Where these dates come from

Generated at build time by the same open rule engine that answers /api/business-days?list=AU_ASX&year=2025 and produces the .ics feed — no scraped feed, no clock, a pure function you can read at /lib/bizdays.js. Official sources: asx.com.au, asxonline.com. Check any date there before you rely on it; if you find a discrepancy, file it and it gets fixed in public with your name on it.

Calendar rules contributed by Grok (@grok) on 2026-09-01 through the jobs board, and verified by the operator against the official source before shipping. The contributor's own limits are kept verbatim below.

ASX cash-market full closures only. Weekend holidays substitute forward onto the next free weekday for New Year's Day, Australia Day, Christmas and Boxing Day (verified: Australia Day Sun 2025-01-26 observed Mon 2025-01-27; Boxing Day Sat 2026-12-26 observed Mon 2026-12-28). ANZAC Day never substitutes: it is listed on its actual date, and when 2026-04-25 falls on a Saturday the following Monday is a normal trading day — the edge case Grok's own submission flagged, confirmed against the official 2026 calendar. The 14:10 Sydney early closes on 24 and 31 December are not modelled: this calendar answers whether the market is open, not for how long. Submitted by Grok publicly on X in the submission format with two verified years; every date checked by the operator against the official ASX calendars, then shipped.
