CET vs IST — Europe to India

CET (UTC+1) — Central European Time, covering Germany, France, Italy, Spain, Netherlands, and ~20 more countries. Shifts to CEST (UTC+2) in summer.

IST (UTC+5:30) — India Standard Time, fixed year-round with no DST. The half-hour offset produces :00 or :30 minute results in all conversions.

The Europe–India IT corridor is one of the busiest in the world. Best overlap: 10 AM–2 PM CET = 2:30–6:30 PM IST. Frankfurt and Bangalore engineering teams typically use 11:00 AM–1:00 PM CET for standups.

Frequently Asked Questions

How many hours is CET behind IST?

CET (UTC+1) is 4 hours 30 minutes behind IST (UTC+5:30). During European summer (CEST, UTC+2), the gap narrows to 3 hours 30 minutes. India does not observe DST, so the offset only changes when Europe shifts clocks in late March and late October.

What is 9 AM CET in IST?

9:00 AM CET (Frankfurt/Berlin) is 1:30 PM IST. During CEST (European summer), 9:00 AM CEST = 12:30 PM IST. The best CET–IST overlap for business is 10:00 AM–1:00 PM CET = 2:30–5:30 PM IST (winter) or 10:00 AM–1:00 PM CEST = 1:30–4:30 PM IST (summer).

What is the best time to call India from Germany or France?

In winter (CET): 10:00 AM–2:00 PM CET = 2:30–6:30 PM IST. In summer (CEST): 10:00 AM–2:00 PM CEST = 1:30–5:30 PM IST. European mornings and early afternoons comfortably reach Indian afternoons within business hours on both sides.

Does the CET to IST gap change in summer?

Yes, partially. India has no DST, so the change comes only from the European side. In winter (CET, UTC+1): 4.5 hours behind IST. In summer (CEST, UTC+2): 3.5 hours behind IST. The gap shifts once in late March (clocks go forward in Europe) and once in late October (clocks go back).
