What it does
This converter takes a time in one zone and shows it in major cities worldwide, so you do not have to do the arithmetic in your head.
It is built for the everyday problem of coordinating across countries: scheduling a call with a colleague abroad, catching a livestream at the right local moment, or working out when a deadline in another zone actually falls for you.
Everything runs in your browser using your system's time zone data, so nothing you enter is uploaded.
How daylight saving is handled
Daylight saving is the part people get wrong, and the tool handles it for you. Conversions use your device's time zone database, so the shifts are applied correctly for the exact date and city, not just a fixed offset.
Which cities are shown
It shows a selection of major cities across every continent, from Honolulu to Auckland, with UTC included as a neutral reference point that never changes with the seasons.
Why the exact date matters
Because offsets change with daylight saving, the same city can be an hour different depending on the date, which is why entering the exact day matters when the timing is tight.
Frequently asked questions
Does it handle daylight saving time?
Yes. Conversions use your device's time zone database, so daylight saving shifts are applied correctly for each date and city.
Which time zones are shown?
A selection of major cities across every continent, from Honolulu to Auckland, plus UTC as a reference.
Why might a city be an hour off what I expect?
Time zone offsets change with daylight saving. Pick the exact date you mean, because the same city can be +1 or +2 hours from UTC depending on the season.
What is UTC?
Coordinated Universal Time is the global reference that time zones are defined against. It does not observe daylight saving, so it is a stable anchor for comparing times.
Why do recurring meetings drift after a clock change?
Countries change to and from daylight saving on different dates, so for a week or two the usual offset between two cities shifts, moving a fixed local meeting by an hour for one side.
