How do I use the Time Zone Converter?
Select a reference date and time using the date/time picker, then add up to 6 cities from the dropdown. Each card shows the exact local time and date in that city, highlighted with a business hours indicator.
Which time zones are supported?
We support 38 major time zones covering every major city globally, including all US time zones, European capitals, Middle East, South/Southeast Asia, East Asia, Oceania, and African hubs.
Does it automatically adjust for Daylight Saving Time (DST)?
Yes. We use your browser's built-in Intl.DateTimeFormat API which automatically applies the correct DST offset for the selected date. So if you pick a summer date, US Eastern will show EDT (UTC-4) instead of EST (UTC-5).
How can I schedule a meeting across multiple time zones?
Enter your desired meeting time in the reference date/time field, add all participant cities, and the tool will instantly show what local time that corresponds to for each participant. Look for times where all zones show a green Business Hours badge (9am–5pm).
Is my data sent to a server?
No. All time calculations use your browser's native JavaScript Date and Intl APIs. No data is sent to any server, and the tool works offline once loaded.
