Market Session Clocks

the US market is closed. Regular NYSE and Nasdaq hours are 9:30 AM to 4:00 PM Eastern Time, Monday to Friday, excluding published market holidays. The exchanges close early, at 1:00 PM ET, on a small number of published half days.

Green means the exchange is trading and the bar underneath shows how much of the session has run. Amber means it is halted for its midday break. Blue means extended-hours trading only. Red is reserved for a published holiday or half day — an ordinary overnight or weekend close is left plain, because closed is the normal state most of the week and colouring all of it red would waste the warning.

Yes. Hover any clock and choose “Pin to front”. Pinned exchanges move to the front of the grid and stay there on your next visit. The choice is also written into the page address, so you can bookmark your own arrangement or send it to someone else and it will open the same way.

Click any clock and it opens in its own window at full screen size, ready to drag onto a spare display. That window carries the exchange name, the live time, the countdown to the next open or close, and a switch between the digital readout and the 24-hour session dial. Press F for true full screen.

The Tokyo Stock Exchange genuinely stops trading between 11:30 and 12:30 local time, and Hong Kong and Shanghai take similar midday breaks. Most market-hours sites ignore this and show those venues as open right through the break.

No. The United States and the United Kingdom change their clocks on different dates — the US springs forward about three weeks before the UK does, and the UK falls back about a week before the US. During those windows London and New York sit four hours apart instead of five, and the overlap window moves. The whole-market-day view marks the overlap live, reading every offset from the IANA timezone database rather than assuming a fixed gap.

A date only appears on this site once it has been checked against the exchange’s own published calendar. Where that has not been done yet the clock knows the weekday sessions but not the local public holidays, and says so rather than quietly guessing. New York and Sydney are verified today.

Session times, holiday closures and half-day dates are published calendar facts taken from each exchange’s own website. This site carries no prices, quotes, index levels or volume — that is proprietary exchange data and is deliberately out of scope.
