noun
Refers to the band of the sky through which the sun, moon, and planets appear to move, divided into twelve signs. Used in astronomical and astrological contexts.
黄道帯は十二の星座に分けられている。
The zodiac is divided into twelve constellations.
十二宮 refers to the twelve astrological signs themselves, whereas 黄道帯 is the band or belt of the zodiac.
Compound of 黄道 (こうどう, 'ecliptic') and 帯 (たい, 'belt' or 'band'), literally 'ecliptic belt'. The term is a direct calque of the Western astronomical concept.
