The Stichting Abrahamdag Oosterhout (Oosterhout Abraham Day Foundation) has the objective to collectively celebrate the reaching of the fiftieth birthday by men who were born in the same year, regardless of nationality, skin colour, religion or ideology, during Abraham Day on the first Saturday of October. It is a feast of recognition with a fair dose of humour and self-mockery. Every year 350 Abrahams can take part. They come from all over the Netherlands, but also from surrounding countries and further away. An exchange programme has developed with the Jaartallendag (Age Set Day) in Leuven (Belgium). The programme of an Abraham Day consists of a number of elements: after the welcoming and registration, the opening takes place in the Basilica of St. John the Baptist, there is a reception at the town hall, a wreath-laying at the Abraham statue, a lunch, various activities and the day ends with a dinner and a party night with family members, friends and former Abrahams.
