Where this comes from

Checked against the sponsor: Yes. The rule on this page was read off URE's own published rules. Link last confirmed 2026-08-18.
What the source says: concursos.ure.es/en/s-m-el-rey-de-espana-ssb/bases/: 'Sponsored by: Union de Radioaficionados Espanoles (URE).' 'Dates: SSB: 4rd full weekend of June, from 1200 UTC Saturday till 1159 UTC Sunday (June 27th and 28th, 2026).' -- URE's own typo, quoted as written; the ordinal is four. 'Bands: 10, 15, 20, 40, 80 and 160 meters, in the segments recommended by the IARU for this mode.' 'Logs must be received by 13th July 2026 (15 days).' That is exactly the stored end instant plus 15 days, so the number is encoded.
Recorded caveats: The fourth full weekend of June 2026 is 27-28 June, which is the date URE prints beside the rule, so the '4rd' typo does not leave the ordinal in doubt.

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=ure-rey-de-espana-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.
