What time does the US stock market open in the UK?

The October 2026 change: one week earlier in the UK

The UK returns to GMT on Sunday 25 October. New York stays on daylight saving time until Sunday 1 November. During the intervening trading week, London is four hours ahead of New York instead of five. The US opening time itself stays at 9:30 a.m.

Sources and date conversions checked on 15 October 2026. The timetable below covers 2026; check the current exchange calendar and any announcements before using it for a trading day.

Which opening time does this guide mean?

This guide covers the regular US stock session: 9:30 a.m.–4 p.m. Eastern Time on normal trading days. Both the NYSE core session and the Nasdaq Stock Market use that reference window. Other instruments, venues and broker services can have different schedules.

Use “New York time” or the America/New_York time zone when converting. “ET” follows the local clock through winter and summer; treating “EST” as a year-round fixed offset can give you the wrong answer.

2026 regular-session timetable in UK time

The conversions use America/New_York and Europe/London and were checked against the official clock-change dates. For Stockilm teaching dates, use the member schedule.

Why is the open sometimes at 1:30 p.m.?

In 2026 the US starts daylight saving time on 8 March, while the UK changes on 29 March. The trading days between those Sundays therefore have the earlier UK opening time. In autumn the UK changes first, on 25 October, and the US follows on 1 November.

During most of the year, both locations are either on their respective winter clocks or their respective summer clocks, leaving a five-hour difference. During the March and October gaps above, the difference is four hours. A repeating reminder fixed at 2:30 p.m. UK time will miss that distinction.

Holidays and shorter sessions still matter

Check the exchange calendar before converting a date. The NYSE and Nasdaq 2026 calendars include these remaining year-end exceptions.

UK bank holidays and US exchange holidays follow different calendars. Check the US equity-market schedule for the date, then convert the session. Also check current announcements for unexpected closures or stock-specific halts.

Pre-market, after-hours and broker access are separate

A broker may display prices or permit orders outside the regular session. Nasdaq publishes pre-market and after-hours windows and notes that broker access can differ. Seeing activity before 9:30 a.m. New York time does not mean the regular opening time has changed.

For access outside the regular session, check your broker’s current hours for the specific instrument and order type.

A practical way to plan your UK week

• First choose the actual date. Check whether the US stock exchange has a full session, a short session or a holiday.
• Convert 9:30 a.m. in America/New_York to Europe/London. For the October gap, compare Friday 23 October at 2:30 p.m. with Monday 26 October at 1:30 p.m.; Monday 2 November is back at 2:30 p.m.
• If you use a calendar, anchor a market-open reminder to New York time and check its UK display around both clock changes. Keep your own preparation time separate from the exchange opening time.
• Plan when you will review your decisions as well as when you will be available. A journal can help you record what you planned, what happened and what you need to revisit.

How this relates to Stockilm’s live sessions

Stockilm uses 9:30 a.m. New York time as the reference for its scheduled market-open sessions with Yaseen. Use the UK conversion for the session date, and check member announcements for the actual teaching schedule. Confirm session duration, holiday arrangements and attendance expectations with the team.

The programme also includes Sunday Q&A, which has its own schedule, and recordings are available in Discord. Read the programme details to assess how the teaching format fits your routine.
