Interestingly it lets see both the iOS and Material Design versions of the component. iOS has a strange combination of arrows to handle the month: right to expand the months dialog, down to close it. It took me a while to understand that the down arrow would bring me back to the calendar. Why not right and left? Maybe it is how it works on a Mac too. MD and anything else I remember has a down arrow to expand and an up arrow to close.
