Hey Carl,
Our plugins are fully translatable using the basic methods of translating a WordPress installation—if you’re not familiar with how to do this, I would recommend researching online for “How to use WordPress in another language.”
I would also recommend reading these three knowledgebase articles that cover how to translate our plugins specifically:
• Translating The Events Calendar: http://theeventscalendar.com/knowledgebase/translating-the-events-calendar/
• Translating our premium add-ons: https://theeventscalendar.com/knowledgebase/adding-or-updating-a-translation/
• Changing the language on your site: https://theeventscalendar.com/knowledgebase/changing-the-language-on-your-calendar/
Cheers!
George
