<a name="id1072427"></a><h2>Description</h2>
<p>The elements of a date_generator "phrase" are parsed from the input stream in a particular order. All elements are required and the order in which they appear cannot change, however, the elements themselves can be changed. The default elements and their order are as follows:</p>
<div class="itemizedlist"><ul type="disc">
<li><p>partial_date => "dd Month"</p></li>
<li><p>nth_day_of_the_week_in_month => "nth weekday of month"</p></li>
<li><p>first_day_of_the_week_in_month => "first weekday of month"</p></li>
<li><p>last_day_of_the_week_in_month => "last weekday of month"</p></li>
<li><p>first_day_of_the_week_after => "weekday after"</p></li>
<li><p>first_day_of_the_week_before => "weekday before"</p></li>
</ul></div>
<p>Weekday and Month names and formats are handled via the date_input_facet.</p>
<p>TODO: add doc-comments for which elements can be changed </p>
