When Auckland and Perth can actually talk

That is comfortable: there is room for a recurring call without either side moving their day.
Calculated for Monday, 14 September 2026. Because the gap changes during the year, this window moves with it — the planner recomputes it for any date you pick.
Questions
Auckland and Perth, explained
What is the time difference between Auckland and Perth?
There is no single answer, which is why most converters get this wrong for part of the year. Perth is 5 hours behind, 4 hours behind relative to Auckland at different points in the year. Right now it is 4 hours behind. The table on this page gives the exact dates for each.
Why does the difference between Auckland and Perth change?
Auckland moves between UTC+12:00 and UTC+13:00, while Perth stays on UTC+08:00 all year. A gap only stays fixed when both ends are fixed. Here one end moves, so the difference moves with it even though nothing changed at the other end.
When is the difference between Auckland and Perth unusual?
The shortest window runs from Sunday, 4 April 2027 to Saturday, 25 September 2027 — 175 days during which Perth is 4 hours behind relative to Auckland rather than the usual amount. Short windows like this are where recurring meetings break, because nobody thinks to check.
Does this account for daylight saving automatically?
Yes. Offsets come from your device's own copy of the IANA time zone database through the browser's Intl API, so they reflect whatever rules are current rather than a table bundled here that could go stale. Pick any date in the converter and it resolves that date's rules, not today's.
