- Handling a -13h gap: Sydney and Brazil have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Brazil is 8:00 PM in Sydney.
- Keeping family and friends in sync: knowing that 8:00 PM in Sydney is 7:00 AM in Brazil makes it easy to avoid calling at 3 AM.
