Synchronization Context

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

Jakarta Business Pulse

Culture Collectivist and polite. Respect for elders and social harmony (Gotong Royong) is important.
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.

Sydney Business Pulse

Culture Relatively relaxed but professional. Early starts are common to maximize daylight.
Lunch Break 12:00 PM - 1:00 PM.
Pro Tip Due to the significant time difference with Europe and the US, early mornings (8:30 AM - 10:00 AM) are often dedicated to international syncs. For domestic calls, late mornings are best. Be mindful that many Australians start and end their day earlier than their Northern Hemisphere counterparts.
