Los Angeles to London time difference
London is eight hours ahead of Los Angeles when Los Angeles is on PST and London is on GMT. A 9:00 AM start in Los Angeles corresponds to 5:00 PM in London.
Los Angeles can switch to PDT and London can switch to BST. Because the United States and United Kingdom change clocks on different dates, the gap can briefly be seven or nine hours around the transitions; the selected date determines the result.
