skärtorsdagen = Maundy Thursday
Skansen, the open air museum is still open, with free admission for kids who dressed as a witch today. These are rather cute witches; photos below from Skansen's website.
We didn't go- still avoiding crowds for obvious reasons. Skansen is asking its patrons to stay as far apart as they would from a moose- seems like a reasonable distance.
This is also the day that one is supposed to put out birch bark branches with little feathers on them; photo from this site.
Swedish word of the day: skärtorsdagen
