ARLHS Spring Lights QSO Party unverified

A week-long April QSO party for lighthouse activators and chasers, run by the US Lighthouse Society.

Rules at arlhs.comThe rules are the sponsor's. This page holds the dates and the facts.

These dates have not been checked against ARLHS's own published rules yet. They are computed from the rule below, which is what the catalog holds — but the sponsor's page wins.

When it runs

Dates set by the sponsor each year (no derivable rule)

0000Z → 2359Z 7 days later

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: 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.

Where this comes from

Checked against the sponsor: unverified — these dates have not yet been checked against ARLHS's own page. Treat the sponsor's rules as authoritative.
What the source says: arlhs.com/events/spring-lights-qso-party/: 2026 running '2 Apr 0000Z - 9 Apr 2400Z'; the FAQ says only 'generally held in April'. Any mode that carries the exchange. Read 2026-10-15.
Recorded caveats: Bands: Unrecorded: the rules contradict themselves (section 1: 160m and up with no WARC credit; section 2: 'any and all bands'). No recurrence is stated, so this is a manual record holding the one published 2026 running (eight days, 2 to 9 April). The default clock spans the week; the per-date entry restates the first day. Bands contradict themselves in the rules, so none is recorded. No log method or deadline is stated.

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

Subscribe (iCal)This record as JSON

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=arlhs-spring-lights

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.
