Los Angeles to Seoul Time

Los Angeles (United States) is a global financial and tech hub, with key industries in technology, finance, healthcare, and entertainment. Seoul (South Korea) is a technology-driven economy known for rapid innovation, known for semiconductors, automotive, shipbuilding, and K-content. With a 17-hour time difference, professionals frequently schedule cross-border calls between these two cities for international trade, remote team collaboration, and client meetings.

Scheduling Meetings Between Los Angeles and Seoul

With Seoul 17 hours ahead of Los Angeles, there is minimal overlap in standard business hours. Most teams alternate meeting times to share the burden of early-morning or late-evening calls fairly. US business hours typically run 9 AM–5 PM, with a culture that values punctuality and efficiency. South Korean work culture is fast-paced with typical hours of 9 AM–6 PM, though recent reforms have reduced maximum weekly hours. Consider recording meetings for those who can't attend live, and use shared documents for async collaboration.

Daylight Saving Time Considerations

Los Angeles observes Daylight Saving Time (PST/PDT), but Seoul does not — it stays on KST year-round. This means the time difference between Los Angeles and Seoul changes by 1 hour when Los Angeles switches clocks. During United States's summer, the gap is 16–18 hours instead of the standard 17 hours. Mark DST transition dates on your calendar to avoid missed meetings.

PST (PST/PDT) stands for the timezone used in Los Angeles, United States (UTC-8). KST (KST) is the timezone used in Seoul, South Korea (UTC+9). Los Angeles is 17 hours behind Seoul.

To convert PST to KST, add 17 hours to PST time. For example, PST 9:00 AM = KST 2:00 AM.
