About this Time Zone Converter
This tool helps you compare time across cities, plan meetings for distributed teams, and share a single link that everyone can open to see the meeting time in their own time zone. Pick the cities, choose a meeting time, and the converter shows each city's local clock, UTC offset, and whether the slot falls inside standard business hours. The shareable link encodes everything in the URL, so recipients see the identical plan without having to type anything.
How time zones work
The world is divided into 24 nominal hourly offsets from Coordinated Universal Time
(UTC), but in practice the offsets are far from uniform. Many zones sit on the half
hour — India is UTC+5:30, Adelaide in South Australia is UTC+9:30 in winter — and a
few use quarter-hour offsets, the best known being Nepal at UTC+5:45. A smaller
number of regions, such as the Chatham Islands in New Zealand, use UTC+12:45.
Because this converter relies on the browser's native
ICU timezone database via
IANA names like Asia/Kolkata, all of these offsets are handled
automatically.
Daylight Saving Time (DST)
Many countries shift their clocks forward in spring and back in autumn, which means the offset between two cities can change by an hour twice a year. The conversion here always uses the offset that applies on the specific date you choose, so a meeting planned in July between London and New York uses summer offsets (UTC+1 and UTC-4), while the same meeting in January uses winter offsets (UTC+0 and UTC-5). Two edge cases deserve care: the missing hour during a spring-forward transition, and the repeated hour during a fall-back transition. The tool resolves both by referring to the IANA database's rules for the chosen zone.
Frequently Asked Questions
-
How do I schedule a meeting across time zones?
Put the city with the most awkward hours first — it becomes the reference. Add every other city, switch on the business-hours highlight, and use the suggested meeting window to find a slot that works for everyone.
-
Does this handle half-hour and quarter-hour offsets?
Yes — India (UTC+5:30), Adelaide (UTC+9:30 in winter), Nepal (UTC+5:45), and the Chatham Islands (UTC+12:45) are all handled correctly using the browser's native IANA time zone database.
-
Does the shareable link update automatically?
Yes — every change to cities, time, format, or view updates the URL. Copy the link and anyone who opens it sees the identical plan, converted to their own screen.
-
What happens during a Daylight Saving Time transition?
The tool always uses the offset that applies on your chosen date. For recurring meetings, re-check the plan around DST changes in March and October/November.
