Auckland to IST
Auckland is 6 hours and 30 minutes ahead of India Standard Time.
Times may vary due to daylight saving time.Quick answer. IST is 7 hours and 30 minutes behind Auckland for part of the year and 6 hours and 30 minutes behind 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.
Holiday dates for Auckland and elsewhere come from a dataset last refreshed on 2026-09-12 (date.nager.at plus curated national calendars). Lunar dates — Eid, Chinese New Year, the Jewish holidays — are predicted and can move by a day once officially announced. Regional, state and employer-specific holidays are not included.

About this conversion
NZST/NZDT
India runs on a single time zone, UTC+5:30, and has not observed daylight saving time since 1945. The half-hour offset is why IST conversions rarely land on a round hour.
Frequently asked questions
What is the time difference between Auckland and IST?
It depends on the date. IST is 7 hours and 30 minutes behind Auckland in January and 6 hours and 30 minutes behind 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 Auckland in IST?
9:00 AM Auckland is 1:30 AM in IST during IST, and 2:30 AM during daylight time. The table on this page lists all 24 hours for the date you pick.
What is the best time for a meeting between Auckland and IST?
Working days overlap for about 2 hours on a typical Monday: 4 PM to 6 PM Auckland, which is 9:30 AM to 11:30 AM in IST. For a recurring invite, 4 PM Auckland / 9:30 AM IST is the slot that works on the most days.
Does Auckland observe daylight saving time?
Yes. Auckland alternates between NZST (UTC+12:00) and NZDT (UTC+13:00). In 2026, clocks in Auckland go forward on September 27, 2026 and back on April 5, 2026. India does not shift at all, so the gap between the two moves twice a year.
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 Auckland–IST 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 Auckland and IST actually overlap?
10 hours across the week, spread over 5 working days. 4 PM Auckland (9:30 AM IST) is the slot that works on the most days, so it is the one to put in a recurring invite.
Do public holidays in Auckland and IST 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 IST is Gandhi Jayanti on 2026-10-02. Indian, Gulf and Western holiday calendars are built on different systems, so the days each side loses rarely coincide.
Is Auckland ahead of IST?
Yes. Auckland runs ahead of IST — by 6 hours and 30 minutes or 7 hours and 30 minutes depending on the season, so a working morning in Auckland lands the previous evening or night in IST.
