Seoul & Adelaide — Business & Scheduling Guide
Seoul is a global tech and cultural powerhouse, known for Samsung, LG, K-pop, e-sports, semiconductors, and 5G leadership. Adelaide (Australia) is a stable, resource-rich economy in the Asia-Pacific region, known for mining, agriculture, finance, and tourism. With a 0.5-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 Seoul and Adelaide

South Korean work culture is fast-paced with typical hours of 9 AM–6 PM, though recent reforms have reduced maximum weekly hours. Australian work culture values work-life balance, with typical hours of 9 AM–5 PM and flexible arrangements common. Most teams find that late morning to early afternoon offers the widest window for collaboration.
Daylight Saving Time Considerations

This typically happens in spring and fall, and the exact dates vary by country. If you have recurring cross-timezone meetings, recalculate the schedule after each DST transition.
