PST to GMT converter

PST to GMT quick reference

PST or PDT, GMT or BST? Daylight saving explained

PST (UTC−8) is the winter name and PDT (UTC−7) the summer name. People usually write “PST” all year and mean local Pacific time (Los Angeles, San Francisco, Seattle), so MeetETA reads it that way and handles daylight saving for you.

GMT (UTC+0) is UK winter time; from late March to late October the UK is on BST (UTC+1). People who say “GMT” for a London meeting usually mean UK time, so this page uses London time. If you mean GMT as a fixed UTC+0 all year, it is the same as UTC (and that is how the type-a-time box reads the word “GMT”; type “London” for UK time).

Right now Los Angeles is on PDT, UTC−7 and London is on BST, UTC+1 (the clocks at the top of the page always show the live values).

How the gap changes during the year

London is 8 hours ahead of Los Angeles for most of the year. For a few weeks it is 7 h, because the two sides change their clocks on different dates.
