The date was changed? I thought it would be only 1 week
The date and duration of the YAZJams vary from year to year. For 2025, the jam was planned to last three months, starting on August 15th. This allows, after the jury votes, to send out the awards during the Christmas period. This is new, and next year it will probably be different. These YAZJams are a real mystery! But nothing has changed since the jam page was first published. So, no dates have changed.
