How do you convert U.S. market hours to another time zone?

Take 9:30 a.m. and 4:00 p.m. Eastern and show those same moments in the zone you pick. In winter, London sees the regular session from 2:30 p.m. to 9:00 p.m. The calculator uses today's offset, so daylight saving time is already in the result.

Does the calculator include pre-market and after-hours?

Yes. It shows NYSE Arca's early session, 4:00 a.m. to 9:30 a.m. Eastern, the regular session, and the late session until 8:00 p.m. Eastern. Your broker may open a shorter window. On an early-close day the regular session ends at 1:00 p.m. Eastern. The table shows a normal day.

Is this investment advice?

No. The calculator is for general informational and educational purposes only. It is not a recommendation to buy, sell, or hold any security.
