Synchronization Context

Operating on opposite sides of the clock, these cities have virtually no overlapping business hours. Expect a 24-hour turnaround for most communications.

Calgary Business Pulse

Culture Entrepreneurial, professional, and influenced by the energy and tech sectors.
Lunch Break 12:00 PM - 1:00 PM.
Pro Tip Best times for calls are 9:00 AM to 11:30 AM. Calgary is a practical, results-oriented city with a strong entrepreneurial spirit. Mountain Time is great for North American syncs. A professional but friendly and "no-nonsense" approach is the most effective here.

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.
