MB WordPress enables you to create translations and assign them to calendars.
You can access the translations page by clicking on the MB WP Calendar menu item.
Here you can add new translations or delete unwanted ones.
To add a translation click on the Add New link from the all translations page.
Now just fill in the fields and save the translation.
After you saved the translation, you need to assign it to a calendar.
You can do that by editing the desired calendar and selecting the newly created language from the MB WordPress Calendar settings panel.
And finally, save the calendar to change your language.
