Time Zone Converter
Convert a time from one zone to another to find the matching local hour.
Choose two time zones and a time, and this converter shows what that moment reads as on each side's clock. It is the quick answer to “if it's 9am here, what time is it there?” — the everyday problem behind scheduling a call, a webinar, or a hand-off with someone in another region. The conversion runs in your browser using its built-in time-zone database.
Daylight saving is the part people get wrong
The gap between two zones is not always fixed, because regions shift their clocks for daylight saving time on different dates — and some do not shift at all. That means the difference between, say, London and New York can be four or five hours depending on the week. Converting from a named zone rather than a raw “+5” offset is what keeps you right, because the zone knows whether summer time is in effect. Around the changeover weekends, always double-check.
A practical way to pick a meeting time
To find a slot that suits both sides, set one zone to your own and step the time through your working day, watching the other zone's hour. You are looking for the overlap where both clocks fall inside sensible hours — a mid-morning start for you might already be early evening elsewhere. Nailing this down before you send the invite avoids the classic mistake of booking a colleague for the middle of their night.
Frequently Asked Questions
Does it account for daylight saving time?
Yes. Because it converts between named zones using the browser's time-zone data, it applies whether summer time is currently in effect — which is why the gap between two places can change by an hour across the year.
Why is the difference between two cities not what I expected?
Most likely one of them has just started or ended daylight saving. The offset between zones is not constant; it shifts on each region's changeover dates, and some regions never change at all.
How do I use it to schedule a call?
Set one zone to yours, then move the time across your working hours and watch the other zone. Book the slot where both clocks sit within reasonable hours.
Is anything sent to a server?
No. The conversion uses your browser's built-in time-zone information and runs entirely on your device.
