How many cities can I add?

As many as you like. Each city appears as its own row on the timeline, and you can remove any of them with the cross button.

How do I convert a specific time?

Click the hour you care about in any row. That column is highlighted across every city, and the summary below shows the matching local time and date for each zone.

Does it handle daylight saving time?

Yes. Times are calculated with your browser's time-zone data, so daylight saving offsets are applied automatically for each city and date.

Can I plan for a future date?

About the Time Zone Converter

The Time Zone Converter lets you line up as many cities as you need on a single horizontal timeline, so you can read across and see what time it is everywhere at a glance. It is ideal for planning calls, flights, live streams and messages to friends and colleagues abroad.

Each row is a city and each column is an hour of the day. Click any hour and the tool highlights that exact moment across every zone, giving you an instant conversion. Daytime and night-time hours are shaded so comfortable meeting times jump out.

Set any of your cities as home, change the date to plan ahead, and switch between 12 and 24-hour display. Everything runs in your browser and correctly accounts for daylight saving, so nothing you plan is uploaded anywhere.
