The annual Christian youth festival EO Jongerendag celebrated its 50th anniversary on Saturday, June 6, 2026, at the Rotterdam Ahoy arena.
The event, which began in 1975, has grown into the largest worship gathering for young people in the Netherlands.

Festivities started on Friday evening with a massive worship concert for former attendees, followed by the main youth event on Saturday.
From Cattle Smell to Arena Spectacle
Former presenter Jan van den Bosch hosted the first 18 editions.
He recalled that the inaugural 1975 gathering took place in the Martinihal in Groningen, where the venue still smelled of cattle from a market the previous day.
"Friday afternoon, the cows were still being traded in the hall. Saturday morning, 4,000 young people stood there.
I sent some youngsters to all supermarkets in the city to buy air freshener. Then the air was a bit bearable," van den Bosch said.
He explained that the festival was created to reach younger generations during a period of shifting cultural values.
"It was the time of flower power, and the prevailing thought was that God was dead. Young people had little interest in faith.
I wanted to show that it was different," van den Bosch added.
As attendance grew, the event moved to larger venues, including the Arnhem Rijnhal, Galgenwaard in Utrecht, GelreDome, and the Johan Cruijff Arena.
Van den Bosch noted that safety regulations forced the relocation from Arnhem.
"We were in the Arnhem Rijnhal when the fire department told me they would no longer allow the height of the stands the following year," he said.
Core Message Unchanged
Current presenter Joram Kaat first attended the event as a high school student around 2008 or 2009. He described it as his very first festival experience.
"I was in high school, grew up in the church, and this was really a day out. It was truly my first sort-of festival experience," Kaat said.

Kaat persistently requested to work behind the scenes until the broadcasting organization Evangelische Omroep (EO) granted him access in 2009.
He recalled his early responsibilities during an appearance by a prominent American worship artist.
"I knew I wanted to go to Hilversum. I stalked the EO because I really wanted to go behind the scenes once.
But they kept brushing me off with all sorts of excuses," Kaat stated.
Kaat received a radio and a pass to observe the production. During the soundcheck, the drummer asked him to get a pillow.
"I had no idea what a pillow was. I turned around and called my brother," he related.
Kaat emphasized that while the modern production elements change to appeal to today's teenagers, the core message remains intact.
"The core of the day has been the same for fifty years, but the form has changed. We look carefully at what fits the teenagers of today.
This is a day entirely designed for them. Moreover, they are in a hall with like-minded people," Kaat observed.
Longtime contributor Maarten experienced the event as a visitor, volunteer, and employee over the years.
He reflected on how his personal history intertwines with the evolution of the gathering.
"You are not alone," Maarten stated.
Van den Bosch continues to attend the annual festival regularly despite his age.

"I am 75 now, but in my heart I still feel like a teenager," he remarked.
