-     * <li>['^03'] would disable every day in every March</li>\r

-     * Note that the format of the dates included in the array should exactly match the {@link #format} config.\r
-     * In order to support regular expressions, if you are using a date format that has '.' in it, you will have to\r
-     * escape the dot when restricting dates. For example: ['03\\.08\\.03'].\r
