FAQ

Does this page always say the NYSE is open from 9:30 a.m. to 4:00 p.m. ET today?
No. Those are regular full-session hours. In a browser, the page first checks the New York date against its embedded weekend, holiday and half-day table.
What does the page show on an embedded holiday or weekend?
It reports closed today instead of claiming regular hours. On a listed half-day it reports a 1:00 p.m. ET early close.
What happens after the embedded calendar coverage expires?
The page declines to state today's session and asks the reader to verify the official exchange calendar.
