- * <li>['^03/08'] would only match the beginning (useful if you are using short years)</li>
- * <li>['03/../2006'] would disable every day in March 2006</li>
- * <li>['^03'] would disable every day in every March</li>
- * </ul>
- * Note that the format of the dates included in the array should exactly match the {@link #format} config.
- * In order to support regular expressions, if you are using a date format that has '.' in it, you will have to
- * escape the dot when restricting dates. For example: ['03\.08\.03'].
