What is the difference between Pacific time and New Zealand time?

Answer 1

Were it not for Daylight Savings Time, New Zealand would be 20 hours ahead of Pacific Time. But New Zealand is on Daylight Savings Time when the U.S. is not, and the U.S. is on Daylight Savings Time when New Zealand is not (except for the few weeks when both are on Daylight Savings or Standard Time).

So, during the middle of the year (approximately March/April through September/November) New Zealand is 19 hours ahead of Pacific Daylight Time. During the rest of the year (approximately September/November through March/April), New Zealand is 21 hours ahead of Pacific Standard Time.

From September 26 (when New Zealand begins Daylight Savings) to November 7 (when New York ends Daylight Savings), and from March 14 (when Daylight Savings begins in New York) to April 4 (when it ends in New Zealand), New Zealand is 17 hours ahead of New York.

Also, New Zealand's Chatham Islands are 45 minutes ahead of the mainland. So the Chatham Islands are 19 hours and 45 minutes ahead of the Pacific Time Zone during the middle of the year, 21 hours and 45 minutes ahead of the Pacific Time Zone during the rest of the year, and 20 hours and 45 minutes ahead during the few weeks when both places are on Daylight Savings or Standard Time.

So, in December, if it's 6 PM on Friday in California, it's 3 PM on Saturday in mainland New Zealand.

In July, if it's 6 PM Friday in California, then it's 1 PM Saturday in mainland New Zealand.

From September 26 to November 7, if it's 6 PM Friday in California, it's 2 PM Saturday in mainland New Zealand.

Also, from March 14 to April 4, if it's 6 PM Friday in California, it's 2 PM Saturday in mainland New Zealand.
