When the difference changes

India Standard Time and Central European Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  1. Now – March 28, 2027Central European Time is 4 hours 30 minutes behind
  2. March 28, 2027 – October 31, 2027Central European Time is 3 hours 30 minutes behind
  3. October 31, 2027 – onwardsCentral European Time is 4 hours 30 minutes behind

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Daylight saving

India Standard Time

No clock changes

India Standard Time stays on IST all year, so its offset from UTC never moves.

Central European Time

Sunday, March 28, 2027

Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on CEST after that.

Scheduling between the two

Working hours overlap from 2:00 pm to 6:00 pm IST, which is 9:30 am to 1:30 pm CET. Anything inside that window falls in the normal working day at both ends.

A note on IST: it can also mean Israel Standard Time (UTC+2) and Irish Standard Time (UTC+1). This page means India Standard Time, which is what almost all searches for IST want.

India Standard Time (IST) is used in all of India and Sri Lanka, on a single UTC+5:30 offset with no daylight saving

Central European Time (CET) is used in Berlin, Madrid, Rome, Amsterdam, Warsaw and Stockholm
