I’ve posted a new version of Datecalc – Datecalc2 – which specifically supports the new Date picker control for iOS 5.x devices (e.g. iPhone 4S, and updated iPhones, iPads running iOS 5.x) . The older version of Datecalc is being maintained for backwards compatibility as well as the ability to run on non-iOS5 devices. If you are using a non-Touch screen device e.g. Google Chrome on your desktop, the spinning wheel datepicker is disabled.
Users are automatically redirected to a compatible version if they are not using the correct one.
