Navigation Within Events+

On my Events page I am showing a Calendar.

How do people navigate to a different month? There is a very small "prev" and "next" at the bottom of the page, but I need them to be able to select, for example June 2017 or December 2017 without having to go to the bottom of the page and keep going next, next, next, next, next, etc.

Where is the navigation for the calendar please?
