Seoul & Manaus — Business & Scheduling Guide
Seoul is a global tech and cultural powerhouse, known for Samsung, LG, K-pop, e-sports, semiconductors, and 5G leadership. Manaus (Brazil) is the largest economy in South America, known for agriculture, mining, manufacturing, and fintech. With a 13-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 Manaus
With Manaus 13 hours behind Seoul, 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. South Korean work culture is fast-paced with typical hours of 9 AM–6 PM, though recent reforms have reduced maximum weekly hours. Brazilian business culture values personal relationships, with typical hours of 9 AM–6 PM. Consider recording meetings for those who can't attend live, and use shared documents for async collaboration.
Daylight Saving Time Considerations
Neither Seoul nor Manaus observes Daylight Saving Time — Seoul stays on KST and Manaus stays on AMT year-round. This makes scheduling between these two cities simpler, as the 13-hour time difference remains constant throughout the year with no DST surprises.
Collaboration Tools & Workflow
With a 13-hour time difference, Seoul and Manaus teams operate in a near "follow-the-sun" model. When one team logs off, the other picks up — enabling near-24-hour productivity on shared projects. The key challenge is handoff quality: teams should document decisions in shared tools (Notion, Confluence, Linear), record video updates with Loom, and write thorough pull request descriptions. Weekly all-hands meetings require someone to take an early morning or late evening call, so the best practice is to rotate this burden fairly between Seoul and Manaus.
Remote Work Between Seoul & Manaus
Seoul, Samsung, and Manaus, a key city in Brazil, represent a common corridor for distributed teams navigating a 13-hour time difference. Remote workers and freelancers operating between these cities should plan their day around the overlap window — typically the late morning for one city and early morning or late afternoon for the other. Using a world clock widget, setting Slack status with local time, and blocking "no-meeting" deep work hours outside the overlap are essential practices for productive cross-timezone remote collaboration between Seoul and Manaus.
