TOOLConvert time across the world, correctly
Scheduling a call across countries? Enter a time and its zone, pick the target zone, and this converter gives you the exact local time there — with daylight saving handled automatically. It uses your browser's built-in time-zone data, so it stays accurate through the year and nothing is uploaded.
Why convert by zone, not offset
A fixed offset like "GMT+1" is wrong half the year because daylight saving shifts the clock. Converting by city or zone for a specific date uses the correct offset automatically, avoiding those one-hour mistakes that ruin meeting times.
Working out how long a call runs? Use the time duration calculator. Counting down to an event? Try the countdown timer.
A worked example
You have a call at 3:00 PM in New York and need the time in London. Pick the source zone and time, choose London as the target, and the converter shows 8:00 PM — accounting for the current five-hour difference. Because it uses named zones rather than a fixed number, it also gets the awkward weeks right: the US and UK change their clocks on different dates, so for a short window the gap is four hours, not five, and the tool reflects that automatically.
Scheduling across time zones
Remote teams, international clients and family abroad all run into the same trap: an offset you memorised quietly breaks when daylight saving shifts on one side. A few habits help — confirm the other person's city rather than an abbreviation, share meeting times with the zone spelled out, and double-check anything scheduled near the end of March or October when clocks change. To measure how long a call or gap lasts once times are aligned, use the time duration calculator.
Frequently asked questions
How does the time zone converter work?
You enter a time and its source zone, and the tool converts it to the target zone using your browser's built-in time-zone database, which includes daylight saving rules. Nothing is uploaded.
Does it handle daylight saving time?
Yes. It uses the standard IANA time-zone data built into modern browsers, so daylight saving shifts are applied automatically for the date you choose.
Why convert by city rather than offset?
A fixed offset like GMT+1 ignores daylight saving, which changes during the year. Converting by city or zone uses the correct offset for the exact date, avoiding one-hour mistakes.
