Weekday names

Korean (and Japanese) weekday names are based on celestial/elemental system which is the classical “seven luminaries”.

In Korean, each weekday name = element + 요일 (yo-il, meaning “day of the week”):

• 월요일 (woryoil) — Monday → 月 Moon
• 화요일 (hwayoil) — Tuesday → 火 Fire
• 수요일 (suyoil) — Wednesday → 水 Water
• 목요일 (mogyoil) — Thursday → 木 Wood/Tree
• 금요일 (geumyoil) — Friday → 金 Gold/Metal
• 토요일 (toyoil) — Saturday → 土 Earth
• 일요일 (iryoil) — Sunday → 日 Sun
