This is an example of what one may call straight coding - just plain features used.

<?php

class Dayofweek {
  # constant init values okay
  private $a = array('Mon', 'Tues', 'Wed', 'Thurs', 'Friday','Sat', 'Sun');
  function getDow($n) {
    if ($this->isInbounds($n)) {
        return $this->a[$n];
    } else {
        trigger_error('Dayofweek index out of range', E_USER_ERROR);
    }
  }
  function isInbounds($n) {
    return (-1 < $n && $n < count($this->a));
  }
  function getDow1based($n) {
    return $this->getDow($n-1);
  }
  function getDowTolerant($n) {
    if ($this->isInbounds($n)) return $this->a[$n];
    else return "";
  }
}
