A calendar that knows about time zones

Read a month, a week or an agenda, and move events between zones without the arithmetic. Import an .ics file to look at it, or export what you build here.

An event has a zone, not just a time

A meeting at 3pm is not a fact until you say 3pm where. Events here carry their zone, so an event created in one place still means the same instant when read from another — which is exactly what breaks when a calendar stores a bare wall-clock time.

.ics is the format everything already reads

Import an .ics to inspect it and export one to take it anywhere. It needs no account and no connection to another provider, which makes it the honest starting point — connecting directly to somebody else’s calendar is a different feature with a different cost.

Questions

Do I need an account?

No. Every timer, stopwatch, clock, converter and calendar view here works signed out, with no email and no limit. An account exists for three things only: keeping your saved timers across devices, an alert that reaches you with this tab closed, and subscribing to a calendar.

Is my data sent anywhere?

Timers, laps and clock choices are held in your own browser and are not sent to us. If you sign in and save something, it is stored against your account so it can appear on another device — that is the point of saving it.
