Riyadh to Seoul Time

Riyadh (Saudi Arabia) is the largest economy in the Middle East, with key industries in oil & gas, construction, finance, and tourism under Vision 2030. Seoul (South Korea) is a technology-driven economy known for rapid innovation, known for semiconductors, automotive, shipbuilding, and K-content. With a 6-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 Riyadh and Seoul

The 6-hour difference between Riyadh and Seoul requires careful scheduling. The best overlap window is typically 2–4 hours when both cities are within working hours. Saudi business hours typically run 9 AM–5 PM Sunday–Thursday, with business often conducted over meals. South Korean work culture is fast-paced with typical hours of 9 AM–6 PM, though recent reforms have reduced maximum weekly hours. Teams often designate specific "overlap hours" for real-time collaboration and use asynchronous communication (Slack, email, recorded video) for the rest of the day.

Daylight Saving Time Considerations

Neither Riyadh nor Seoul observes Daylight Saving Time — Riyadh stays on AST and Seoul stays on KST year-round. This makes scheduling between these two cities simpler, as the 6-hour time difference remains constant throughout the year with no DST surprises.

AST (AST) stands for the timezone used in Riyadh, Saudi Arabia (UTC+3). KST (KST) is the timezone used in Seoul, South Korea (UTC+9). Riyadh is 6 hours behind Seoul.

To convert AST to KST, add 6 hours to AST time. For example, AST 9:00 AM = KST 3:00 PM.
