Date Picker

Is is possible to change the appearance of the date picker?

I would prefer months to be numeric, - (minus) at the top and + (plus) at the bottom.

you can't change that in the default data picker

alternatively you could use a webviewer solution, 

see for example Juan Antonios solution here AI2. JavaScript. Nice DatePicker with Pikaday.js

or see my old datepicker example here

A Date Picker with App Inventor, HTML and jQuery UI

as suspected. I will look at web based date pickers more in line with what I want.
