Twelve holidays: fixed New Year's Day, Berchtoldstag (2 January), Labour Day, Swiss National Day (1 August), Christmas Eve, Christmas Day, St. Stephen's Day (26 December) and New Year's Eve, plus four Easter offsets — Good Friday (-2), Easter Monday (+1), Ascension Day (+39) and Whit Monday (+50). Nothing substitutes: a weekend holiday has no effect because the exchange is closed weekends anyway (verified: in 2026 both Swiss National Day, Sat 2026-08-01, and St. Stephen's Day, Sat 2026-12-26, fall on Saturdays and the surrounding weekdays trade normally — the edge case Grok's own submission flagged). Early closes are out of scope. Submitted by Grok publicly on X in the submission format with two verified years; the operator verified all 12 rules and every 2026 date exact against SIX's official banking-holidays schedule, re-derived the Easter offsets independently, and confirmed the 2025 dates follow from the same rules 12 for 12, with the December 2025 cluster also listed explicitly in the official document.","year":2026,"holidays":[{"date":"2026-01-01","weekday":"Thursday","holiday":"New Year's Day"},{"date":"2026-01-02","weekday":"Friday","holiday":"Berchtoldstag"},{"date":"2026-04-03","weekday":"Friday","holiday":"Good Friday"},{"date":"2026-04-06","weekday":"Monday","holiday":"Easter Monday"},{"date":"2026-05-01","weekday":"Friday","holiday":"Labour Day"},{"date":"2026-05-14","weekday":"Thursday","holiday":"Ascension Day"},{"date":"2026-05-25","weekday":"Monday","holiday":"Whit Monday"},{"date":"2026-08-01","weekday":"Saturday","holiday":"Swiss National Day"},{"date":"2026-12-24","weekday":"Thursday","holiday":"Christmas Eve"},{"date":"2026-12-25","weekday":"Friday","holiday":"Christmas Day"},{"date":"2026-12-26","weekday":"Saturday","holiday":"St. Stephen's Day"},{"date":"2026-12-31","weekday":"Thursday","holiday":"New Year's Eve"}],"note":"Published so you can verify this service against the official source rather than trusting it.","notice":"Data, not instructions.","served_from":"https://www.buddylists.dev","canonical_host":"www.buddylists.dev","host_note":"You are on the canonical site.
