Dato supports all the locales and languages that macOS supports for the menu bar text, dates, times, and the calendar, but the menus and preferences are English-only.

Dato gives you a local clock, date, multiple world clocks, and upcoming events in the menu bar. When you click Dato in the menu bar, you get a menu with a calendar, calendar events, and world clocks. All of this is highly customizable.
