Calc. for finding holidays that are the 'first Monday of September'. When instantiated with 'fifth' kday of month, the result will be the last kday of month which can be the fourth or fifth depending on the structure of the month.</p> +<p>The algorithm here basically guesses for the first day of the month. Then finds the first day of the correct type. That is, if the first of the month is a Tuesday and it needs Wenesday then we simply increment by a day and then we can add the length of a week until we get to the 'nth kday'. There are probably more efficient algorithms based on using a mod 7, but this one works reasonably well for basic applications. </p> +<div class="refsect2" lang="en"> +<a name="id1074632"></a><h3> +<a name="nth_kday_of_monthconstruct-copy-destruct"></a><code class="computeroutput">nth_kday_of_month</code> construct/copy/destruct</h3> +<div class="orderedlist"><ol type="1"><li><pre class="literallayout"><a name="id933193-bb"></a>nth_kday_of_month(week_num week_no, day_of_week_type dow, month_type m);</pre></li></ol></div> +</div> +<div class="refsect2" lang="en"> +<a name="id1074668"></a><h3> +<a name="id899170-bb"></a><code class="computeroutput">nth_kday_of_month</code> public member functions</h3> +<div class="orderedlist"><ol type="1"> +<li><pre class="literallayout"><span class="type">date_type</span> <a name="id899175-bb"></a>get_date(year_type y) <span class="bold"><strong>const</strong></span>;</pre></li> +<li><pre class="literallayout"><span class="type">month_type</span> <a name="id962849-bb"></a>month() <span class="bold"><strong>const</strong></span>;</pre></li> +<li><pre class="literallayout"><span class="type">week_num</span> <a name="id962861-bb"></a>nth_week() <span class="bold"><strong>const</strong></span>;</pre></li> +<li><pre class="literallayout"><span class="type">day_of_week_type</span> <a name="id800396-bb"></a>day_of_week() <span class="bold"><strong>const</strong></span>;</pre></li> +<li><pre class="literallayout"><span class="type"><span class="bold"><strong>const</strong></span> <span class="bold"><strong>char</strong></span> *</span> <a name="id1104045-bb"></a>nth_week_as_str() <span class="bold"><strong>const</strong></span>;</pre></li> +<li> +<pre class="literallayout"><span class="type"><span class="bold"><strong>virtual</strong></span> std::string</span> <a name="id1073625-bb"></a>to_string() <span class="bold"><strong>const</strong></span>;</pre> +<p>Returns a string formatted as "M4.3.0" ==> 3rd Sunday in April. </p> +</li> +</ol></div> +</div> +</div> +</div> +<table xmlns:rev="http://www.cs.rpi.edu/~gregod/boost/tools/doc/revision" width="100%"><tr> +<td align="left"></td> +<td align="right"><small>Copyright © 2001-2005 CrystalClear Software, Inc</small></td> +</tr></table> +<hr> +<div class="spirit-nav"> +<a accesskey="p" href="partial_date.html"><img src="images/prev.png" alt="Prev"></a><a accesskey="u" href="date_time/doxy.html#id1109842"><img src="images/up.png" alt="Up"></a><a accesskey="h" href="index.html"><img src="images/home.png" alt="Home"></a><a accesskey="n" href="first_kday_of_month.html"><img src="images/next.png" alt="Next"></a> +</div> +</body> +</html> |
