Time zone converter
Pick a date and time in one city and see the same moment everywhere else — daylight saving included. Add up to eight cities and share the link.
How to convert a time between time zones
- Choose the city where the time is set — for example, where the meeting organiser lives.
- Enter the date and time there. The date matters: daylight saving time starts and ends on different dates around the world, so the gap between two cities can change by an hour for a few weeks each spring and autumn.
- Read the list. Each row shows the same moment in another city, with a tag when it falls on the previous or next day.
Why not just add the hours?
Adding a fixed number of hours works most of the year but fails around clock changes, and for places with half-hour offsets such as India (UTC+5:30), Newfoundland (UTC−3:30) or Adelaide (UTC+9:30 or +10:30). The converter looks up the exact offset each city uses at that particular moment, so the answer is right even on the day the clocks change.
Example: a call at 09:00 on 20 March in New York is 13:00 in London (only four hours apart, because the US has already changed its clocks and the UK has not), but the same call on 10 April is 14:00 in London.
Questions
What happens with times that don’t exist because of daylight saving?
When clocks spring forward, one hour is skipped — in New York, 02:30 on the change day never happens. If you pick a time like that, the converter moves it forward by the skipped amount (to 03:30), the same rule most calendar apps use.
And times that happen twice?
When clocks fall back, one hour repeats. The converter uses the first of the two (still on daylight saving time). If you mean the second one, add an hour.
Can I share a converted time?
Yes. The address bar updates as you change the time and cities, so you can copy the link and send it — the other person sees the same moment in their own list.
Is my data sent anywhere?
No. The conversion happens entirely in your browser using its built-in time zone database.
