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-cw/bases/: 'Sponsored by: Union de Radioaficionados Espanoles (URE).' 'Participants: Any licensed amateur station.' 'Dates: CW: 3rd full weekend of May, from 1200 UTC Saturday till 1159 UTC Sunday (May 16th and 17th, 2026).' 'Bands: 10, 15, 20, 40, 80 and 160 meters, in the segments recommended by the IARU for this mode.' 'High power ( Maximun legal limit in each country), Low power ( max. 100 watts ) and QRP (max. 5 watts).' 'Logs must be received by 1 June 2026 (15 days).' That is exactly the stored end instant plus 15 days, so the number is encoded.

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-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.
