Frequently Asked Questions
What is the time difference between KST and NZST?
During standard time, New Zealand Standard Time is 3 hours ahead of Korea Standard Time.
Does South Korea observe Daylight Saving Time?
South Korea does not observe Daylight Saving Time and has not done so since 1988, when DST was discontinued following the Seoul Summer Olympics. KST remains fixed at UTC+9:00 every day of the year, meaning the offset between Seoul and any DST-observing country shifts by one hour twice annually when those countries change their clocks.
Are KST and JST the same?
Yes, Korea Standard Time (KST) and Japan Standard Time (JST) share the identical UTC+9:00 offset, and neither country observes Daylight Saving Time. Seoul and Tokyo run on exactly the same clock year-round, which directly supports the deep semiconductor, automotive, and consumer electronics supply chain integration between the two economies.
Does New Zealand observe Daylight Saving Time?
New Zealand observes Daylight Saving Time annually, advancing clocks to New Zealand Daylight Time (NZDT) at UTC+13:00 on the last Sunday of September and returning to NZST (UTC+12:00) on the first Sunday of April. In 2026, clocks spring forward on September 27 and fall back on April 5 — following the Southern Hemisphere calendar, which runs opposite to DST schedules in Europe and North America.
Why does Antarctica use New Zealand Time?
McMurdo Station and Amundsen-Scott South Pole Station — the two largest US Antarctic research bases — operate on NZST and NZDT because their primary supply and personnel flights operate out of Christchurch International Airport in New Zealand. Aligning base operations with New Zealand time eliminates scheduling complexity across the Christchurch–McMurdo logistics chain, which handles all cargo, fuel, and personnel rotations for the US Antarctic Program.
