About the Time Zone Converter
This converter takes a wall-clock date and time in one zone and tells you the matching clock time in another. It reads the time you pick as being in the from zone, resolves it to a single real moment, then formats that moment in the to zone — all through the browser’s built-in Intl time-zone database, so there are no offset tables to fall out of date. Choose a date and time, set the two zones, and it also shows the same instant across a row of major world cities. The from zone defaults to your own.
Because it measures each zone’s real offset at that exact instant, daylight saving is handled for you: New York reads UTC−4 in summer and UTC−5 in winter automatically, and half-hour zones such as India (UTC+5:30) come out correctly. That makes it useful for scheduling a call across continents, checking when a stream starts, or working out what time an overseas deadline lands locally. See also the date difference calculator and the countdown timer.
Two things are worth knowing. It relies on your browser’s own time-zone data — every modern browser ships it and keeps it current — and the world-cities panel formats each time using your device’s locale. And because it converts one specific date and time rather than a fixed gap, pick the right date: the difference between two zones can change with the seasons.
Frequently asked questions
Does it handle daylight saving time?
Yes, automatically. It looks up each zone’s actual offset at the exact instant you enter, so a summer date and a winter date can convert differently — for example New York shifts between UTC−4 and UTC−5.
Why does the offset change depending on the date I pick?
Because many zones move their clocks for daylight saving, the gap between two zones is not fixed year-round. The converter works from a specific date and time, so choosing the correct date gives you the correct offset.
Do half-hour and 45-minute zones work?
Yes. It uses the browser’s Intl time-zone database rather than whole-hour assumptions, so zones like India at UTC+5:30 are converted accurately.
Where does the time-zone data come from?
From your own browser’s built-in Intl time-zone database. Every modern browser includes it and keeps it up to date, so there is nothing to download and no server lookup involved.
What does the “same moment around the world” panel show?
It shows the exact instant you converted, displayed in a set of major world cities at once, formatted using your device’s locale. It is handy for seeing how one moment lands everywhere at a glance.
