Synchronization Context

A 4 hours 30 minutes gap allows for a manageable shared window, typically in the morning or late afternoon. It requires some scheduling but supports daily synchronization.

Singapore Business Pulse

Culture Efficiency-driven and highly professional. A major global hub for finance and tech.
Lunch Break 12:30 PM - 1:30 PM.
Pro Tip Aim for 10:00 AM to 11:30 AM for maximum focus. Late afternoon (4:00 PM - 5:30 PM) is the ideal time to synchronize if you are calling from Europe or the Middle East. Singaporeans are highly punctual and expect the same from their international partners.

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.
