How we check
Every date comes from the organiser's, the municipality's or the canton's own site — never from an aggregator, never copied over from last year. Next to each source is the date we last read it.
Where only a fixed rule is published, such as the eve of St Nicholas' Day, we work out the date and label it “calculated from the fixed rule”. Anything not yet published stays open — we don't guess.
Something missing or changed? A note below is enough; we check it at the source.
