View and compare the current time in multiple cities and time zones around the world. Add and remove clocks as needed. Great for remote teams, scheduling international calls, or just knowing what time it is somewhere else. All times update live every second.
The world spans 24 primary time zones, plus several with 30 or 45-minute offsets, and the International Date Line adds another layer of complexity. This world clock displays current time across multiple locations simultaneously, making it invaluable for international business, remote team coordination, and travel planning. Unlike single-conversion tools, seeing all times at once reveals patterns: when it's 9 AM in New York, it's 2 PM in London, 3 PM in Paris, 10 PM in Beijing, and 11 PM in Tokyo. The display updates in real time and accounts for Daylight Saving Time transitions, which occur on different dates worldwide.
There are 24 primary UTC-offset zones, but over 40 in practice due to 30-minute offsets (India: +5:30, Iran: +3:30), 45-minute offsets (Nepal: +5:45), and political decisions. Some large countries use fewer zones than their geography suggests (China uses only one).
China adopted a single timezone (UTC+8, Beijing Time) in 1949 for national unity, despite spanning 5 geographical time zones. This means sunrise in western China can be as late as 10 AM Beijing time. Some regions informally use their own 'local time.'
An imaginary line roughly along the 180° meridian where the date changes. Crossing westward, the date advances one day; crossing eastward, it goes back one day. The line zigzags to avoid splitting countries across two dates.
For US + Europe: 9-11 AM Eastern (2-4 PM London). For US + Asia: 8-9 AM Pacific (midnight-1 AM Tokyo next day) — no good overlap exists. For Europe + Asia: 9-10 AM London (5-6 PM Beijing). Consider rotating meeting times for fairness.
No — only about 70 countries observe DST, mostly in North America and Europe. Most of Africa, Asia, and South America do not. Countries near the equator have minimal daylight variation and see no benefit from DST.
