Main sources
- Bilbao City Council's Aste Nagusia portal.
- Council press releases, used for new announcements, relocations and changes.
- The Kulturklik cultural listings, as a secondary public index of the programme.
Verification rules
- Where two sources disagree, the most recent council communication prevails.
- We do not infer times, prices, accessibility or routes from custom.
- Every event keeps its source, status and date of last review.
- A technical republish does not change the editorial date if the data has not changed.
Writing and rights
We summarise facts in our own words. We do not copy full press releases, posters, photographs, maps or audio without a licence. We link the original page so any reader can check the information.
Corrections
When something changes, we update the affected canonical page and flag the change if it could alter a visitor's plans. During the festival, always check the linked source before setting out.
