"Tuesday is a weekday."
Translation:Tirsdag er en hverdag.
So, I thought I was going to be confused by this, since the very first time I saw this I immediately assumed Thursday (which is torsdag). But it actually makes perfect sense, if you know the etymology. Tuesday is Týr's day (or Tiw in Old English), and Thursday is Thor's day.
Týr's day = tirsdag
Thor's day = torsdag
