Sometimes you force the sun by hanging the rays yourself. On June 18, the shopkeepers of the Drieslag shopping center invite everyone to the Sunshower Picnic to celebrate the sun together! This celebration symbolizes a new year and honoring the light. On (almost) the longest day of the year, June 21. The importance of new holidays is not something new. Rituals change, just as society changes. Parties express our culture, shared values and thus our identity.
