- Look at the Best times row at the bottom — green hours work for everyone.
- Hover any cell to see the matching UTC hour.
- Switch between 24h and 12h in the top right; your choice is remembered.
- Search by name (e.g. "India Standard Time"), city ("Kolkata", "New York") or abbreviation ("PST", "AEST").

A simple, free UTC and time zone converter
UTC Converter is a fast, free time zone converter you can use in any modern browser. The visual scale at the top of the page shows Coordinated Universal Time (UTC), Greenwich Mean Time (GMT) and your local time on three side-by-side rulers, so it's instantly clear what "3pm UTC" means where you are. Drag the indicator to slide a moment in time across all three zones at once.
The Meeting Scheduler underneath turns the same engine into a cross-time-zone meeting planner. Add up to five teammates, set each person's time zone, and the tool shows everyone's local hour for every UTC hour, colour-coded as working, acceptable or sleeping. The "Best Times" row highlights the hours that work for everyone — no spreadsheet required.
Conversions use the IANA time zone database
through your browser's built-in Intl.DateTimeFormat API,
so daylight-saving transitions and recent rule changes are handled
automatically. Searching the time zone box accepts cities
(e.g. "New Delhi", "São Paulo", "Sydney"), full names
(e.g. "Pacific Standard Time") and abbreviations (e.g. "PST", "AEST",
"IST").
Frequently asked questions
What is the difference between UTC and GMT?
UTC (Coordinated Universal Time) is the modern global time standard, kept accurate to within a fraction of a second using atomic clocks. GMT (Greenwich Mean Time) is a historical solar-based time zone tied to Greenwich, England. For most everyday purposes UTC and GMT show the same clock time, but UTC is the technically correct reference used in aviation, computing, and international standards.
How do I convert UTC to my local time?
Open the 3-Timezone Scale at the top of this page, search for your time zone (try a city, a country or an abbreviation like "EST"), and drag the indicator across the rulers. Your local hour appears alongside UTC and GMT in real time, with the correct daylight-saving offset applied automatically.
Can I schedule a meeting across multiple time zones?
Yes. Scroll to the Meeting Scheduler and use + Add user to add up to five people, each with their own name and time zone. Every row shows that person's local hour for every UTC hour, colour-coded for working hours, acceptable hours and sleeping hours. The Best Times row at the bottom highlights hours that work for everyone.
Is UTC Converter free to use?
Yes. UTC Converter is free for personal and professional use, with no sign-up, no subscription and no usage limit. The site is supported by a small number of unobtrusive ads — see our Privacy Policy for details.
Does UTC Converter handle daylight saving time?
Yes. Conversions use the IANA time zone database through your
browser's built-in Intl.DateTimeFormat API, so
daylight-saving transitions and recent legal changes to a
country's time zone rules are applied automatically.
Do I need to install anything?
No. UTC Converter runs entirely in your browser. Nothing is installed, and your time zone selections never leave your device.
