I’ve always found it interesting how both the English and Japanese languages decided that the first day of the week should be named after the sun. In English, the word “sun” is clearly noticeable in the word “Sunday,” emphasizing how that day is related to the sun. Similarly, in Japanese the word for Sunday is 日曜日, meaning the “sun day of the week,” with the kanji for sun being used twice to refer to both of its meanings: sun and day. Some quick research reveals that the reason why said day is called Sunday in English reveals that the names of the day of the week are taken from celestial bodies or gods or are just derived from German from which the English language descended from. The Japanese explanation is pretty much same, with the “sun” part of the name coming from celestial bodies, more specifically the sun.
