In 2006 the Archbishops of Utrecht and Canterbury celebrated together in Freiburg im Breisgau, Germany, 75 years of the Bonn Agreement in the context of the 29th International Old Catholic Congress (IAKK).
The Swiss Willibrord Society normally celebrates a "Willibrord Day" every year. This is normally in October or November, close to St. Willibrord's Day (7 November). In 2005 we did something more practical. Together with the Swiss Anglican chaplaincies, who were celebrating the 25th anniversary of the founding of the Anglican Diocese of Gibraltar in Europe, we invited all interested people to journey together on a number of pilgrimages.
