Where this comes from

Checked against the sponsor: Yes. The rule on this page was read off NRAU's own published rules. Link last confirmed 2026-08-21.
What the source says: sactest.net/blog/rules/, the contest's own rules: 'CW: 16-17 September 2023 (3rd full weekend of September each year)'. 'Starts 12:00 UTC Saturday and ends 11:59 UTC Sunday.' Frequencies: '3510-3560, 7000-7040, 14000-14060, 21000-21070, 28000-28070 kHz' Exchange: 'The contest exchange consists of RS(T) plus serial number sequence starting with 001 (e.g., 59(9) 001).' Organiser: 'The Nordic Radio Amateur Union (NRAU) is the organizer of the contest.' Deadline: 'Cabrillo logs shall be uploaded no later than 5 days after the end of the contest, at 23:59 UTC.'
Recorded caveats: FOUND BECAUSE A BLOCKED ORGANISATION STOPPED BEING ASKED WHAT ELSE IT RUNS. NRAU is recorded in this registry as blocked, correctly: nrau.net says its contest information is under revision and publishes no rules for NRAU-Baltic or the Nordic Activity Contests. But NRAU also organises this, its flagship, and it publishes complete rules at a domain of its own. SAC appeared nowhere in the registry at all until the 2026-08-21 gap audit. THE PAGE IS HEADED 2023 AND THE RULE IS STATED AS STANDING. The recurrence sentences say 'each year', which is the form this catalog trusts -- the same form ARRL's generic calendar uses -- and they reproduce that page's own 2023 dates. Re-read when NRAU publishes a newer edition.

Add to Google Calendar Subscribe (iCal)This record as JSON

Add to Google Calendar puts the next running in as a single event. It is one event, not a subscription — come back for the one after it, or use the feed below.

Subscribe (iCal) carries this contest's runnings for the next twelve months as UTC instants and keeps them current. Apple Calendar, Outlook and Thunderbird take this address directly. Its identifiers are stable across deploys, so re-subscribing does not duplicate anything: https://contestclock.com/api/ics?id=sac-cw

Google has no working one-click subscribe. Paste that address into Settings → Add calendar → From URL. Google then polls it on its own schedule, often 8–24 hours, and that cannot be forced — so use Add to Google Calendar above if you want the next running in your calendar now.
