     * Basic structure of a holiday formula:    "type:modifier"
     * Basic rule: The Fixed holiday type "F" needs day and month modifier seperated by ".", 
     * all others an int offset value.
     * 
     * F:25.12      => Fixed holiday on 25 Dec.
     * E:-49        => Floating holiday 49 days before Easter Sunday
