Converting String to Date throws parse exception

I am trying to convert String to Date to compare from current Date and it throws parse Exception

SimpleDateFormat  format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.US);  
        try {  
            java.util.Date cookiedate = format.parse("Tue Apr 29 11:40:55 GMT+04:00 2014");  

            Calendar currentDate = Calendar.getInstance();

            String dateNow = format.format(currentDate.getTime());
              java.util.Date currDate =  format.parse(dateNow);

            if (currDate.getTime() > cookiedate.getTime()) {
                return true;
            }


        } catch (ParseException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        }

At first, you should parse the string date to Date object using EEE MMM dd HH:mm:ss Z yyyy format then convert that Date to yyyy-MM-dd HH:mm:ss format as follows...

    SimpleDateFormat  format = new SimpleDateFormat("EEE MMM dd HH:mm:ss Z yyyy");  

    try {  
        Date cookiedate = format.parse("Tue Apr 29 11:40:55 GMT+04:00 2014");  

        Calendar currentDate = Calendar.getInstance();

        format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.US);

        cookiedate = format.parse(format.parse(cookiedate));

        String dateNow = format.format(currentDate.getTime());
        Date currDate =  format.parse(dateNow);

        if (currDate.getTime() > cookiedate.getTime()) {
            return true;
        }


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

I think it is pretty obvious that formatted date "Tue Apr 29 11:40:55 GMT+04:00 2014" does not match format "yyyy-MM-dd HH:mm:ss".

If you are using format "yyyy-MM-dd HH:mm:ss" you should parse strings like 2014-03-30 10"59:23.

If you want to parse string like "Tue Apr 29 11:40:55 GMT+04:00 2014" you should use format like EEE MMM dd HH:mm:ss z yyyy. (I am not sure about z, probably it should be Z).

In your format, "yyyy-MM-dd HH:mm:ss" will match date string like "2013-03-30 15:57:00", so you get a ParseException.

If you want to parse "Tue Apr 29 11:40:55 GMT+04:00 2014", you should use "EEE MMM dd HH:mm:ss z yyyy" Change your code to

SimpleDateFormat  format = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy", Locale.US);
