    copied!<p>This code isn't good.</p> <p>I don't understand why you're doing all this parsing of Strings to get to Date and visa versa when you have java.text.DateFormat and java.text.SimpleDateFormat to do it easily for you.</p> <p>I think this is better. See if you agree:</p> <pre><code>package com.contacts.util; import java.text.DateFormat; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.ArrayList; import java.util.Calendar; import java.util.Date; import java.util.List; public class DateUtils { private static final DateFormat DEFAULT_FORMAT = new SimpleDateFormat("dd-MMM-yyyy"); public static void main(String[] args) { try { Date startDate = ((args.length &gt; 0) ? DEFAULT_FORMAT.parse(args[0]) : new Date()); Date endDate = ((args.length &gt; 1) ? DEFAULT_FORMAT.parse(args[1]) : new Date()); List&lt;Date&gt; weekdays = DateUtils.getWeekdays(startDate, endDate); Calendar calendar = Calendar.getInstance(); for (Date d : weekdays) { calendar.setTime(d); int dayOfMonth = calendar.get(Calendar.DAY_OF_MONTH); int month = calendar.get(Calendar.MONTH); int year = calendar.get(Calendar.YEAR); // System.out.println(DEFAULT_FORMAT.format(d)); System.out.println("day: " + dayOfMonth + " month: " + (month+1) + " year: " + year); } } catch (ParseException e) { e.printStackTrace(); } } public static List&lt;Date&gt; getWeekdays(Date startDate, Date endDate) { List&lt;Date&gt; weekdays = new ArrayList&lt;Date&gt;(); if ((startDate == null) || (endDate == null)) return weekdays; if (startDate.equals(endDate)) { if (isWeekday(startDate)) { weekdays.add(startDate); } } else if (startDate.after(endDate)) { weekdays = getWeekdays(endDate, startDate); } else { Calendar calendar = Calendar.getInstance(); calendar.setTime(startDate); Date d = startDate; while (endDate.equals(d) || endDate.after(d)) { if (isWeekday(d)) { weekdays.add(d); } calendar.add(Calendar.DATE, 1); d = calendar.getTime(); } } return weekdays; } public static boolean isWeekday(Date d) { if (d == null) return false; Calendar calendar = Calendar.getInstance(); calendar.setTime(d); int dayOfWeek = calendar.get(Calendar.DAY_OF_WEEK); return ((dayOfWeek &gt;= Calendar.MONDAY) &amp;&amp; (dayOfWeek &lt;= Calendar.FRIDAY)); } } </code></pre>
