What UTC offset does Sydney use?

Sydney uses Australian Eastern Standard Time (AEST, UTC+10) from the first Sunday in April through the first Sunday in October, and Australian Eastern Daylight Time (AEDT, UTC+11) during the rest of the year. Because Sydney is in the southern hemisphere, its summer (and DST) is during the northern hemisphere winter.

What are typical business hours in Sydney?

Standard business hours in Sydney run 9 AM to 5:30 PM AEST/AEDT, Monday through Friday. The culture is generally less intense than New York or Tokyo; leaving on time is common. Lunch is typically 12:30 to 1:30 PM. Cafe culture is strong, and morning coffee before 9 AM is a near-universal ritual.

Why is scheduling with Sydney in the Americas so difficult?

Sydney is 15–16 hours ahead of New York (depending on DST) and 18–19 hours ahead of Los Angeles. There is effectively no overlap within standard business hours. The only practical option is early morning Sydney (which is the previous afternoon in the Americas) or late evening Americas (which is morning Sydney). Teams typically rotate the inconvenient slot.
