This is untested, but should work:

Open up calendar.php, and find a appearences of (It appears twice I think) :

PHP Code:

  $yearbits = '';
  for ($gyear = 2000; $gyear < ($NumYear + 3); $gyear++)
  { // generate select menu since 2000 and for the next 3
    $yearbits .= "\t\t<option value=\"$gyear\">$gyear</option>\n";
  } 


and replace with

PHP Code:

  $yearbits = '';
  for ($gyear = 2003; $gyear < ($NumYear + 3); $gyear++)
  { // generate select menu since 2000 and for the next 3
    $yearbits .= "\t\t<option value=\"$gyear\">$gyear</option>\n";
  } 


I think that'll work
