Good evening Ron and welcome to the Events Calendar forum!
First off, I would like to apologize for the delay answering.
We are currently experiencing a higher level of requests than usual.
Please rest assured that we are working hard at correcting this situation.
We appreciate your patience while we try to normalize things.
Thank you for your interest in our products.
We’ll be glad to answer your questions.

I highly recommend reading the two following articles on translation:
You can see the status of our translations here: http://translations.theeventscalendar.com/projects/
Additionally our plugins can work with either WPML or Polylang to various degrees.
Let me know if that helps.
Have a great day!
Geoff B.
