Add a city to start.
World clock
Keep the time of every city you work with in one view. Add cities from the full IANA time zone list, see analog and digital clocks with the UTC offset, day or night and daylight saving time, and use the meeting planner to find an hour that falls inside working hours everywhere. Add cities by searching any IANA time zone, reorder them with the arrows and rename them by clicking the name. Each city shows an analog and a digital clock, the UTC offset, day or night and daylight saving time. The meeting planner slider picks a time in the first city and shows the time everywhere, with working hours highlighted. Your cities and settings are saved in this browser.
How it works
- Search for a city or time zone and add it, then reorder the list so your own city comes first.
- Read the analog and digital clocks, the UTC offset, day or night and daylight saving time of each city.
- Drag the meeting planner slider to a time and check that it falls inside working hours in every city.
Always correct, also around daylight saving time
The clocks use the time zone rules built into your browser, the same IANA database that phones and servers use. When a city moves its clocks forward or back, the offset, the date and the meeting planner follow automatically, including zones with half hour and quarter hour offsets such as India and Nepal.
Plan meetings across time zones
The first city in the list is the reference. Pick a time today with the slider and every city shows its local time, the date and whether that moment is inside working hours. Hour strips mark working hours in green and the common working hours of all cities are listed below.
Frequently asked questions
Is the world clock free?
Yes. It is free, needs no account and works in any modern browser. Your cities and settings are stored only in this browser.
How does it handle daylight saving time?
Every time is calculated from the IANA time zone rules in your browser, so summer time starts and ends on the right day for each city. A badge shows whether a city is on daylight saving time or standard time.
Why does a city show tomorrow or yesterday?
Cities far to the east can already be on the next day, cities far to the west still on the previous day. The date next to each clock is compared with the reference city, the first one in the list.
