Tijdzone Converter

Overview

Set one reference time, live or any date you choose, and every zone you add shows its local time, the day there and its offset. Daylight saving time is handled for you. A world map shades where it is night, and each zone opens to show sunrise, sunset, golden hour and the moon phase.

How it works

Set your reference time

Use the live clock or pin a date and time, then set your home zone by city search or geolocation.

Add the zones you care about

Each zone shows its local time, whether it is today or tomorrow there, and its offset from home.

Read the day, night and sun data

The map shades where it is night, and each zone's daylight bar opens to show sunrise, sunset, golden hour and moon phase.

Frequently asked

How accurate are the timezone conversions?

Very accurate. Daylight saving time is handled automatically, using your browser's built-in timezone database.

Can I see sunrise and sunset times for a zone?

Yes. Expand a zone's daylight bar to see sunrise, sunset, solar noon, day length, golden hour and the moon phase, worked out for that zone and your reference date.

What does the day/night map show?

It shades the parts of the world that are in night at your reference moment and marks where the sun is directly overhead. Your zones are pinned on the map, so you can see who is in daylight.

Is my location data stored or tracked?

No. Everything is calculated in your browser, and your location is never stored or sent anywhere. Your zone list is saved only in your browser's local storage.

How many timezones can I compare at once?

As many as you like. Add or remove zones and change your home zone at any time, and your setup is remembered for next time.

Does the tool work for historical dates?

Yes. Pick any date and the tool applies the daylight saving rules and timezone changes that were in force then.
