Runs entirely in your browser using your device clock and the built-in time-zone
database — no servers, no sign-up, works offline. Daylight Saving is applied automatically for the
exact date you pick.
Convert any time between any two (or three) world time zones instantly and accurately. This free
converter supports every IANA time zone your browser knows, automatically applies Daylight Saving
Time (DST) rules for any date — past or future — and shows the live current time in each zone, a
full-day half-hour conversion chart, and the best overlapping working hours for scheduling a meeting.
Your own time zone is detected automatically. Pick your zones, choose a date and time, and see the
converted time both ways at once — editing either side updates the other. Add a third zone for group
scheduling, and share any conversion with a single link. Half-hour and 45-minute zones such as India
(GMT+5:30), Nepal (GMT+5:45) and the Chatham Islands (GMT+12:45) convert correctly because every offset
is read live from your browser's built-in time-zone database.
Frequently asked questions
How does this time zone converter handle Daylight Saving Time (DST)?#
Automatically and correctly. Every offset is measured live from your browser’s built-in IANA time zone database at the exact date and instant you pick — not from a static table. That means spring-forward and fall-back transitions, and even half-hour and 45-minute zones like India (GMT+5:30) and Nepal (GMT+5:45), are all handled accurately for past, present, and future dates.
Can I convert a time for a specific future date, not just right now?#
Yes. Set any date and time in the date and time pickers. The converter applies the Daylight Saving rules in effect for that specific date in each zone, so scheduling a call three months out is accurate even if a country changes its clocks in between.
How do I share a converted time with someone in another country?#
Click “Copy link”. The URL encodes the from zone, to zone, optional third zone, and the exact date and time, so whoever opens it sees the identical conversion — the easiest way to confirm a meeting time across zones without back-and-forth.
Yes. Click “Add a third zone” to add another time zone. The clocks, the hour-by-hour chart, and the meeting-overlap highlighting all update to include it — useful for scheduling across three regions.
Set your working hours (default 9:00 AM to 5:00 PM) and the conversion chart shades each half-hour slot by how many of your selected zones are within working hours at that moment. The “Best meeting times” summary lists the slots where everyone overlaps, so you can pick a call time that is reasonable for all parties.
Do I need to install anything or create an account?#
No. The tool runs entirely in your browser, works offline after the first load, needs no sign-up, and sends none of your data to a server — all conversions happen locally on your device.
Why does the converted time sometimes show a different day?#
When two zones are far apart, the converted time can land on the previous or next calendar day. Each result and chart row shows a “Previous day” or “Next day” badge so the date difference is always clear.
