How to convert time zones online
A time zone converter shows the same moment in more than one city. Use names like America/New_York, not a frozen “EST” label. EST ignores daylight saving. Offsets on this page come from your browser for the instant you picked, so they change across DST.
Examples
Valid - Zone id
Europe/Berlin Invalid - Not a zone
GMT+2Frequently Asked Questions
How do I convert time zones online?
Paste a time or “now”, then pick cities such as New York, London, or Tokyo. You see local time and the offset for that date, including daylight saving.
Why is the zone missing?
The list is what this browser ships. Very old engines may have a short fallback list.
What happens in a DST gap?
Local clocks skip an hour in spring. A local time in the gap may be adjusted by the engine. Prefer UTC for stored events.
Tips
- Filter the zone box by city name (Chicago, Singapore).
- Airlines and calendars still surprise people around DST weekends. Recheck those dates.
