Does it account for daylight saving time?

Yes. It uses the IANA zone rules built into your browser, so an offset is computed for the specific date, not assumed to be constant.

Why use a city name instead of a UTC offset?

An offset like UTC+1 is ambiguous across the year — a city name resolves to a full rule set that knows when the offset changes.

Is my location sent anywhere?

No. Zone handling is entirely local to your browser.

Time & Time Zones

Add a time zone

Times come from your device clock; zone conversion uses the browser's own Intl engine. Nothing is fetched.

About Time & Time Zones

World clocks, time-zone conversion and a meeting planner that shows working hours across cities so you can find a slot that isn't cruel to anyone.

What it does

Track several cities at once, convert a moment from one zone to another, and use the meeting planner to see a whole day across every participant's zone side by side — including which hours fall inside a reasonable working day for each of them.

Daylight saving, handled properly

Zones are resolved through your browser's own IANA time-zone database rather than fixed UTC offsets, so daylight saving transitions are applied correctly for the date in question. This matters for meetings booked across a transition, when the gap between two cities changes by an hour partway through the month.
