How to use
- 1Enter a date and time and the time zone it's in.
- 2See the matching time in every city; working hours (9:00–17:00) are marked.
How it's calculated
The local time is converted to UTC using the zone's rules for that date (including daylight saving), then shown in each other zone with the browser's time zone database.
Frequently asked questions
Does it handle daylight saving time?
Yes — each zone's rules for the chosen date are applied, so a meeting in March or October shows the right times even when clocks change on different dates.
What's the difference between GMT and UTC?
For everyday use they're the same time. UTC is the precise scientific standard; the UK uses GMT in winter and BST (UTC+1) in summer.
How do I find a good meeting time?
Look for rows marked 'working hours' in every city you need — overlaps between Europe and the US West Coast are usually only early morning in California.
