Time Zone Converter - Compare Times Around the World

What this time zone converter does

This tool converts a date and time from one time zone to another. It shows the local time in both zones, the UTC offset for each, and the difference between them. It also tells you when the converted time falls on the next or previous day. Use it to plan a call, schedule a flight, or check when an online event starts where you live.

How to convert a time zone

1. Choose a date and time. These are the local wall-clock values in the "From" time zone. The page starts with the current time in your browser's zone.
2. Pick the from and to zones. The list uses IANA names such as America/New_York and Europe/London.
3. Read the result. The large time is the target zone. The cards below show both zones, the offset, and the difference.
4. Use Swap zones to reverse the conversion while keeping the same moment in time.

Tips for scheduling across zones

• Daylight saving changes happen on different dates in different countries. Check the result for the actual date, not just today.
• Add a buffer around calls and travel. A time that looks convenient in one zone may be late at night in another.
• The IANA database is maintained by the browser. Very old or future dates can follow rules that differ from today's.
• UTC is a useful reference because it has no daylight saving changes.

When to use it

Use the converter for international meetings, remote work, travel itineraries, live streams, and customer support hours. The result is an estimate based on time zone rules; for legal or transport deadlines, confirm with the official source.
