Explanation
The International Date Line (IDL) serves as the boundary where the calendar date changes by one day. New Zealand is located to the west of the IDL and follows New Zealand Daylight Time (UTC+13) during December. In contrast, the Hawaiian Islands (UTC-10) and Alaska (UTC-9) are located to the east of the IDL [1]. When crossing the IDL from west to east, the calendar is turned back by one day. Consequently, New Zealand is approximately 22 to 23 hours ahead of Hawaii and 21 to 22 hours ahead of Alaska [1]. Therefore, while it is 31st December, 2023 in New Zealand, both the Hawaiian Islands and Alaska are still in the previous calendar day, which is 30th December, 2023 [1].
