Hey there Eugene. Thanks for the note here, and my apologies for taking some time to get you a response…the colleague of mine who I’d handed the reigns on this forum over to is no longer with us, so I’m just today catching up on what was missed since her departure. I really appreciate your patience so far.
Our plugin totally supports internationalized/translated sites, and looking through our records I see that we actually do have a Hebrew translation for The Events Calendar & Events Calendar PRO. While I cannot speak to the quality of the translations themselves (I didn’t create them and don’t speak Hebrew; we rely on translations to be provided by members of the community) they are indeed present.
Hope that helps. If you have any further questions on this end, do let me know and I’ll get you what you need.
