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.
About MDT
Mountain Daylight Time (MDT) is UTC−6. It is used in Denver and Salt Lake City from March to November.
Mountain Daylight Time is UTC−6, the summer clock for Denver and Salt Lake City. During those months it coincides with Central Standard Time, which is a genuine source of confusion in a country that spans both: a meeting at "6pm MDT" and one at "6pm CST" are the same instant, but the second is not a time anyone is actually on in summer.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on MDT switches to MST (UTC−7) from November to March. So the 19-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 NZDT in MDT?
9:00 AM NZDT is 2:00 PM MDT (previous day).
Is MDT ahead of NZDT?
MDT is 19 hours behind NZDT.
Which time zone does this use?
NZDT is UTC+13 and MDT is UTC−6. 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.
