From Rarotonga to the rest of the week

See the hours you actually share.

Island Hours is a timezone overlap calendar for people in the Pacific who work with clients in New Zealand, Australia, the United States, and the United Kingdom. It uses real IANA time zones in your browser — including daylight saving — so you are not guessing offsets on a napkin.

Default home zone is Pacific/Rarotonga (UTC−10). Add Auckland, Sydney, Los Angeles, London, or any IANA city. Set work windows. Get two or three meeting times with both local clocks, then copy a plain-text note.

$19 USD, one-time

Tax may be added at checkout by Paddle, the merchant of record. No subscription. You keep the static app; it runs on your machine.

What it does

Built for the date line, not for a generic “world clock” screenshot. Your Wednesday morning in Rarotonga is already Thursday in Auckland — the bars show that, instead of making you hold it in your head.

Your lagoon, their office

Set home to Rarotonga (or any IANA zone) and one to four counterpart cities. Work windows default to 08:00–17:00 local and are editable on each side.

Today and the next seven days

A 24-hour bar for each day: your hours, theirs, and the teal overlap. Daylight saving is handled by the browser’s IANA data — no hand-maintained offset table.

Slots you can send

The best two or three meeting windows, with every local time. Copy a message that starts “I’m in Rarotonga (UTC−10). Best overlap this week: …” Print a simple week if you want it on paper.

Who it is for

Pacific people with distant clients

Freelancers, studios, and remote staff in the Cook Islands, and neighbours across Polynesia, who book calls with NZ and AU agencies or US and UK teams. Built so the home clock is the island, not California.

Anyone tired of converting by hand

If you already live in Auckland or Sydney and only talk to London, this still works — pick any IANA timezone. It will not promise you more hours in the day. It will show the ones you share.

What it is not

Not a marketplace, not a course, not financial advice, and not a “passive income” kit. It is a small static website you can open locally or host on any HTTPS static host. Checkout, when connected, is handled by Paddle.
