Add Hebrew Date using a custom field

Following instructions are the product of a forum discussion taken in Drupal Israel site: http://www.drupal.org.il/node/3749 and are based on Mooffie's code with help from Yuval Hagger.

1. In Computed code paste the code that you find here:
http://drupa.co.il/_files/forexternsites/drupal.org-node-622098.txt

2. In Display format paste this:

<?php
$display = $node_field_item['value'];
?>

3. If you choose to store it in the database, varchar with 25 characters will be fine.

Note: For English names and calculation of the Jewish data look inside the code for "ELUL".
