See the time right now in as many cities as you like, side by side, updating every second. Add the cities you care about, and share the list with a link.

Everything you enter is processed in your browser and is never sent to a server.

How to use

  1. Your own city and a set of major cities are shown to start. Type a city or time zone in Add a city and press Add, or press Enter.
  2. Press the × on a card to remove that city.
  3. Each card shows the time, the date relative to today, the weekday, the UTC offset and whether the zone is on daylight saving time.
  4. Press Copy a link to this set of cities to share the exact set of cities with someone else.

Examples

New York, London, Tokyo, Seoul added
→ Four live clocks, each with its own date and offset
When it is morning in New York it can already be tomorrow evening in Seoul.
A city removed with ×
→ The card disappears and the link updates
The shared link always matches the cities on screen.
Reset to the default cities
→ Your own time zone plus a set of major cities, worldwide
A quick way back to a useful starting set.

How it works

Each card reads the current time in its time zone using the time zone data built into your browser (the IANA database), through the date-fns and @date-fns/tz libraries, and redraws every second. The offset from UTC, whether the zone is on daylight saving time, and the date relative to your own are all worked out from that same data, so they follow the real rules of each zone, including the ones that change their clocks on different dates from each other.

The set of cities is kept in the page’s own address, not on a server, so a shared link opens to the same set without any account or storage.

Frequently asked questions

How is my own time zone chosen?
From your device's own settings, the same way your computer or phone already knows what time it is. It is only read, never sent anywhere.
Why does a city show the day before or after?
Time zones are hours apart, and the date line means the calendar date can differ even for a small time difference, such as between Tokyo and Honolulu. Each card says Yesterday, Today or Tomorrow relative to your own date.
What does DST mean?
Daylight saving time: the zone has moved its clocks forward for part of the year. Not every country uses it, and the dates it starts and ends differ by country, which this page follows from your browser's own time zone data.
Can I share this exact list of cities with someone?
Yes. Copy a link puts the cities in the page's address, so opening that link shows the same set.
Is anything sent to a server?
No. The clocks are worked out in your browser from its own time zone data.
