About Friendly Orbit
Small tools for keeping in touch when your people live on different clocks.
What it is
Friendly Orbit has five free tools: a meeting planner that lays everyone's day side by side, a friends' world clock, a best call time finder, a time zone converter and a list of daylight saving time change dates. They are made for families spread across continents, friends who moved abroad and small groups that meet online, so there is nothing to sign up for.
How it works
Every calculation runs in your browser. Time zone rules come from the copy of the IANA time zone database built into your browser, read through the standard JavaScript Intl interface, and the list of cities is part of the page. Nothing you type is sent to a server, and once a page has loaded it keeps working offline.
How accurate it is
As accurate as your browser's time zone data. Governments sometimes change their clocks at short notice; browsers pick up those changes with their regular updates, so keep yours current. For anything important, such as a flight or an exam, confirm the time with the organiser.
Who makes it
