- Friday is defined as a day you are working but have the following day off.
- Saturday is defined as a day you are off but have the following day off.
- Sunday is defined as a day you are off but are working the next day.
Given these irrefutable axioms, if you were to add a second Sunday to the week, one after another, the first Sunday would react violently to the second Sunday and be converted into a Saturday.
Double Saturdays, though? Completely possible. And that's why Saturday is considered a Noble Day.
monday is defined as a day where you did not work yesterday, but you work today
wednesday is defined as a day where you worked yesterday, are working today, and will work tomorrow
tuesday and thursday are just wednesdays in a trenchcoat and/or groucho marx glasses
thursdays are actually their own day, the day before friday
tuesdays are definitely wednesdays in a trenchcoat though.
