I know that Ukrainian language is not so widely used as russian but I can help you to translate plagins for this language. If it interesting, please send me your e-mail and I will send to you the first one tomorrow. Thanks.Correct Answer
Thank you for volunteering. We do not yet have a Ukranian translation for The Events Calendar and Events Calendar PRO. I would love to have you translate those plugins. Check out the Getting Started post where you’ll find the instructions and files you need. You will need to post the finished files here when you are done. We do not accept translation files via email. Thank you for your understanding.
