Coordination class
async-first pair
United States and Australia do not share standard 9-to-6 business hours today. Treat this as an async-first corridor and reserve synchronous calls for edge-hour handoffs.
Pair comparison
United States vs Australia
United States is 16.0 hours behind Australia. They have no overlap in standard 9-to-6 business hours — you'll need edge-hour meetings.
Country comparisons use one representative IANA zone per country, current public-holiday rows, and a same-day business-hour model. Multi-zone countries still need city-level checks before travel or payroll decisions.

Operational read on this pair
DST drift risk
3 sampled shifts / 12mo
Both sampled reference zones shift clocks. The offset gap can still move temporarily when the countries change on different weekends.
Holiday availability
16 vs 25 listed holidays
United States and Australia share 3 listed holiday dates in the selected year, so shared shutdown risk is visible before campaign or sprint planning.
Pair workflow examples
What fixed local work times become across the pair
The current offset is enough for today, but the examples below make the page useful for real recurring work: standups, reviews, and end-of-day handoffs anchored to either country. Recheck these around DST transition weeks when either sampled zone shifts.

Best live-use strategy
No shared 9-to-6 window appears today, so United States and Australia should use async-first workflows, rotating live calls, and written decision logs.
