Where this comes from

Checked against the sponsor: Yes. The rule on this page was read off CRAEC's own published rules. Link last confirmed 2026-10-15.
What the source says: cvadx.org/regulamento (updated 03/08/2026, 67th edition): 'Quarto final de semana de agosto'; 2026 SSB 22 Aug 1800 UTC to 23 Aug 2100 UTC; log deadline 28 Aug 23:59 UTC. Read 2026-10-15.
Recorded caveats: 'Fourth weekend' read as the ordinal full weekend; counted from the month's end it would be 8-9 August, so the stated 2026 dates fit only the ordinal reading.

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=cva-dx-ssb

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.
