World Clock (Time Zones, Local, Meeting Planner)
One glance shows what time it is for teammates, clients, or friends worldwide. Perfect for scheduling calls or coordinating launches.
See the current time across major cities and plan meetings easily.
An indispensable dashboard for distributed teams and global freelancers. Add cities from every continent, compare overlapping business hours visually, and immediately copy formatted local timestamps to prevent disastrous scheduling miscommunications or missed product launches.

- Steps and copy are checked against the current tool behavior.
- Browser limits, file-size constraints, or compatibility gaps are documented when relevant.
- Unless a page explicitly says otherwise, files and text stay in the browser during processing.
Coordinating the Distributed Workforce
In 2026, remote work is the baseline, but time zones remain an inescapable logistical nightmare. Whether you are managing an engineering sprint with developers in London, supporting a client in Tokyo, or deploying a server update from New York, guessing "their time" inevitably leads to missed meetings and burned bridges.
The Problem with Mental Math
It's easy to remember that London is 5 hours ahead of New York—until Daylight Saving Time kicks in. Because different countries switch their clocks on different weekends (and some countries have abandoned the switch entirely), mental math is highly dangerous. We built this clock using the browser's native Intl API, meaning the complex geopolitical offset rules are automatically calculated with zero margin for error.
Built for Schedulers
- The Overlap Window: By pinning multiple cities to your dashboard, you can visually scan the Day/Night indicators to find that elusive 2-hour window where everyone on the team is actually awake and on the clock.
- One-Click Conversion: Don't type "Let's meet at 9 AM my time, which I think is 2 PM your time." Use the tool to generate an exact, formatted timestamp and paste it directly into your Slack or Teams channel to enforce absolute clarity.
How to Convert a Meeting Time Across Time Zones by Hand
Every row on this page is a real IANA time zone, not a fixed offset, so the number shown next to each city is the offset that applies on the date you are viewing. That single detail explains most missed calls, because an offset memorised in March can be wrong in November.
Convert between two rows in three steps:
- Note the offset displayed for each city on the selected date.
- Subtract the smaller offset from the larger one to get the gap between them.
- Check the date beside the clock, because a gap wider than 12 hours usually pushes the result into the previous or the next calendar day.
The board opens with Los Angeles, New York, London, Berlin, Shanghai and Tokyo. Typing part of a name such as Adelaide or Kathmandu into the search field adds that zone from the browser's full IANA list, and any row can be removed. The date picker moves the whole board to a future date, the auto-update switch freezes the display for a stable screenshot, and each row has a copy button for the timestamp it is showing.
Worked example. A team in Adelaide holds a Wednesday standup at 10:00 and a colleague in Los Angeles wants to join. On 15 July 2026 Adelaide is on UTC+9:30 and Los Angeles is on UTC-7, a gap of 16 hours and 30 minutes, so 10:00 Wednesday in Adelaide is 17:30 Tuesday in Los Angeles. On 15 November 2026 the same standup lands at 15:30 Tuesday in Los Angeles, because Adelaide has moved to UTC+10:30 while Los Angeles sits on UTC-8, widening the gap to 18 hours and 30 minutes. The Adelaide wall clock never changed; only the winter time rules did.
Two offsets are worth remembering because they never move at all: India stays at UTC+5:30 and Nepal at UTC+5:45 all year. Fractional offsets are the part people round away by accident, and half an hour is exactly what turns a same-day delivery promise into a missed one.
If you are counting down to a call rather than converting it, the countdown timer handles the timer side, and the date calculator answers how many days sit between today and the meeting date. The guide to the world clock tool and time zone conversion goes further into how the board handles zones.
Key features
- Multi-city dashboard: Pin the locations you care about most and watch them update in real-time.

- Copy-ready timestamps: Grab formatted times (e.g., Wed 09:00 PT) to drop into emails, chats, or calendar invites.
Frequently asked questions
Does it handle daylight saving time?
Yes. Time zones use the browser’s Intl API, so offsets automatically adjust for DST.
Can I add any city?
Start typing a city or time zone name to search the built-in database, then pin it to your list.
Is the time accurate?
Yes. We synchronize with your device's system clock and apply precise timezone offsets. However, if your device's clock is wrong, the world clock will be too.
Does it work offline?
Yes. Once loaded, the clock continues to tick and update all cities using local JavaScript, even without an internet connection.
Do you store the cities I add?
The list exists only in your browser. Refresh the page to reset.
