What is the Time Zone Converter?
A time zone converter takes a date and time in one part of the world and tells you what time it is in another. This free tool covers 30 major zones — from Honolulu to Auckland — with correct daylight saving handling, so the answer is right whether you are scheduling next week or next March. Pick your date and time, choose the from and to zones, and the converted result appears instantly.
The built-in meeting planner solves the harder problem: finding a slot that works for everyone. Choose a date, your own zone, and four zones to compare, and the tool builds a table showing every hour from 9:00 to 18:00 in your time translated into each of the other zones. Scan a row to see one moment across all locations, or scan a column to find comfortable hours for one participant.
Daylight saving is where most converters quietly go wrong. Because this tool computes offsets with the browser's internationalisation database for your exact date, a meeting planned across the March or October clock changes converts correctly instead of landing an hour off. Offsets are shown next to each result so you can sanity-check them at a glance.
Remote teams, freelancers with international clients, and anyone booking calls across continents use this daily. There is no account to create and nothing to install — the conversion maths runs entirely in your browser, and the planner table is ready to screenshot or share in seconds.
For anything that truly matters — flight bookings, contract deadlines, live event go-times — state the time in UTC alongside local times and you eliminate an entire category of expensive mistakes. UTC never observes daylight saving, so 14:00 UTC means the same instant everywhere on Earth, and every participant can convert it confidently with this tool. When scheduling recurring meetings across zones, pick a fixed UTC slot rather than a fixed local time, and calendar apps will shift each occurrence correctly through clock changes. Be extra careful around the spring and autumn transitions: some local times occur twice or not at all on changeover days, so avoid scheduling critical events in those windows. For teams spread across many zones, publish a simple chart of core overlap hours — the meeting planner table here is a good starting point — and default to asynchronous updates outside those hours instead of dragging someone into a 3am call.
How to use it
- Pick a date and time — Enter the date and time of your event using the date-time picker.
- Choose the zones — Select the zone the time is currently in (From) and the zone you want to convert to (To) from 30 world zones.
- Press Convert — See the exact converted date and time with weekday and UTC offset shown for both zones.
- Open the meeting planner — Pick a planner date, your zone, and four comparison zones for the 9:00–18:00 overview table.
- Build and share the table — Press Build planner table, find overlapping work hours across the zones, and screenshot the table for your invite.
Common use cases
- Scheduling calls between teams in different countries
- Converting webinar and event times for an international audience
- Checking what time a flight departure is in your home zone
- Planning overlapping work hours for remote team standups
- Avoiding the classic daylight-saving one-hour-off scheduling mistake
Tips
- Always confirm the date too, not just the time — conversions can cross midnight.
- Recheck times near DST transitions; this tool handles them, but attendees' calendars may not.
- For recurring meetings, re-verify after each clock change in any participant's zone.
- Share the planner table screenshot in the invite so nobody has to convert mentally.
- When in doubt, state times in UTC alongside local times in important announcements.
Frequently asked questions
How do I convert time between time zones?
Enter your date and time, select the zone it is in and the zone you want, then press Convert. The tool shows the exact converted time with weekday and UTC offset, handling daylight saving automatically.
Does the converter handle daylight saving time?
Yes. Offsets are computed for your specific date using the browser's time zone database, so conversions across DST transitions in March and October come out correct.
What is the meeting planner for?
It builds a table of 9:00–18:00 in your zone translated into four other zones you choose, making it easy to spot overlapping work hours for international calls.
Which time zones are supported?
Thirty major zones across every continent, including UTC, London, Paris, Dubai, Karachi, Kolkata, Singapore, Tokyo, Sydney, New York, Chicago, Los Angeles and Honolulu.
