World Clock
| City | Time | Day | vs you |
|---|
Six cities, one screen, ticking to the second: New York, Los Angeles, London, Dubai, Tokyo and Sydney - each running its own timezone rules with daylight saving handled automatically, because the clock reads your browser's own timezone database rather than a fixed offset. The "vs you" column is the meeting-planner column: how many hours each city sits from your clock, right now.
Bottom line: the useful column is the offset, not the time - a three-hour difference means the morning call works and the evening one doesn't, and the sign tells you who has to stay up. When the numbers confuse you, the daylight saving table explains the two Sundays a year that shift half the world.
The honest part: the six cities are the classic business spread; the clock does not take custom cities (yet). The times are your device's timezone database interpreted through the browser - as accurate as the device clock you keep.
How to use
- Read the row: city, live time to the second, the day and date it currently is there (the date can be a day ahead or behind yours), and the offset from you.
- Use the vs-you column to plan calls: differences under 6 hours share a working day; over 8, someone is taking the call at home.
- Bookmark for the meeting-planning loop - the offsets update themselves when either side changes the clocks.
Frequently asked questions
What time is it in New York right now?
The New York row ticks live to the second - no refresh needed. It reads America/New_York time, which is Eastern Time: five hours behind London in winter, four in summer, and it moves on the American daylight-saving schedule, which no longer matches Europe's.
Why do the time differences change during the year?
Because the US and Europe change their clocks on different dates - America springs forward in March, Europe in March too but on a different Sunday, and the southern hemisphere runs the opposite season entirely. For a few weeks each spring and autumn, the New York-London gap is 4 hours instead of 5. The "vs you" column re-computes every second, so it is always the live truth.
Can a city be a different date than mine?
Yes - Tokyo and Sydney sit ahead of the Americas by up to a full day: when it is Sunday evening in New York, it is already Monday morning in Tokyo. The Day column shows each city's own date, which is why it exists: meetings scheduled "Monday" need to agree whose Monday.
How accurate is this clock?
It is your device's clock, interpreted through the browser's timezone database - the same IANA data every scheduling system uses, so the timezone rules and daylight shifts are as current as your browser. The seconds tick live; if your device clock is right, the six cities are right.
