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=rsgb-iota

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.
