- Pro Tip Ideal window is 9:30 AM to 11:30 AM. As a major logistics and aviation hub, business is fast-paced and international. Punctuality and rapid response times ("Pali-pali") are expected. Follow formal hierarchical protocols strictly in all professional communications.
Jakarta Business Pulse

- Lunch Break 12:00 PM - 1:00 PM (11:30 AM - 1:30 PM on Fridays).
- Pro Tip Best call window is 9:30 AM to 11:30 AM. On Fridays, avoid calling between 11:30 AM and 1:30 PM due to congregational prayers. Indonesians value "face" and social harmony; avoid being overly blunt or confrontational. Relationship building is a critical first step for any business deal.
