The short answer: it depends which market you mean
There is no single global stock market opening time. The New York Stock Exchange, London Stock Exchange, Tokyo Stock Exchange, Toronto Stock Exchange, and Korea Exchange all follow their own local schedules. A market can also be closed for a national holiday even when another major exchange is open.
The safest way to answer “what time does the stock market open today?” is to check three things: the exchange, the exchange timezone, and whether today is a trading holiday. Global Exchange Clock combines those into one live status view so you can see whether a market is open now and when it opens next in your local time.
Common opening times for major stock markets
- NYSE and NASDAQ: 9:30 AM to 4:00 PM Eastern Time.
- London Stock Exchange: 8:00 AM to 4:30 PM London time.
- Toronto Stock Exchange: 9:30 AM to 4:00 PM Eastern Time.
- Tokyo Stock Exchange: 9:00 AM to 3:30 PM Japan time, with a lunch break.
- Korea Exchange: 9:00 AM to 3:30 PM Korea time.
These are regular trading hours, not a guarantee that the exchange is open today. Holidays, early closes, and local calendar rules can override normal hours.
Why “today” matters
Many trading-hour pages list a static schedule, but users usually need a live answer. “Open today” is different from “normally open on weekdays.” For example, the US market may be closed for Martin Luther King Jr. Day, Good Friday, Thanksgiving, or Christmas Day. The UK market follows its own bank holiday calendar. Asian exchanges may observe local holidays that do not affect Western markets.
This is why a reliable market-hours page should show both the regular session and today’s actual state: open, closed, lunch break, holiday, or opening soon.
How to check the next market open
- Choose the exchange or region you care about.
- Check whether the exchange is open today.
- Convert the exchange’s local time into your timezone.
- Look for the next open, close, lunch break, or holiday.
For live answers, start with the relevant market page: NYSE trading hours, NASDAQ trading hours, London Stock Exchange hours, TSX trading hours, or Tokyo Stock Exchange hours.
