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.
Rephrasing to specific task of changing to to use jquery.ui.datepicker module (instead of "a jQuery datepicker").
Here's an attempted fix. The date should be correctly internationalized, thanks for the report!
