How to override the JQuery Datepicker to return today’s date

I support an ASP.net application that has multiple pages with fields that prompt for a date. All of our date input fields use the JQuery Datepicker calendar pop-up control to allow the user to select a date from the calendar.

The datepicker pop-up control can be defined to show several options (reference: JQuery Datepicker for details). One of those options is a button for today. When the today button is clicked the calendar control re-positions to the month containing today’s date. Many users wanted the today button to select and return today’s date to the date input field. This can be easily accomplished with a simple override.

Paste the following script in each page that loads the JQuery datepicker control, or better yet load it globally.
