I don't know if my information is correct, but it would appear that the German youth celebrations took place every year at the summer solstice in June. Each Gebiet organized the event in the countryside and the festivities ended with a huge campfire.

That's right Eric. The games usually (but not always) took place on the weekend closest to the 21st of June each year. The Sonnenwende ceremony with the fire was usually a joint affair with the SS, SA etc.
