It’s Midsummer Day throughout most of Europe.
It should not be confused with the Summer Solstice (or the Swedish horror film) except they’re kind of celebrating the same thing.
Somehow this all ties into June 24, 1374

In a sudden outbreak of Dancing Mania (aka St. John’s Dance), people in the streets of Aix-la-Chapelle, Prussia experience terrible hallucinations and begin to jump and twitch uncontrollably until they collapse from exhaustion.
Many of the sufferers are afflicted with frothing at the mouth, diabolical screaming, and sexual frenzy. The phenomenon lasts well into the month of July. Nowadays, ergot madness is suspected as being the ultimate cause of the disorder.
(Please refrain from mentioning raves.)

(it’s also the feast day of St. John the Baptist.)
Upon further thought, avoid all parties throw by Northern Europeans today
Demand Euphoria!
