Windows Uri Launch Calendar app with NFCtag

I'm stuck and can't find any solutions online jet for my problem.

What I want is to write a WindowsUri to an NFC tag wich will launch the default calendar app on a Windows or Windowsphone device. I'm not sure if this is even possible, but launching skype, or making a new contact for example is possible.

The example below writes a skype call URI to an NFC tag wich will launch skype and call the defined user when tapping a scanner. So what i'm looking for is a similar idea to launch the calendar app

using( var writer = new DataWriter
        {
            UnicodeEncoding = UnicodeEncoding.Utf16LE
        } )
        {
            // Prepare the message to be published.
            writer.WriteString("skype:echo123?call");
            var buffer = writer.DetachBuffer();

            // Publish the message. You must tap an NFC tag to your device to write 
            // the content to it.
            long id = proximityDevice.PublishBinaryMessage( "WindowsUri:WriteTag", buffer );
        }
