Time difference between Buenos Aires and Sydney
Sydney is 13 hours ahead of Buenos Aires
Buenos Aires, Argentina is UTC−3 · Sydney, Australia is UTC+10 — on standard time
The gap is not the same all year
Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Buenos Aires does not change its clocks and Sydney goes forward on the first Sunday in October and back on the first Sunday in April.
| Buenos Aires / Sydney clocks | Difference | How long |
|---|---|---|
| standard / standard | 13 hours ahead | about 26 weeks |
| standard / summer | 14 hours ahead | about 26 weeks |
Buenos Aires stays put all year while Sydney moves, so the gap changes twice a year from Sydney's side alone. A recurring meeting set in Buenos Aires's calendar will drift by an hour without anyone touching it.
When they can both be at their desks
Nine-to-five in Buenos Aires and nine-to-five in Sydney do not overlap at all. With 13 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
