World Clock

Compare time zones and pick a meeting time in your browser.

Clock format

The clocks appear here once the page has loaded.

Click or tap the strip to pick an hour from that half hour (the left half of a cell is :00, the right half :30); drag or Shift+click for a range, in half-hour steps. On the strip, Left and Right move the selection by 30 minutes, Shift+Left and Shift+Right change its end, Home goes to now and Escape clears it. Start and End take 15-minute steps. Working hours are 9:00–18:00; night is shaded and marked with a moon, and a row whose time falls outside them is tagged Night, Early or Late.

Runs in your browser. Nothing is uploaded.

The clock shows the current time in up to 10 places. Type a city, a time zone (“Asia/Tokyo”, “Pacific Time”, “UTC”) or an abbreviation (“CET”) into “Add city or time zone”. Each row shows the name, an abbreviation badge, the time and the offset from the first row, your home. The house button makes a row home, arrows reorder rows and × removes one.

To convert a time between zones or pick a meeting time, use the 24-hour strips. Every strip covers the same day in the home zone, and each column is the same moment in every row. Night (22:00–7:00) is shaded and marked with a moon, early and late hours (7–9, 18–22) are tinted, and working hours are 9:00–18:00. Click a strip to pick an hour from the clicked half hour, drag or Shift+click for a range in half-hour steps, or type Start and End in 15-minute steps. A row whose time falls outside working hours is tagged Night, Early or Late. Tabs cover yesterday to five days ahead; the calendar button picks any date.

A selection can be downloaded as an .ics file, opened in Google Calendar, Outlook.com or Gmail, or copied as text or a link. Nothing is sent by this site.

Example

Home is Vilnius, the second row is Denver, the date is Wednesday, 21 October 2026, and the selection is 15:30–18:00 in Vilnius.

  • Vilnius: 3:30 pm – 6:00 pm (EEST, UTC+3)
  • Denver: 6:30 am – 9:00 am (MDT, UTC−6), offset −9, tagged Night (6:30 am is before 7:00).

Limitations

  • The list has about 3,190 cities: population of at least 200,000, plus every capital. Smaller places can be added by time zone or zone name.
  • Zone rules come from your browser’s built-in data, so a recent rule change may be missing in an older browser.
  • About 90 abbreviations are known; other zones show a label such as “GMT+5”.
  • Up to 10 places. The selection stays within one day of the home zone; the strip moves in half hours, Start and End in 15 minutes.

City names, countries and time zones come from GeoNames (geonames.org), licensed under CC BY 4.0.

FAQ

How do I see what time it is in another city?

Type the city into “Add city or time zone” and pick it from the list. Its row shows the current time and the difference from home, such as “+5:30” or “−9”.

How do daylight saving changes affect the times shown?

Each row follows its own zone’s rules, so offsets change during the year. A row notes “Daylight saving time” while it is in force and “Clocks change today” on the day of a switch. On such a day the home strip has 23 or 25 hours.

Why are some zones :30 or :45 away?

Some countries set standard time at a half or quarter hour from UTC. India uses UTC+5:30, Nepal UTC+5:45 and the Chatham Islands (New Zealand) UTC+12:45.

Why are abbreviations like IST or CST ambiguous?

One abbreviation can name several zones. IST can mean Indian, Irish or Israel Standard Time; CST can mean Central Standard Time (UTC−6) or China Standard Time (UTC+8). The search lists every meaning with its region.

The address holds the places, date, time range and 12h or 24h setting, for example ?p=vilnius,America/Denver&d=2026-10-21&t=15:30-18:00. It never holds the event title, and nothing is stored on a server. “Save as my default” keeps your places in this browser only; “Forget” removes them, and a link with its own places takes priority.
