When is Jin Yao Day?

Jin Yaori is Saturday. In ancient times, China called the sun, moon, fire, water, wood, gold and the seven stars of the earth obsidian (meaning bright and shining). Therefore, when the names of these seven stars are assigned to seven days in a week, they are called Japanese Obsidian Day, Moon Obsidian Day, Fire Obsidian Day, Water Obsidian Day, Obsidian Day, Golden Obsidian Day and Earth Obsidian Day respectively.

This is the last day of the week. It is named after Saturn, the god in charge of agriculture and the father of the Roman god Jupiter. It is also the only day in English where the name of the week is directly named after the god in Roman mythology, and the rest days are named after the god in Nordic mythology.
