Your pattern does not correspond to the input string at all... It is not surprising that it does not work. This would probably work better:
SimpleDateFormat sdf = new SimpleDateFormat("EE MMM dd HH:mm:ss z yyyy", Locale.ENGLISH); Then to print with your required format you need a second SimpleDateFormat:
Date parsedDate = sdf.parse(date); SimpleDateFormat print = new SimpleDateFormat("MMM d, yyyy HH:mm:ss"); System.out.println(print.format(parsedDate)

Notes:
- you should include the locale as if your locale is not English, the day name might not be recognised - [IST is ambiguous and can lead to problems][1] so you should use the proper time zone name if possible in your input.
