Swensday 

Ahh swensday, the one day of the week dedicated to soley wearing sweaters. Swensday happens to fall on a Wednesday every week. Swensday is known to have started back in the middle ages with King Swensday IV and has since become incredibly popular amongst high school students in public schools.
