Time Zone Converter & Meeting Planner
Convert an exact date and time between major world time zones, automatically accounting for daylight saving time where your browser supports current IANA rules. Compare working hours and copy a clean meeting summary.
Convert a Meeting Time
How it works
The tool converts your selected local date and time into a single UTC instant, then formats that instant in each selected IANA time zone. This lets daylight-saving rules change automatically for future or past dates where your browser has current time-zone data.
| Region | Included zones |
|---|---|
| United States / Canada | New York, Chicago, Denver, Los Angeles, Toronto, Vancouver |
| United Kingdom / Europe | London, Dublin, Paris, Berlin |
| Asia / Middle East | Karachi, Delhi, Dubai, Singapore, Tokyo |
| Australia / New Zealand | Sydney, Melbourne, Perth, Auckland |
Frequently Asked Questions
Does this handle daylight saving time?
Yes, the converter uses your browser's built-in IANA time-zone data for the exact date you choose. DST rules can change by law, so very old browsers may have stale data.
Why should I choose London instead of GMT?
London changes between GMT and British Summer Time, while a fixed GMT offset does not. Choosing the city zone gives the correct seasonal offset.
What counts as normal working hours?
This tool marks 9:00 AM through 5:00 PM local time as normal working hours for a quick planning check.
Is anything uploaded?
No. The calculator runs in your browser and does not require an account.
