title: Finding Part of a Sheet Name
body: <p>I want to update a worksheet. The name of the worksheet changes with the date.</p>
  <p>As an example the worksheet would have been named</p>
  <blockquote>
  <p>&quot;Hello World 6.13&quot; on Monday<br />
  &quot;Hello World 6.17&quot; today</p>
  </blockquote>
  <p>How can I looks for the sheet name that <em>starts</em> with &quot;Hello World&quot; and <em>ignores the date code</em>?</p>
