Global Market Hours: How to Track Trading Sessions
Understand global stock exchange sessions, local market clocks, overlaps and the difference between market hours and 24/7 crypto trading.
The concept in plain English
CATCO's market hours clock calculates regular trading sessions from the current time in each exchange's time zone. It is a schedule-based clock, not a live exchange feed, and does not adjust for holidays or early closes. Crypto is shown as a continuous market.

Exchange schedules follow the venue's time zone, not a fixed UTC offset. US and European daylight-saving transitions happen on different dates, temporarily changing the overlap between sessions. Use the exchange-local time as the anchor. A regular-session indicator cannot account for trading halts, every holiday or every instrument. Before a time-sensitive order, check the venue calendar and your broker's available session.
A regular New York session
An ordinary NYSE trading day with no holiday or early close, at 10:00 a.m. New York time.
The regular 9:30 a.m. to 4:00 p.m. session is 6 hours 30 minutes long. At 10:00 a.m., 6 hours remain.
The regular-hours clock shows an open session and a six-hour countdown to close.
This is a schedule calculation, not a live exchange-status feed. An exchange notice takes precedence.
Calculation method
Each venue is evaluated in its official IANA time zone against its regular weekday schedule. The next state change is calculated from the upcoming local open, break, reopen or close.

Questions about Global Market Hours Clock
Is the stock market open on weekends?
Major stock exchanges normally close on weekends, while cryptocurrency venues commonly operate around the clock. Holiday calendars can also close weekday sessions.
Why do exchange times move in my local time?
Markets follow their own local time zones. Daylight-saving changes occur on different dates, so the apparent offset can change during the year.
Are extended hours included?
The primary status focuses on regular sessions. Check your broker and exchange for pre-market, post-market and instrument-specific access.
