The Sun does not get 18° below the horizon here tonight, so the sky never goes fully dark: these are the darkest hours there are.

Tonight here reads much as it does from Bayan Nur, China, whose page says it for both.
How it is worked out: the Sun, the Moon and the planets from the same ephemerides the sky map draws, for Ulan Bator at 47.91°N, 106.88°E, with a flat horizon and the light-pollution atlas’s estimate of its sky. Dark means the Sun 18° below the horizon; a planet counts once it is 10° up. The methods and their measured errors.
