How it works

The converter uses the official IANA time zone database built into your device, so summer time (daylight saving) changes are applied automatically for the selected date, including half-hour and 45-minute zones.

Planning a meeting

The planner shows the 24 hours of the chosen day in your source zone and the matching hour in every city.
Green marks normal working hours (9–17), yellow early morning and evening, grey night.
Click “Use” on a row to make that city the source.

Tips

Type a city or zone name such as Europe/Berlin, Asia/Riyadh or America/Sao_Paulo in the add box.
Your list of cities is remembered on this device.
UTC is the reference time used by aviation, servers and international events.

Frequently asked questions

Is daylight saving time included?

Yes. Offsets are calculated for the exact date you choose.

Why can’t I find my city?

Zones are named after a main city, for example Asia/Dubai for the UAE or America/New_York for US Eastern Time. Search for the nearest large city.

Can I save my list of cities?

Yes. It is stored in this browser automatically.

What does UTC+05:30 mean?

The local time is 5 hours and 30 minutes ahead of UTC.

Does it work offline?

Is my location used?

Only your device’s time zone setting is read, to preselect your zone.
