Time difference between Denver and Auckland

Auckland is 18 hours ahead of Denver

Denver, the United States is UTC−7 · Auckland, New Zealand is UTC+12 — on standard time

The gap is not the same all year

Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Denver goes forward on the second Sunday in March and back on the first Sunday in November and Auckland goes forward on the last Sunday in September and back on the first Sunday in April.

These two are in opposite hemispheres, so their summers do not overlap: Denver is on summer time roughly when Auckland is not. The gap does not wobble by an hour around a settled figure — it swings between 18 hours and 20 hours and spends a good part of the year at each. There is no single right answer to give a calendar, which is why a recurring meeting between them is worth setting in one city's local time and letting the other side see it move.

When they can both be at their desks

Nine-to-five in Denver and nine-to-five in Auckland do not overlap at all. With 18 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
