I guess if you are competent in both it's doesn't really matter though I'd think jQuery would be better as you'd have less cross browser incompatabilites to deal with etc. Also I'd look at the Date Picker in jQuery UI (http://jqueryui.com/demos/datepicker/inline.html). I have played/hacked about with it in the past and manged to get the inline version to span an entire screen. With a bit more work you could extend it.
