IST to Auckland
India is 6 hours and 30 minutes behind Auckland.
Times may vary due to daylight saving time.Quick answer. Auckland is 7 hours and 30 minutes ahead of IST for part of the year and 6 hours and 30 minutes ahead for the rest, because Auckland observes daylight saving time and the other side does not. The gap is 7 hours and 30 minutes during Auckland's standard-time months and 6 hours and 30 minutes during daylight time, so always convert against a specific date.

India has three national holidays on which the whole country closes. Everything else is either a central-government gazetted holiday that individual employers choose to observe, or a state holiday. Festival dates follow lunisolar calendars and move every year, so they are listed explicitly rather than derived.

Frequently asked questions
What is the time difference between IST and Auckland?
It depends on the date. Auckland is 7 hours and 30 minutes ahead of IST in January and 6 hours and 30 minutes ahead in July, because Auckland changes clocks for daylight saving time. Use the converter above with the date you actually need.
What time is 9 AM IST in Auckland?
9:00 AM IST is 4:30 PM in Auckland during NZST, and 3:30 PM during NZDT. The table on this page lists all 24 hours for the date you pick.
What is the best time for a meeting between IST and Auckland?
Working days overlap for about 1 hour on a typical Monday: 9 AM to 10 AM IST, which is 3:30 PM to 4:30 PM in Auckland. For a recurring invite, 9 AM IST / 3:30 PM Auckland is the slot that works on the most days.
Does India observe daylight saving time?
No. India has kept a single UTC+5:30 offset since 1945 and does not use daylight saving time, so IST reads the same on every date of the year. Any change in the gap to Auckland comes entirely from the other side.
When do the clocks change in Auckland?
In 2026, clocks in Auckland go forward on September 27, 2026 and back on April 5, 2026. Between those dates the gap from India is 6 hours and 30 minutes; outside them it is 7 hours and 30 minutes.
Why does the IST–Auckland difference change during the year?
Because Auckland switches between NZST (UTC+12:00) and NZDT (UTC+13:00) for daylight saving, while the other side does not move. A converter that assumes one fixed gap will be an hour wrong for roughly half the year.
How many hours a week do IST and Auckland actually overlap?
5 hours across the week, spread over 5 working days. 9 AM IST (3:30 PM Auckland) is the slot that works on the most days, so it is the one to put in a recurring invite.
Do public holidays in IST and Auckland line up?
Barely. Over the next eight weeks the two sides share 40 working days, and 6 of those are a public holiday on one side or the other, leaving 34. The next holiday in Auckland is Canterbury (South) Anniversary Day (Dominion Day) on 2026-09-28. Indian, Gulf and Western holiday calendars are built on different systems, so the days each side loses rarely coincide.
Is IST ahead of Auckland?
No, it is the other way around: Auckland is ahead of IST by 6 hours and 30 minutes to 7 hours and 30 minutes.
