Dear maksim1976.
Thanks for getting back to me.
You need to select a language from the admin panel. According to this calendar will automatically work in the language you want. And if you want the events to beat in your language too. You just have to write in whatever language you want. Our plugin supports all languages.
You can do it with this plugin.
You can try using the Loco Translator plugin for this. Download the plugin from here and please refer to the screenshot below if there is any confusion on how to use the plugin.
