Where this comes from

Checked against the sponsor: Yes. The rule on this page was read off ARI's own published rules. Link last confirmed 2026-08-18.
What the source says: ari.it/contest-hf/contest-4080.html: '3) Data ed orario: il contest si svolge il secondo weekend completo di Dicembre con inizio alle ore 1300Z del sabato e termine alle ore 1259Z della domenica. L'edizione 2025 avra luogo il 13 e 14 Dicembre.' Bands are 40 and 80 metres; modes CW, SSB and RTTY; exchange 'RS(T) + la sigla automobilistica della provincia'. Sponsored by 'La Sezione ARI di Bologna, con il supporto dell'ARI Nazionale'. Logs are due within 6 days of the end of the contest.
Recorded caveats: As of 2026-08-18 the page still described the 2025 edition; the recurrence and times are stated as standing rules and are what is encoded. SWL entrants have a longer operating window than transmitting entrants (59 hours), which this record does not model -- the stored window is the transmitting one.

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

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=ari-40-80

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.
