Time Zone Converter
Enter a date and time in one city and see exactly what it is in another. Daylight saving is applied automatically, so the answer is always correct.
Stop guessing across time zones
Anyone who has tried to set up a call between two countries knows the small dread of getting it wrong, joining an hour early or, worse, waking someone in the middle of the night. The cause is almost always the same: we remember a time difference from one part of the year and forget that it can change. Countries shift their clocks for daylight saving on different dates, and some never shift at all, so the gap between two cities is not a fixed number you can safely memorise. This converter sidesteps the whole problem by anchoring the time you enter to the real offset in force on that exact date, then re-expressing it in the second city with its own offset applied.
How to use it
Pick the date and time in the city where the moment is defined, say the hour a meeting is set in your office. Choose that city as the "from" location, and choose the other person's city as the "to" location. The result shows their local time, the full date there, which may roll over to the next day or back to the day before, and the two UTC offsets involved so you can see exactly how the conversion was made. It is the simple difference between a meeting that lands at a civilised hour for everyone and one that quietly excludes half the people you wanted in the room.
The logic underneath
Every conversion here routes through Coordinated Universal Time, the world's neutral reference. The tool takes your local time, works out the matching UTC instant using the source city's rules for that date, and then translates that single instant into the destination city using its rules. Because it relies on your browser's built-in time-zone data, it handles the awkward edges automatically, including the brief windows around daylight saving changeovers when clocks spring forward or fall back. For a broader view of many places at once, the world clock shows live local times side by side, and the articles section has a complete, plain-language guide to UTC, GMT and daylight saving if you would like to understand the machinery turning behind the scenes.
