About this tool
See which major exchanges are open or closed, with a countdown to each change.
The Global Market Session Clock shows whether five major stock exchanges are inside their regular trading hours right now — NSE 09:15-15:30, London 08:00-16:30, New York 09:30-16:00, Tokyo 09:00-15:00 and Hong Kong 09:30-16:00, each in its own local time. It reads the current time in the exchange's IANA time zone, marks it Open only on a weekday between the session start and end, and lists the local weekday, clock time and session window side by side. It is for traders, analysts and anyone scheduling calls across markets who needs one screen instead of five world clocks.

Open the clock — there is no lookup box to fill, because NSE, London, New York, Tokyo and Hong Kong are already configured.
Press Get current result to read each exchange in its own IANA zone at request time.
Every row gives the exchange's local weekday and 24-hour time, Open or Closed, and its session window such as 9:15–15:30.
Each exchange is evaluated in its IANA zone (Asia/Kolkata, Europe/London, America/New_York, Asia/Tokyo, Asia/Hong_Kong), so daylight-saving shifts are handled without you adjusting anything.
A market is only reported Open on Monday to Friday local time, so a Saturday check does not show a session running because the clock happens to read 10:00.
Every row prints the exchange's own weekday and 24-hour local time alongside its session window, so you can see how far into or away from the session you are.
Five: NSE India 09:15-15:30 IST, London 08:00-16:30 UK time, New York 09:30-16:00 Eastern, Tokyo 09:00-15:00 JST and Hong Kong 09:30-16:00 HKT. These are regular continuous-session hours and exclude pre-open, auction and after-hours phases.
No. The status is computed from weekday plus local clock time only, so an exchange closed for a national holiday will still show as Open during its usual window. Check the exchange's own holiday calendar before acting on the status.
Because each market is modelled as one continuous window from open to close, and intraday breaks are not encoded — Tokyo and Hong Kong both pause around the middle of the day. Treat the reading as 'inside regular session hours' rather than 'trading is live this second'.
The current time is converted to the exchange's local hour and minute, and the market counts as Open when the local day is Monday to Friday and the local time is at or after the open and strictly before the close. At the closing minute itself the row flips to Closed.
