What is the Timezone Converter tool?
This timezone converter takes a date and time in one city or timezone and shows you exactly what it is in another — no mental math, no counting on your fingers, no guessing whether a place is ahead or behind. Pick your source date and time, choose the two timezones from a list covering major cities across the Americas, Europe, the Middle East and Asia-Pacific, and the converted result updates instantly using your browser's own timezone database, so it correctly accounts for daylight saving time wherever it applies.
It is built for the everyday problem of coordinating across time differences: scheduling a call between New York and Dubai, checking what time a Riyadh meeting lands in London, or figuring out whether a Tokyo release goes live before or after your Cairo workday ends. The result card shows the converted date and time in full, plus the abbreviated zone name and the exact hour difference between the two zones at that moment, so you know at a glance who is ahead and by how much.
Because it runs entirely in your browser using the standard time-zone data built into every modern device, there is nothing to install, no account, and no data ever leaves your device. Swap the two zones with one tap to flip the conversion around, or jump straight to 'now' to see the live time difference between any two places right this second.
How to use the Timezone Converter
- Set the date and time you want to convert, or tap 'now' to use the current moment.
- Choose the 'From' timezone — the city or zone the date and time belongs to.
- Choose the 'To' timezone — the city or zone you want to convert into.
- Read the converted date and time, plus the exact hour difference between the two zones.
- Tap the swap button any time to flip the from/to zones and convert the other direction.
Frequently asked questions
Does this timezone converter account for daylight saving time?
Yes. It uses your browser's built-in timezone database, which tracks daylight saving rules for every zone, so the converted time is correct for the specific date you pick — not just a fixed offset that ignores clock changes.
Which timezones are covered?
A curated list of roughly 30 major zones spanning the Americas, Europe, the Middle East and Africa, and Asia-Pacific — including Cairo, Riyadh, Dubai, London, New York, Tokyo and more — enough to cover almost any real-world scheduling question.
Can I convert a time in the past or future, not just right now?
Yes. Pick any date and time — past or future — and the conversion still applies the correct daylight-saving rules for that specific date, which matters most around the spring and autumn clock-change windows.
How accurate is the hour difference shown?
It is calculated at the exact converted instant using each zone's real offset from UTC at that moment, so it reflects the true difference on the date you picked, even for zones that shift by a non-whole-hour amount.
Is this timezone converter free and does it work offline?
Yes — completely free, with no sign-up. Once the page has loaded it runs entirely on your device using the timezone data your browser already has, so nothing is sent to a server.
