Time Zone Meeting Planner — 3pm my time is what time in Sydney, and is anyone joining at 4am?

Find an hour that isn't the middle of the night for somebody. It ranks every hour of the day by whoever has it hardest, so it never picks a time that suits three people by waking the fourth at four in the morning.

WHAT YOU GET

- Every city on earth, read from your browser's own time zone data — so it works offline

- A colour grid of the whole day, everyone's clock side by side

- Warns you when a date is already the weekend at one end of the call

- Tells you exactly when each country's clocks change, and by how much

- Ranked by the worst-off person, not by an average that sells someone out

HOW IT WORKS

1. Add a city per person — Type the nearest big city — the time is the same.

2. Say what counts as your working day — Nine to five, or whatever yours really is.

3. Pick from the top three — With everyone's local time and date next to it.

One file. Double-click it and it opens in the browser you already have — Chrome, Edge, Safari or Firefox. Nothing to install, no account, no subscription.

Nothing you type ever leaves your computer. There is no server involved, which is why it still works with the wi-fi switched off.

30-day refund, no questions asked.
