Where this comes from

Checked against the sponsor: Yes. The rule on this page was read off ARRL / IARU's own published rules. Link last confirmed 2026-08-21.
What the source says: ARRL's Generic ARRL Contest Calendar at arrl.org/contest-calendar, which is ARRL stating the recurrence of its own contest in words: 'The second full weekend of July, 1200 UTC Saturday through 1159 UTC Sunday.' Re-verified 2026-08-21 against the stored rule, which matches. The Contest Corral on the same page is NOT a source here -- ARRL states it is generated from WA7BNM Contest Calendar data, so it is derived. Previous note read: 'ARRL: second full weekend of July'.

Something wrong? How to report it — a link to the sponsor's own page is all it takes.

Take it with you

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=arrl-iaru-hf

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.
