Enumeration that includes WEEKS, MONTHS, YEARS
<p>I would like to use an enum that includes WEEKS, MONTHS, YEARS.</p>

<p>The <a href="http://docs.oracle.com/javase/8/docs/api/java/util/concurrent/TimeUnit.html" rel="nofollow"><code>java.util.concurrent.TimeUnit</code></a> enum only goes up to <a href="http://docs.oracle.com/javase/8/docs/api/java/util/concurrent/TimeUnit.html#DAYS" rel="nofollow">DAYS</a>. Is such an enum defined in the java language? </p>
