World Clock โ€“ Current Time in 40+ Countries

Keeping track of time across multiple time zones is one of the most common challenges in a globalized work environment. Whether you're scheduling a meeting with a colleague in Tokyo, checking if your client in New York is online, or planning a call with a team across three continents โ€” knowing the current local time in different countries is essential. Our World Clock displays the live current time in over 40 countries and major cities around the world.

Unlike static time zone tables, our World Clock updates every second, showing you the exact current time for each location. Times are calculated based on the official UTC offset for each region, with common daylight saving adjustments noted where applicable. You can also add any city from our list of 100+ supported locations using the search bar, and drag cards to rearrange them in your preferred order.

Time Zones Explained

A time zone is a region of the world that observes a uniform standard time for legal, commercial, and social purposes. Time zones are expressed as offsets from Coordinated Universal Time (UTC) โ€” the primary time standard by which the world regulates clocks. For example, New York is UTC-5 in winter (Eastern Standard Time) and UTC-4 in summer (Eastern Daylight Time). London is UTC+0 in winter and UTC+1 during British Summer Time.

Most time zones are offset from UTC by a whole number of hours, but some regions use half-hour or even quarter-hour offsets. India Standard Time (IST) is UTC+5:30 โ€” a 30-minute offset chosen to place the Indian subcontinent's midday closer to solar noon across its wide east-west span. Nepal Standard Time (NPT) is UTC+5:45, a 45-minute offset, making it one of the few quarter-hour time zones in the world. Iran uses UTC+3:30. These unusual offsets reflect political and geographic compromises rather than pure astronomical considerations.

Daylight Saving Time (DST) adds another layer of complexity. During DST, clocks are moved forward by one hour in spring and back in autumn, usually to extend evening daylight. Not all countries observe DST โ€” most of Africa, Asia, and countries near the equator do not, since seasonal day length variation is minimal there. The United States, Canada, most of Europe, and parts of South America and Oceania do observe DST, though the exact dates of transition differ by country.

Why Is Scheduling Across Time Zones Difficult?

Remote and distributed teams face real coordination challenges because of time zone differences. A few practical tips:

  • Use UTC as a common reference โ€” When setting meeting times with international participants, always state the time in UTC alongside local times to avoid confusion, especially around DST transitions.
  • Identify overlap windows โ€” Find the hours when all participants' working hours overlap. A team with members in San Francisco (UTC-8), London (UTC+0), and Singapore (UTC+8) has almost no natural overlap during standard business hours.
  • Rotate inconvenient times fairly โ€” For recurring meetings where no convenient time exists for everyone, rotate the inconvenient early morning or late evening slot among team members.
  • State DST transitions clearly โ€” When daylight saving time changes in one country but not another, standing meeting times can shift by an hour unexpectedly. Use a world clock tool to verify times around DST transitions in March/April and October/November.
  • Use the Convert mode โ€” Our World Clock's Convert mode lets you enter a specific date and time in one timezone and see the equivalent time in all your tracked cities simultaneously.

Countries and Time Zones Covered

Our World Clock covers 40+ major regions across all continents, including major cities in North America, South America, Europe, Africa, the Middle East, Central Asia, South Asia, Southeast Asia, East Asia, and Oceania.

Frequently Asked Questions

  • UTC stands for Coordinated Universal Time. It is the primary time standard by which the world regulates clocks and is the successor to Greenwich Mean Time (GMT). UTC is not adjusted for daylight saving time, making it a stable reference point for global time coordination. All other time zones are defined as positive or negative offsets from UTC โ€” for example, Japan Standard Time is UTC+9, and Eastern Standard Time (US) is UTC-5.
  • No. Daylight Saving Time is observed by approximately 70 countries, primarily in Europe, North America, and parts of South America and Oceania. Most countries in Africa, Asia, and near the equator do not use DST because the variation in daylight hours throughout the year is small enough that the adjustment is not considered beneficial. Notable non-DST countries include China, Japan, India, and most of the Middle East. Even within countries that observe DST, some regions may be exempt โ€” for example, the state of Arizona in the US does not observe DST (with the exception of the Navajo Nation).
  • India Standard Time (IST) is UTC+5:30, a half-hour offset from the nearest whole-hour time zones. This offset was chosen in 1947 as a political compromise to use a single time zone for the entire country despite India's considerable east-west geographical span. A half-hour offset places solar noon closer to 12:00 PM across more of the country than either UTC+5 or UTC+6 would. Nepal goes even further with a 45-minute offset (UTC+5:45) to distinguish itself from neighboring India and maintain a slightly more accurate solar alignment for its longitude.
  • The easiest approach is to use the Convert mode on this World Clock. Switch to "Convert Time," enter the date and time of your proposed meeting in your local timezone, and you'll immediately see what that time corresponds to in all your added cities. This lets you quickly check whether the proposed time falls within reasonable working hours for everyone involved. As a general rule, UTC 14:00โ€“17:00 (10 AM New York / 3 PM London / 10 PM Singapore) is one of the most widely usable windows for global teams spanning the Americas, Europe, and Asia.
