Pacific Time (PT) · PST (UTC−8) in winter · PDT (UTC−7) during Daylight Saving Time
Silicon Valley (Apple, Google, Meta, Netflix, Tesla, OpenAI) operates on Pacific Time. This means the entire global tech industry effectively follows PT: product launches, earnings calls, and keynotes are timed for 10 AM PT — which is 1 PM ET, 6 PM GMT, and 2:30 AM IST (next day).
California's $3.6 trillion GDP makes it the world's 5th largest economy — ahead of India and the UK. If California were a country, its Pacific timezone would be the most economically powerful timezone on Earth.
Hollywood also sets global entertainment schedules. Award shows (Oscars, Emmys) air at 5 PM PT, which means European audiences watch at 2-3 AM. Streaming services now release content at 12 AM PT — making Pacific Time the “zero hour” of global entertainment.
