Frequently Asked Questions
What is the time difference between NZST and IST?
During standard time, Indian Standard Time is 6.5 hours behind New Zealand Standard Time.
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.
Does India observe Daylight Saving Time (DST)?
India does not observe Daylight Saving Time and has not done so since 1945. IST remains fixed at UTC+5:30 every day of the year, meaning the offset between India and any DST-observing country shifts by one hour twice annually when those countries change their clocks.
Why does IST have a 30-minute offset?
India chose the 82.5° East meridian — which passes through Mirzapur in Uttar Pradesh — as its central reference longitude, as it bisects the subcontinent geographically. That meridian sits exactly 5 hours and 30 minutes ahead of the Prime Meridian in Greenwich, producing the UTC+5:30 offset that has defined IST since 1906.
