Zurich to IST
Zurich is 3 hours and 30 minutes behind India Standard Time.
Times may vary due to daylight saving time.Quick answer. IST is 4 hours and 30 minutes ahead of Zurich for part of the year and 3 hours and 30 minutes ahead for the rest, because Zurich observes daylight saving time and the other side does not. The gap is 4 hours and 30 minutes during Zurich's standard-time months and 3 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 Zurich 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.

Frequently asked questions
What is the time difference between Zurich and IST?
It depends on the date. IST is 4 hours and 30 minutes ahead of Zurich in January and 3 hours and 30 minutes ahead in July, because Zurich changes clocks for daylight saving time. Use the converter above with the date you actually need.
What time is 9 AM Zurich in IST?
9:00 AM Zurich is 1:30 PM in IST during IST, and 12:30 PM 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 Zurich and IST?
Working days overlap for about 4 hours on a typical Monday: 9 AM to 1 PM Zurich, which is 12:30 PM to 4:30 PM in IST. For a recurring invite, 12 PM Zurich / 3:30 PM IST is the slot that works on the most days.
Does Zurich observe daylight saving time?
Yes. Zurich alternates between CET (UTC+1:00) and CEST (UTC+2:00). In 2026, clocks in Zurich go forward on March 29, 2026 and back on October 25, 2026. India does not shift at all, so the gap between the two moves twice a year.
When do the clocks change in Zurich?
In 2026, clocks in Zurich go forward on March 29, 2026 and back on October 25, 2026. Between those dates the gap from India is 3 hours and 30 minutes; outside them it is 4 hours and 30 minutes.
Why does the Zurich–IST difference change during the year?
Because Zurich switches between CET (UTC+1:00) and CEST (UTC+2:00) 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 Zurich and IST actually overlap?
20 hours across the week, spread over 5 working days. 12 PM Zurich (3:30 PM 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 Zurich and IST line up?
Barely. Over the next eight weeks the two sides share 40 working days, and 3 of those are a public holiday on one side or the other, leaving 37. 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 Zurich ahead of IST?
No, it is the other way around: IST is ahead of Zurich by 3 hours and 30 minutes to 4 hours and 30 minutes.
