Daylight saving time × standard time
Because Brasília has no daylight saving time, the LSE time on your clock changes when the other side changes its clocks. Here are both tables, calculated with real time zone rules:
| Phase | Local time | Brasília |
|---|---|---|
| Pre-trading | 07:00–07:50 BST | 03:00–03:50 |
| Opening auction | 07:50–08:00 BST | 03:50–04:00 |
| Regular session | 08:00–16:30 BST | 04:00–12:30 |
| Closing auction | 16:30–16:35 BST | 12:30–12:35 |
| Post-close | 16:40–17:15 BST | 12:40–13:15 |
| Phase | Local time | Brasília |
|---|---|---|
| Pre-trading | 07:00–07:50 GMT | 04:00–04:50 |
| Opening auction | 07:50–08:00 GMT | 04:50–05:00 |
| Regular session | 08:00–16:30 GMT | 05:00–13:30 |

The next clock change in the United Kingdom is on Sunday, October 25, 2026: daylight saving time ends and standard time returns (the clocks go back one hour). From Monday, October 26, 2026, in Brasília time the open moves from 04:00 to 05:00 and the close moves from 12:30 to 13:30.
US and European clocks do not change on the same day: the next US change is on November 1, 2026 and the next European change on October 25, 2026. For 7 days London and New York are 4 hours apart instead of the usual 5.
Overlap in Brasília time
Window when both regular sessions are open at the same time, calculated for Wednesday, October 7, 2026:
- LSE × NYSE: 10:30–12:30 (with the UK on winter time (GMT, UTC+0): 11:30–13:30)
Who trades and when
The London Stock Exchange is the main exchange of the United Kingdom and one of the most international in the world, with stocks such as Shell, HSBC and AstraZeneca and the FTSE 100 index. London uses GMT in winter and BST (UTC+1) in summer, so Brasília time falls several hours behind it.
The LSE trading day (SETS system) starts with pre-trading from 7:00 and the opening auction (7:50–8:00), in London time. Continuous trading runs until 16:30, followed by the closing auction (16:30–16:35) and a post-close phase. On the eve of some holidays the LSE closes early, which this page does not take into account.
London is the bridge between Asia and New York: the end of the Tokyo session almost meets the London open, and London's afternoon overlaps New York's morning, when a large share of currency trading volume is concentrated.
Hours source and holidays
The hours follow the general trading schedule published by the exchange (see the London Stock Exchange website (londonstockexchange.com)). The exchange can change its schedule, so check the exchange website before trading. Market holidays and early-close days are not considered on this page: check the LSE trading calendar.
