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
String todayDate = dfFull.parse("2014-06-06 00:00:00");

today = dfFull.format(todayDate);
System.out.println(today);

Why is this spitting out:

2014-06-06 12:00:00

The 12:00:00 is the issue

You should use HH for hours in this case.

SimpleDateFormat dfFull = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String todayDate = dfFull.parse("2014-06-06 00:00:00");

today = dfFull.format(todayDate);
System.out.println(today);

Now you will get the out put as

2014-06-06 00:00:00

And again if you use hh that mean you are using 12 hour format while HH means 24 hour format

That is because hh represents the hour in 12 hour format. You need to use HH instead.

SimpleDateFormat dfFull = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

Have a look at the docs for more info.

Also, on a side note, there is a typo in your code.

SimpleDateFormat dfFull = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date todayDate = dfFull.parse("2014-06-06 00:00:00"); // todayDate must be of type Date and not String
String today = dfFull.format(todayDate); // today should be of type String
System.out.println(today);
