jQuery calendar/date picker

How do I place a date picker in my website, like http://www.avi开发者_开发问答s.co.uk/?

Look at jQuery UI, http://jqueryui.com/.

It supports a date picker.

Not the same, but you can try one of following:

1. jQuery UI -- datepicker
2. keith-wood.name_datepick

I hope this helps.

For more, search on the Internet. You will easily find lots of jQuery plugins available for free out there.
