Use Timer for a ten-minute break, Stopwatch to measure how long a task takes, and Alarm Clock for a reminder at a local clock time. For an event on a future date, set a Countdown.

Another city or a future meeting?

World Clock compares current times. Time Zone Converter converts a specific date and time, including date changes. Meeting Planner looks for a time that fits working hours across your selected cities.

What sets the clock?

OxClock reads your device’s clock. Enable automatic date and time if it looks wrong. City offsets use your browser’s time-zone data; a difference you see today can change with daylight saving. Check the event’s actual date before arranging an overseas call.

Keep useful work on your device

Saved cities, preferences and notes normally stay in this browser. They do not sync through an OxClock account. Export important calendar notes before clearing site data. Browser alarms and audio can stop when a device sleeps, so also use a native alarm for essential reminders.
