Viikonpaiva

Yesterday I began the arduous (as many tell me) process of learning Finnish. (As an interesting sidenote, there has been one person who disagrees with all of you as to the difficulty of the Finnish language. A patient at the office, who is a retired linguistics professor and a professional interpreter who speaks 58 languages, told me that pure linguistic Finnish is probably one of the most efficient and easy to learn languages in the world. Apparently it's just because Finnish is conforming to the expectations of most modern languages that makes it complicated.)
I now know the days of the week (Viikonpaiva) in Finnish. Today is Torstai. This Sunnuntai I wiil go to church. I had dinner with some friends on Keskiviikko this week. I'm looking forward to this Maanantai, when my holiday begins. Although, I have Perjantai off every week, so I guess it really starts on Lauantai. There's also Tiistai, which I couldn't think of a reference for.
See if you can sort out this mess and tell me the Viikonpaiva in order!
