Time Zone Converter
Time Zone Converter
Time Zone Map
Convert any date and time between two places, with daylight saving handled for you.
How the conversion actually works
Enter the date and time in the first city, pick a second city, and the answer appears immediately. The conversion uses whichever rules were actually in force for both zones on that specific date, which is why converting the same clock time in July and in December can genuinely land an hour apart.
The three mistakes that cause almost every conversion error
Almost every conversion error traces back to one of three habits, and each is easy to avoid once you know to look for it.
- Treating the gap between two cities as fixed. London and New York usually sit five hours apart, but for roughly two weeks in March and one in November — while only one of the two has changed its clocks — that gap is four. Convert the real date rather than relying on the usual figure.
- Misreading a 24-hour time as 12-hour. A schedule that says 19:00 means seven in the evening — reading it as simply “7” puts a meeting out by exactly twelve hours.
- Forgetting that the calendar date itself can shift. Nine in the morning on Monday in Los Angeles is already two in the morning on Tuesday in Karachi. This converter always shows the resulting date alongside the time for exactly that reason.
When a different tool fits better
For anything involving more than two people, the best meeting time finder is the better tool — it shades every participant’s working hours at once, so a slot that suits everyone is something you can see rather than something you have to calculate by hand. To see exactly how two specific cities track against each other hour by hour, the time difference calculator is the more direct option.
Questions people ask
Does the converter handle daylight saving on its own?
Yes, for both places involved, and specifically for whatever date you enter — including dates in past or future years, not just today.
Can I convert directly to or from UTC?
Yes. Type UTC or GMT into either field and it appears alongside the regular city options.
Which time zone does the converter start on?
Your own, detected automatically from your browser. Change the first field if you’d rather convert between two entirely different places.
Why did my converted result land on a different calendar date?
Once two places are far enough apart, part of every single day genuinely falls on a different calendar date for one of them — the converter shows that resulting date deliberately, for exactly this reason.
Can I convert a time that’s already in the past?
Yes. Historic conversions apply whichever rules were actually in force on that specific date, so a meeting recorded last winter converts correctly even if the local offset has since changed.
What should I actually write in a cross-timezone invitation?
Your own local time plus your zone name, or a plain UTC time. ’14:00 UTC’ is unambiguous absolutely everywhere; ‘2pm’ on its own isn’t.
Why can a flight’s arrival time look earlier than its departure time?
Because arrival times are printed in local time at the destination. Crossing several zones heading west can genuinely land you before you left, by the clock — though obviously not in real elapsed time.
