Thank you for sharing this, Roni!
We actually no longer manually implement translations—translations are community-driven, with some approval/moderation support from us of course.
To learn about sharing translations for both The Events Calendar and for any premium add-ons, check out these tutorials here:
• 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/
I hope these articles help!
