Need Help to figure out date behavior

Here is my code

String currentdate = new String();

Calendar calender = Calendar.getInstance();

currentdate = calender.get(Calendar.YEAR) + "-" +

calender.get (Calendar.MONTH) + "-" +

calender.get(Calendar.DAY_OF_MONTH) ;

My question is I have tested this code on 3 different windows machines,but for some reason

it gives me june as in month where as its july.

I know that day light saving does impact one hour but whats this?( month time saver?..:-).....)

please help...
