The current date selector on Special:CentralNotice is hand-crafted and this has several problems:

• It may require separate maintenance.
• It assumes the USA order of month, day, year.
• With an RTL interface language the order becomes even stranger: year, day, month.

It should be replaced by the jQuery datepicker, which is already used in at least two extension, is well maintained by its own and has pretty good internationalization.
