The Korean calendar is fairly simple. Simply place a new word in front of 요일(yo-il), which in English is translated as “day.” The word “요일(” is actually derived from Latin, just like the word “English,” and this technique is still employed in Japan and Korea today.
Thus, the Chinese five elements of nature (fire, water, wood, gold, and earth) as well as the sun and moon are the source of the meaning of the days of the week in Korean.
