<h3>TYPE</h3>
Function

<h3>DESCRIPTION</h3>
<p>

</p>

<h3>SYNOPSIS</h3>
<p>
<blockquote><pre>easter_day(dt DATETIME)
  RETURNS DATE</pre></blockquote>
</p>
<p>
  Input:
  <ul>
    <li><strong>dt</strong>: a DATETIME object, by which computation is made. 
	    <strong>dt</strong> is only checked for its <strong>YEAR</strong> part. All other information (month, day, time) is irrelevant.
		Hence, the two inputs <strong>'2012-01-01'</strong> and <strong>'2012-08-27 15:16:17'</strong> yield with the same result.
	</li>
  </ul>
</p>

<blockquote><pre>mysql&gt; SELECT common_schema.easter_day('2012-01-01') AS easter_day_2012;

| 2012-04-08      |
