<p><strong>setDate()</strong> 메서드는 현재 설정된 월의 시작 부분을 기준으로 {{jsxref ( "Date")}} 객체의 날짜를 설정합니다.</p>

<h2 id="Syntax">Syntax</h2>

<pre class="syntaxbox"><code><var>dateObj</var>.setDate(<var>dayValue</var>)</code></pre>

<h3 id="Parameters">Parameters</h3>

<dl>
 <dt><code>dayValue</code></dt>
 <dd>월의 일을 나타내는 정수입니다.</dd>
</dl>

<h3 id="Return_value">Return value</h3>

<p>1970 년 1 월 1 일 00:00:00 UTC와 주어진 날짜 사이의 밀리 초 ({{jsxref ( "Date")}} 개체도 변경됩니다).</p>

<h2 id="Description">Description</h2>

<p>dayValue가 해당 월의 날짜 값 범위를 벗어나면 setDate ()는 그에 따라 {{jsxref ( "Date")}} 객체를 업데이트합니다. 예를 들어, dayValue에 0이 제공되면 날짜는 이전 달의 마지막 날로 설정됩니다.</p>
