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: contest.ari.it/hf_web/rules/aridxrule_dx.pdf. Italian text, 3) Data ed orario: 'Il contest si svolge il primo weekend completo di Maggio con inizio alle ore 1200Z del sabato e termine alle ore 1159Z della domenica. L'edizione 2026 avra luogo il 02 e 03 Maggio.' English text: 'The contest will be held on each first full week-end of May starting at 1200Z Saturday and ending at 1159Z Sunday. In year 2026 the dates will be May 02-03.' Bands 'from 10m through 80m, except WARC'; modes CW, SSB and RTTY. Italian stations send RST + province, others RST + progressive number from 001, and 'no QSO/HRD between Italian station are permitted'. Logs are due 'no later than 6 days after the contest'.
Recorded caveats: The rules PDF is the sponsor's own; ari.it/contest-hf/ari-international.html carries results rather than rules, and ARI's contest calendar page is an aggregator listing other sponsors' events, so neither was used as a source for anything beyond ARI's own contests.

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-international-dx

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.
