IST to Berlin
India is 3 hours and 30 minutes ahead of Berlin.
Times may vary due to daylight saving time.Quick answer. Berlin is 4 hours and 30 minutes behind IST for part of the year and 3 hours and 30 minutes behind for the rest, because Berlin observes daylight saving time and the other side does not. The gap is 4 hours and 30 minutes during Berlin's standard-time months and 3 hours and 30 minutes during daylight time, so always convert against a specific date.

Comparing a 9:00–18:00 working day in IST against 9:00–17:00 in Berlin, across the whole week — a slot only counts if it lands on a working day at both ends.

Public holidays

| Date | Who is off | Holiday |

Festival dates follow lunisolar calendars and move every year, so they are listed explicitly rather than derived.

About this conversion
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 IST and Berlin?
It depends on the date. Berlin is 4 hours and 30 minutes behind IST in January and 3 hours and 30 minutes behind in July, because Berlin changes clocks for daylight saving time. Use the converter above with the date you actually need.
What time is 9 AM IST in Berlin?
9:00 AM IST is 4:30 AM in Berlin during CET, and 5:30 AM during CEST. 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 Berlin?
Working days overlap for about 5 hours on a typical Monday: 1 PM to 6 PM IST, which is 9:30 AM to 2:30 PM in Berlin. For a recurring invite, 1 PM IST / 9:30 AM Berlin 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 Berlin comes entirely from the other side.
When do the clocks change in Berlin?
In 2026, clocks in Berlin 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 IST–Berlin difference change during the year?
Because Berlin 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 IST and Berlin actually overlap?
25 hours across the week, spread over 5 working days. 1 PM IST (9:30 AM Berlin) 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 Berlin line up?
Barely. Over the next eight weeks the two sides share 40 working days, and 2 of those are a public holiday on one side or the other, leaving 38. The next holiday in Berlin is World Children's Day (Weltkindertag) on 2026-09-20. Indian, Gulf and Western holiday calendars are built on different systems, so the days each side loses rarely coincide.
Is IST ahead of Berlin?
Yes. IST runs ahead of Berlin — by 3 hours and 30 minutes or 4 hours and 30 minutes depending on the season, so a working morning in IST lands the previous evening or night in Berlin.
