Tip: Times update live. Switch to Specific time to convert a chosen date and time across every zone.
Show the current time across multiple time zones at once, or switch to specific-time mode: pick a date and time in a source zone and see that exact moment in every other zone. It works as a live world clock and as a meeting planner for scheduling across regions. Add or remove cities freely; everything updates in your browser with no account or location permission.
This is a live world clock for comparing times across cities. Pick zones from the full IANA timezone database, which your browser exposes directly (around 400 entries, from Africa/Abidjan to Pacific/Wallis), and each appears as a card showing the current time in 24-hour format, updating every second, plus the full date with the weekday. Showing the date matters: when it is Friday evening in San Francisco it is already Saturday in Tokyo, and a clock without the date hides exactly the mistake that double-books people.
The search field matches city and region names and shows each zone's current UTC offset, such as GMT+05:00, so picking between similarly named zones is unambiguous. Daylight saving time needs no thought at all: times are computed by the browser's Intl engine, which applies the correct offset for today's date in each zone, including regions that skip DST entirely and ones with half-hour offsets like Asia/Kolkata.
Your selection is saved on the device, so the cities you care about (the default set is UTC, New York, London, and Tokyo) are already ticking the next time you open the page. Add as many zones as you need and remove any with one click; nothing requires an account, a location permission, or a network call.
- 1
Search for a zone
Type a city or region into the search box. Matching IANA zones appear in a dropdown with their current UTC offset.
- 2
Add it to the board
Click a result to add a card showing live 24-hour time and the full date with weekday, ticking every second.
- 3
Curate your set
Remove zones with the x button on each card. Your selection is saved locally and restored next time you open the page.
Scheduling across offices
Confirm that a 4 PM London call lands at 8 AM in San Francisco and 9 PM in Karachi before sending the invite.
Release coordination
Check what a 9 AM Eastern launch means for users in Tokyo, where it is already the next calendar day.
Remote family and friends
Keep a card for each relative's city so you never call at 3 AM their time by accident.
Markets and trading
Watch the current time in New York, London, and Hong Kong side by side as live ticking clocks.
Does it handle daylight saving time?
Yes, automatically. Each clock is computed by the browser's Intl engine using the IANA database, which applies the correct offset for the current date in every zone, including half-hour and 45-minute offsets like Asia/Kathmandu.
How many timezones can I add?
As many as you want from the full list your browser supports, around 400 IANA zones. The search dropdown shows up to 100 results at a time; keep typing to narrow the list.
Why does each card show the date as well as the time?
Because zone differences cross day boundaries. A Thursday evening meeting in Los Angeles is Friday morning in Sydney, and seeing the weekday on every card prevents off-by-one-day scheduling mistakes.
Does the tool know my location or send anything anywhere?
No location permission is requested and no network request is made. All clocks are computed locally from your system clock, and your saved city list is stored only on your own device.
Can I check a time other than right now?
The tool is a live clock showing current times. For a future event, read the UTC offsets shown next to each zone in the search results and apply the difference, keeping upcoming DST changes in mind.
