difference between two dates in java in 'EST' time zone -

i have parse string date, let givendate, est timezone. also, have take current date, let currentdate in est timezone. current timezone ist (gmt+5:30).

if currentdate greater givendate need add day currentdate.

here solution have implemented.

simpledateformat df = new simpledateformat("mm/dd/yyyy"); calendar givendate = calendar.getinstance(timezone.gettimezone("est")); givendate .settime(df.parse("01/08/2016"));  calendar currentdate = calendar.getinstance(timezone.gettimezone("est")); if(currentdate.get(calendar.year) > givendate .get(calendar.year) ||             currentdate.get(calendar.day_of_year) > givendate.get(calendar.day_of_year)){         currentdate.add(calendar.date, 1); }  system.out.println("final date : "+df.format(currentdate.gettime())); 

is there better solution this?

also, following has been tickling mind.

consider code snippet

simpledateformat df = new simpledateformat("mm/dd/yyyy");    calendar givendate = calendar.getinstance(timezone.gettimezone("est")); givendate .settime(df.parse("01/07/2016")); system.out.println(givendate .get(calendar.date));         //6        system.out.println(givendate .get(calendar.day_of_month)); //6 system.out.println(givendate .get(calendar.day_of_year));  //6 

why getting 6 date, day_of_month, day_of_year? expect must return 7 given date 7 days starting of year 2016.

but if add following line after first line of above code, above mentioned fields returning 7. reason of this?

df.settimezone(timezone.gettimezone("est")); 

.

you need set timezone simpledateformat class, , can compare parsed date current time:

simpledateformat df = new simpledateformat("mm/dd/yyyy"); df.settimezone(timezone.gettimezone("est")); date givendate = df.parse("01/08/2016");  calendar currentdate = calendar.getinstance();  if(currentdate.gettime().compareto(givendate) > 0) {     currenttime.add(calendar.date, 1); } 

keep in mind date object represents current time (number of seconds since epoch) in utc timezone.
