Los Angeles and the US West Coast use Pacific Time — Pacific Standard Time (PST, UTC−8) in winter and Pacific Daylight Time (PDT, UTC−7) in summer. The transition follows the same US schedule: forward in March, back in November. Silicon Valley operates in this timezone, making PT a reference point for the tech industry.
