WhatTimeIsItIn...? is a free, fast world time tool covering more than 900 cities across all six inhabited continents. It was built for anyone who needs to know the local time anywhere on Earth at a glance — travellers, remote workers, international businesses, students, and the simply curious.
All times are calculated locally in your browser using the industry-standard IANA (Internet Assigned Numbers Authority) time zone database, the same database built into every major operating system and smartphone. This means times are always accurate, including during daylight saving time transitions.
WhatTimeIsItIn...? covers all major inhabited time zones, from UTC−12:00 (Baker Island) to UTC+14:00 (Kiribati), and is updated regularly to reflect new cities and time zone changes around the world.
UTC (Coordinated Universal Time) is the global standard for timekeeping. It does not change for daylight saving time and serves as the reference point from which all other time zones are calculated. For example, Dublin is UTC+0 in winter and UTC+1 in summer, while Tokyo is always UTC+9.
Daylight saving time is the practice of moving clocks forward by one hour during the warmer months to extend evening daylight. Not all countries observe DST — Japan, China, India, and most of Africa do not, while the USA, Europe, and Australia do, though on different schedules. WhatTimeIsItIn...? automatically accounts for DST.
There are 38 distinct UTC offsets in use worldwide, ranging from UTC−12 to UTC+14. Some countries like India (UTC+5:30) and Nepal (UTC+5:45) use half-hour or quarter-hour offsets rather than whole hours, which is why the world does not divide neatly into 24 zones.
France spans the most time zones of any country — 12 in total — due to its overseas territories spread across the globe. Russia has the most contiguous time zones on a single landmass, covering 11 zones from UTC+2 to UTC+12 across its vast territory.
The International Date Line (IDL) is an imaginary line running roughly along the 180° meridian in the Pacific Ocean. Crossing it eastward moves you one calendar day back, while crossing it westward moves you one day forward. This is why some Pacific island nations like Kiribati are among the first places on Earth to ring in the New Year.
Find both cities on WhatTimeIsItIn...? and compare their current times. The difference between them stays constant (outside DST transitions). For example, if London shows 12:00 and New York shows 07:00, there is a 5-hour difference — so a 15:00 London meeting would be 10:00 in New York. Always double-check around DST changeover weekends in March and November, when the gap can shift by an hour.
Many cities share a time zone because they fall within the same UTC offset band. For instance, Madrid, Paris, Berlin, Rome, and Amsterdam all use CET (Central European Time, UTC+1 in winter), so they always show the same time. Political and economic factors sometimes cause neighbouring countries to share a zone even when their geography might suggest otherwise.
GMT (Greenwich Mean Time) and UTC are often used interchangeably, but they are technically different. GMT is a time zone based on the mean solar time at the Royal Observatory in Greenwich, London. UTC is an atomic time standard kept by highly precise atomic clocks. In everyday use the difference is less than a second, but UTC is the modern scientific standard.
The Line Islands of Kiribati, including Kiritimati (Christmas Island), are the furthest ahead at UTC+14 — making them the first inhabited places to experience each new day. On the opposite end, the uninhabited Baker and Howland Islands sit at UTC−12, making them the last to experience each calendar day.
Yes. Despite spanning a geographical width that would naturally cover five time zones, all of China officially uses a single time zone: China Standard Time (CST), which is UTC+8. This was introduced in 1949 for national unity. In practice, western regions like Xinjiang informally use a second unofficial time that is two hours behind Beijing.
Times on WhatTimeIsItIn...? are calculated using your device's system clock combined with the IANA time zone database, which is maintained by a global team and updated whenever countries change their time zone rules. As long as your device clock is accurate (which it typically is, as smartphones and computers sync automatically), the times shown are correct to the second.
The IANA time zone database (also called the tz database or zoneinfo) is the world's most widely used and trusted source of time zone information. It is maintained by the Internet Assigned Numbers Authority and contains historical and current rules for every time zone on Earth, including all past and future daylight saving changes. It is used by Linux, macOS, iOS, Android, and most programming languages.
