<h2>Definition and Usage</h2>
<p>The setMonth() method is used to set the month.</p>
<h2>Syntax</h2>
<table class="ex" cellspacing="0" border="1" width="100%">
<tr>
<td>
<pre>dateObject.setMonth(month,day)</pre>
</td>
</tr>
</table>
<br />
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr>
<th align="left" valign="top" width="20%">Parameter</th>
<th align="left" valign="top" width="80%">Description</th>
</tr>
<tr>
<td valign="top">month</td>
<td valign="top">Required. A numeric value between 0 and 11 representing the
month</td>
</tr>
<tr>
<td valign="top">day</td>
<td valign="top">Optional. A numeric value between 1 and 31 representing the
day</td>
</tr>
</table>
<br />
<hr />
<h2>Tips and Notes</h2>
<p><b>Note:</b> The value set by setMonth() is a number between 0 and 11.
January is 0, February is 1 and so on.</p>
<p><b>Note:</b> This method is always used in conjunction with a Date object.</p>
<hr />
<h2>Example 1</h2>
<p>In this example we set the month to 0 (January) with
the setMonth() method:</p>
<table class="ex" cellspacing="0" border="1" width="100%">
<tr>
<td>
<pre><script type="text/javascript"></pre>
<pre>var d=new Date();
d.setMonth(0);
document.write(d);</pre>
<pre></script></pre>
</td>
</tr>
</table>
<p>
The output of the code above will be:</p>
<table class="ex" cellspacing="0" border="1" width="100%">
<tr>
<td>
<pre><script type="text/javascript">
var d=new Date()
d.setMonth(0)
document.write(d)
</script></pre>
</td>
</tr>
</table>
<br />
<hr />
<h2>Example 2</h2>
<p>In this example we set the month to 0 (January) and the day to 20 with
the setMonth() method:</p>
<table class="ex" cellspacing="0" border="1" width="100%" id="table1">
<tr>
<td>
<pre><script type="text/javascript"></pre>
<pre>var d=new Date();
d.setMonth(0,20);
document.write(d);</pre>
<pre></script></pre>
</td>
</tr>
</table>
<p>
The output of the code above will be:</p>
<table class="ex" cellspacing="0" border="1" width="100%" id="table2">
<tr>
<td>
<pre><script type="text/javascript">
var d=new Date()
d.setMonth(0,20)
document.write(d)
</script></pre>
</td>
</tr>
</table>
