Synchronization Context
Syncing between Seoul and Tehran is challenging due to the 5 hours 30 minutes offset. Teams should prioritize asynchronous communication or specific 'handover' windows.
Seoul Business Pulse
- Culture Extremely hardworking and hierarchical. "Pali-pali" (hurry-hurry) culture drives rapid growth.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip The ideal window is 9:30 AM to 11:30 AM. South Koreans value speed ("Pali-pali") and expect rapid responses. Avoid the 12-1 PM lunch hour strictly. Ensure you follow hierarchical protocols if senior leaders are present, and never arrive (digitally or in-person) late for a call.
Tehran Business Pulse
- Culture Relationship-heavy and formal. Respect for hierarchy is paramount.
- Lunch Break 1:00 PM - 2:00 PM.
- Pro Tip The work week is Saturday to Wednesday. Thursday is often a half-day. Call between 9:00 AM and 12:00 PM. Iranian business culture is very formal and involves "Taarof" (a complex system of etiquette); be patient, polite, and avoid rushing into business without proper greetings.
