KCJ Contest
Japan's Keymen's Club CW contest in August: 24 hours where Japanese stations are the multipliers.
Rules at kcj-cw.comThe rules are the sponsor's. This page holds the dates and the facts.
When it runs
Dates set by the sponsor each year (no derivable rule)
- 1200Z → 1200Z the next day
Times are UTC, as the sponsor states them.
The sponsor announces these dates a year at a time and there is no rule to derive, so this calendar holds only the years they have published: 2023, 2024, 2025, 2026.
Next runnings
The sponsor sets this date each year rather than by a rule, and has published through 2026. Years they have not announced are absent rather than guessed.

- What the source says
kcj-cw.com rules PDFs (<year>_<n>_kcj_dx_t.pdf) and contest_info page: CW, 1200Z Saturday to 1200Z Sunday; starts 2023-08-19, 2024-08-17, 2025-08-16, 2026-08-15 (47th). Log deadline 1500Z 31 Aug 2026, about 15 days after the end. Read 2026-10-15.
- Recorded caveats
- DATES ARE STATED PER EDITION; THE SPONSOR PUBLISHES NO RECURRENCE RULE. Only the dates the sponsor has actually published are encoded (2023-08-19, 2024-08-17, 2025-08-16, 2026-08-15); a year it has not announced yields nothing rather than a guess. If a stated rule turns up, this record upgrades from manual.
Something wrong? How to report it — a link to the sponsor's own page is all it takes.

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=kcj-contest
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.
