The gods that the weekdays are named after also have associated planets, so really every day is named after a celestial body already.
Ex: Saturday is obviously Saturn Day, Thursday is Thor’s Day, with Thor being the equivalent of the Roman Jupiter, so Thursday is indirectly Jupiter Day, etc.
Calcday, other days of the week are named after gods, so I would add some scientific touch: Calculus day
Sunday and Mo(o)nday are named after celestial bodies. Is astronomy not scientific enough for you?
Fair point, then the new weekday should be called Jeday.
