WORLD CLOCK · LOCAL DATE · IANA TIME ZONES
World time and date in cities around the world
Find the current local time and date for a city anywhere in the world. Search by city or country, or browse a curated list of major cities by continent.
The clock updates every second and shows the numeric date, a written date, the current UTC offset, and the time-zone name. English dates use U.S. month/day/year order.
Location search uses a bundled offline catalog. Daylight-saving and other time-zone rules come from your browser’s IANA database, not a server or external API.

World clock and date lookup by city
Compare the local calendar date and wall-clock time in locations across every continent. Each result includes its IANA time-zone identifier and the UTC offset currently in effect, so locations that observe daylight saving can show a different offset during the year.
What the city time tool shows
- live local time with seconds and the numeric date in U.S. month/day/year format;
- the same date written with the weekday and month name;
- the place’s country, IANA time-zone identifier, localized time-zone name, and current UTC offset;
- automatic daylight-saving transitions calculated with the browser’s built-in Intl API;
- offline city and place search from a local GeoNames catalog, plus a short list of major cities.
The city catalog is based on GeoNames cities5000: places with more than 5,000 residents or administrative-capital status. It is not a record for every settlement, and many different cities share a time zone. Rules are supplied by the browser’s installed IANA TZDB and may lag recent legal changes.

Frequently asked questions
What is an IANA time zone?
It is a regional identifier such as Europe/Paris or America/New_York. The browser combines it with its time-zone rules to calculate local time for a selected instant.
Does the tool account for daylight saving time?
Yes. The browser’s built-in Intl.DateTimeFormat applies daylight-saving transitions when they exist for the selected zone and date. The tool does not implement its own time-zone rules.
Why can cities in one country show different times?
Many countries span several time zones. Each catalog place has an IANA zone, so its local time depends on the selected city rather than the country alone.
What does the UTC offset mean?
It is the difference between local time and UTC at the selected instant. The offset can change at a daylight-saving transition; the current time-zone name is shown as well.
How accurate is the clock to the second?
The display refreshes once per second and uses your device clock. Accuracy depends on that clock, browser performance, and background-tab throttling; it is not a precision time-synchronization source.
Why might a browser show different time-zone rules?
Rules come from the version of the IANA TZDB bundled with the browser or operating system. After a recent rule change, browser updates may arrive at different times.
Can I rely on the display for historical dates?
The tool displays the current date, and past rules are limited to the IANA data available to the browser. Historical names, offsets, and transitions may be incomplete or revised.
Why do different cities sometimes show the same time?
Some cities genuinely share a time zone and have the same local time at a given moment. Locations are not assigned artificial unique zones to make them look different.
Why can’t I find a particular city?
The local catalog is based on GeoNames cities5000, which includes places with more than 5,000 residents and administrative capitals. Small settlements and some local name variants may be missing.
Which time zone is used for an ambiguous place name?
Results show the country and IANA zone next to the city name. If a city or metro area has no single generally accepted zone, the catalog record represents the selected geographic place.
Does search work offline?
Yes, after the page and city-catalog file have loaded. To reopen the page offline, the browser or local web server still needs access to those files.
Does the site request my location?
No. The tool does not use geolocation; you choose a city manually. Its location-selection analytics event does not include the city name or time zone.
How is the date formatted in Russian and English?
Russian uses DD.MM.YYYY plus a written date. English (US) uses MM/DD/YYYY and a written date in U.S. order.
