As you probably know, Nondag, Ondag, Pondag, Quondag, Rondag, Shondag and Tvondag are the days of the Ruritanian week. But I wonder if you know which is which.
Well, think of the week as starting with Monday. You can get three Ruritanian days right by calling out the alphabetical order above. That does not help much, of course, as you do not know which three. So her is another order which gets three right: Quondag, Ondag, Nondag, Pondag, Rondag, Tvondag, Shondag. And here is another which also gets three right: Tvondag, Quondag, Pondag, Ondag, Nondag, Shondag, Rondag.
That should be enough to go on. What is the fully correct order?
