World time — answered
- What time is it right now in major world cities?
- Right now it is 04:21 AM in New York, 09:21 AM in London, 05:21 PM in Tokyo, and 07:21 PM in Sydney. All times update live on this page.
- What is UTC time?
- UTC (Coordinated Universal Time) is the global time standard. All world timezones are defined as offsets from UTC — for example, New York is UTC−5 in winter, London is UTC+0, Tokyo is UTC+9. UTC never observes daylight saving time.
- How many timezones are there in the world?
- There are 24 standard timezones, but with half-hour and quarter-hour offsets (used by India, Iran, Nepal, and others) the total is around 38 distinct UTC offsets in use worldwide.
- What is the time difference between New York and London?
- New York is currently 5 hours behind London. This gap is 5 hours in winter (EST vs GMT) and 4–6 hours during the brief spring and autumn transition periods when the two cities switch to daylight saving time on different dates.
- What is the time difference between London and Tokyo?
- London is currently 8 hours behind Tokyo. Tokyo does not observe daylight saving time, so this gap shifts by 1 hour when London moves between GMT (UTC+0) and BST (UTC+1) in summer.
- What is the time difference between New York and Tokyo?
- New York is currently 13 hours behind Tokyo.
- Which countries observe daylight saving time?
- Most of Europe, the United States, Canada, and Australia observe daylight saving time, shifting clocks forward by one hour in summer. Countries near the equator (including Japan, China, India, and most of Africa and Southeast Asia) do not observe DST. Russia abolished DST in 2014.
- What is the IANA timezone database?
- The IANA Time Zone Database (also called the Olson database) is the authoritative global list of timezone identifiers used by operating systems, programming languages, and APIs. Examples: America/New_York, Europe/London, Asia/Tokyo. This site uses IANA identifiers for all 990 cities.
