When New York and Sydney can actually talk

On a standard 09:00–17:00 day there is no overlap at all between New York and Sydney. One side has to take the call outside their working hours — there is no arrangement of a normal working day that avoids it. Themeeting planner shows how much either side has to stretch, and who is affected least.

Calculated for Sunday, 13 September 2026. Because the gap changes during the year, this window moves with it — the planner recomputes it for any date you pick.

Questions

New York and Sydney, explained

What is the time difference between New York and Sydney?

There is no single answer, which is why most converters get this wrong for part of the year. Sydney is 14 hours ahead, 15 hours ahead, 16 hours ahead relative to New York at different points in the year. Right now it is 14 hours ahead. The table on this page gives the exact dates for each.

Why does the difference between New York and Sydney change?

New York moves between UTC-05:00 and UTC-04:00, while Sydney moves between UTC+10:00 and UTC+11:00. Because the two do not change on the same weekend, and in opposite hemispheres they change in opposite directions, there are short windows each year where the gap is different from the rest of it.

When is the difference between New York and Sydney unusual?

The shortest window runs from Sunday, 14 March 2027 to Friday, 2 April 2027 — 20 days during which Sydney is 15 hours ahead relative to New York 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.
