Best time to schedule a meeting
Standard 9–5 working hours do not overlap at all between EST and NZDT. Someone has to take an early or late call — or use asynchronous communication instead.

About EST
Eastern Standard Time (EST) is UTC−5. It is used in New York, Toronto, Miami and Atlanta in winter.
Eastern Standard Time is UTC−5 and applies in New York, Toronto, Miami and Atlanta only from November to March. For the other eight months those cities are on EDT, UTC−4. Americans routinely write "EST" year-round to mean "east coast time", so a date given as EST in July is usually meant as EDT and is an hour earlier than written — one of the most common scheduling errors there is. Note also that Panama and Jamaica are on UTC−5 all year and never switch.
About NZDT
New Zealand Daylight Time (NZDT) is UTC+13. It is used in New Zealand from late September to early April.
New Zealand Daylight Time is UTC+13, one of the few offsets past twelve hours and therefore a full calendar day ahead of most of the Americas. New Zealand's summer is the northern hemisphere's winter, so NZDT applies over Christmas — the opposite of every northern daylight-saving abbreviation, and a common mistake in end-of-year scheduling.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on EST switches to EDT (UTC−4) from March to November. So the 18-hour figure on this page is correct for the part of the year when both places are actually on these abbreviations, and changes by an hour outside it.
NZDT does not shift, so the whole change comes from one side. A recurring meeting fixed in NZDT will appear to move by an hour for everyone on the other side, twice a year, without anyone changing anything.
This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
Frequently asked questions
What time is 9:00 AM EST in NZDT?
9:00 AM EST is 3:00 AM NZDT (next day).
Is NZDT ahead of EST?
NZDT is 18 hours ahead of EST.
Which time zone does this use?
EST is UTC−5 and NZDT is UTC+13. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
