# World clock: today's date around the world

The current date and time in 44 cities from Honolulu to Kiritimati, and which of them are already on tomorrow or still on yesterday compared with you.

## The short answer

Clocks around the world run from UTC−12 to UTC+14, a spread of 26 hours, so every calendar date is in use somewhere for about 50 hours. From 10:00 to 12:00 UTC each day three dates are in use at once: tomorrow in Kiribati's Line Islands, today in most of the world, and yesterday on Baker and Howland Islands. Your browser carries its own copy of the IANA tz rules, and every clock here is worked out from it.

## Reading the board

Each card shows the local time and date in that city right now, worked out in your browser from your device clock and each city's time-zone rules. A card's date line turns blue when that city is already a day ahead of you, and amber when it is still a day behind. For about two hours every day — from 10:00 to 12:00 UTC — three different dates are in use around the world at once.

## Time zones and the date

A time zone is a region that shares one clock time, usually defined as an offset from Coordinated Universal Time (UTC). Offsets range from UTC−12, used only by two uninhabited US islands, to UTC+14 in Kiribati's Line Islands. Many zones also shift by an hour for daylight saving time, and they do so on different dates: the United States and Canada change on the second Sunday of March and the first Sunday of November, the European Union on the last Sundays of March and October, and the southern hemisphere the other way round. For a few weeks each spring and autumn, the gap between New York and London is four hours instead of five.

Some countries span several zones. The contiguous United States has four, Russia eleven, Australia three in winter and five in summer. China, which is as wide as the contiguous US, uses one time — UTC+8 — for the whole country, so in the far west the sun can be highest in the sky at 3 pm.

## Planning across time zones

When you schedule a call, the date matters as much as the hour: a Monday-morning meeting in Sydney is still Sunday afternoon in California. Before you send an invitation, check both the time and the date on the board above. Public holidays also start and end at local midnight, so a team in Tokyo can be on holiday while you are still on the previous working day — the [holidays page](https://whathappen.today/holidays/) shows today's status in 28 countries.

## Worked example: a 23:30 UTC call

A video call set for 23:30 UTC on Friday 9 October 2026 lands on 2 different days:

| City | Local date and time |
| --- | --- |
| Los Angeles | Friday 9 October 2026, 16:30 |
| New York | Friday 9 October 2026, 19:30 |
| London | Saturday 10 October 2026, 00:30 |
| Tokyo | Saturday 10 October 2026, 08:30 |
| Sydney | Saturday 10 October 2026, 10:30 |

The invitation has to say Friday for Los Angeles and New York, but Saturday for London, Tokyo and Sydney.

## Limits

- Times follow your device clock; if it is off, every card is off by the same amount.
- Governments change time-zone rules at short notice; an outdated browser can apply an old rule until it is updated.
- Each card shows one representative city; places in the same country can use another zone.

## Questions and answers

Which place sees a new date first?

Kiritimati (Christmas Island) in Kiribati, at UTC+14. Its clocks reach midnight 14 hours before UTC does, and 25 hours before the last inhabited places to see the same date, American Samoa and Niue at UTC−11.

Where does the date change?

At the International Date Line, which runs roughly along the 180° meridian through the Pacific but bends around island groups so that each country keeps one date. Crossing it westbound you add a day; eastbound you repeat one.

Why are some offsets not whole hours?

Countries choose their own standard time. India uses UTC+5:30, Nepal UTC+5:45, central Australia UTC+9:30, Newfoundland UTC−3:30, and the Chatham Islands of New Zealand UTC+12:45 (+13:45 in summer).

Do the times change for daylight saving automatically?

Yes. The clocks follow your browser's own copy of the IANA time-zone database, so daylight-saving changes in Europe, North America, Chile, Australia and New Zealand are applied on the right dates. If your browser is very old, its rules may be out of date.

Why don't I see my city?

The board shows a fixed set of large cities across all time zones. Use “Look up a city” to see any of more than 300 cities and capitals; for sunrise and sunset times there, use the [sunrise and sunset page](https://whathappen.today/sunrise-sunset/).

Times come from your device clock and the time-zone database in your browser. If your device clock is wrong, every time here will be wrong by the same amount.
