What is the time difference between London and San Franciso?

Answer 1

London is usually eight hours ahead of San Francisco.

From the second Sunday of March at 10:00 UTC (2 AM PST; 10:00 GMT) until the last Sunday of March at 01:00 UTC (Sat. at 6 PM PDT; Sun. at 01:00 GMT), London is seven hours ahead of San Francisco.

From the last Sunday of March at 01:00 UTC until the last Sunday of October at 01:00 UTC (Sat. at 6 PM PDT; Sun. at 02:00 BST), London is eight hours ahead of San Francisco.

From the last Sunday of October at 01:00 UTC until the first Sunday of November at 09:00 UTC (2 AM PDT; 09:00 GMT), London is seven hours ahead of San Francisco.

From the first Sunday of November at 09:00 UTC until the second Sunday of March at 10:00 UTC, London is eight hours ahead of San Francisco.

04:00 PST (in San Francisco Nov-Mar) =
05:00 PDT (in San Francisco Mar-Nov) =
12:00 GMT (in London Oct-Mar) =
13:00 BST (in London Mar-Oct)

Answer 2

During most of the year, when it's 9 AM in San Francisco, it's 5 PM in London.

9 AM Pacific Standard Time = 5 PM Greenwich Mean Time

9 AM Pacific Daylight Saving Time = 5 PM British Summer Time

However, the U.S. and Europe do not start and end Daylight Saving Time/ Summer Time on the same weekends, so between the 2nd and last Sundays of March and during the week of Oct. 31st, when it's 9 AM PDT in San Francisco, it's 4 PM GMT in London.
