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

About EDT
Eastern Daylight Time (EDT) is UTC−4. It is used in New York, Toronto, Miami and Atlanta from March to November.
Eastern Daylight Time is UTC−4, the summer clock for New York, Toronto, Miami and Atlanta, running from the second Sunday in March to the first Sunday in November. Those dates are US law and do not match Europe's, which changes on the last Sundays of March and October — so for two weeks in March and one in late October the gap between New York and London is an hour different from its usual five.
About NZST
New Zealand Standard Time (NZST) is UTC+12. It is used in Auckland and Wellington in the southern winter.
New Zealand Standard Time is UTC+12, the furthest ahead of the commonly used abbreviations, moving to NZDT at UTC+13 from late September to early April. New Zealand is where the date changes first for most of the world's working population, which is why release schedules and financial rollovers are often expressed relative to it. Chatham Islands time, at UTC+12:45, is one of only three quarter-hour offsets in use anywhere.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on EDT switches to EST (UTC−5) from November to March. So the 16-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.
NZST does not shift, so the whole change comes from one side. A recurring meeting fixed in NZST 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 EDT in NZST?
9:00 AM EDT is 1:00 AM NZST (next day).
Is NZST ahead of EDT?
NZST is 16 hours ahead of EDT.
Which time zone does this use?
EDT is UTC−4 and NZST is UTC+12. 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.
