Frequently Asked Questions

How many hours behind is CET from IST?

Central European Time (CET) is 4 hours and 30 minutes behind India Standard Time (IST) during winter, and 3 hours and 30 minutes behind during summer (CEST). When it's 12:00 PM IST in Mumbai, it's 7:30 AM CET in Berlin during winter or 8:30 AM CEST during summer.

What time is it in Germany when it's 9 AM in Mumbai?

When it's 9:00 AM IST in Mumbai, it's 4:30 AM CET in Germany during winter or 5:30 AM CEST during summer. Other practical conversions include 12 PM Mumbai = 7:30 AM Germany (winter) or 8:30 AM (summer), and 6 PM Mumbai = 1:30 PM Germany (winter) or 2:30 PM (summer).

What time is it in Mumbai when it's 9 AM in Berlin?

When it's 9:00 AM CET in Berlin, it's 1:30 PM IST in Mumbai during winter or 12:30 PM IST during summer (CEST). Key conversions include 8 AM Berlin = 12:30 PM Mumbai (winter) or 11:30 AM (summer), and 2 PM Berlin = 6:30 PM Mumbai (winter) or 5:30 PM (summer).

Which countries and cities use IST and CET time zones?

IST (India Standard Time) covers all Indian cities, including Mumbai, Delhi, Bangalore, Chennai, and Kolkata. CET (Central European Time) includes major European cities like Berlin, Paris, Rome, Madrid, Amsterdam, Vienna, and Prague. CET covers most of Europe, including Germany, France, Italy, Spain, the Netherlands, and Poland.

When does CET change to CEST and how does it affect IST conversion?

CET changes to CEST on the last Sunday in March (March 30, 2025) and returns to CET on the last Sunday in October (October 26, 2025). During the CET period (October-March), India is 4.5 hours ahead of Europe. During the CEST period (March-October), India is 3.5 hours ahead. India never observes daylight saving time.

What's the best time for business meetings between India and Europe?

The optimal meeting window is 12:30 PM to 6:00 PM IST, corresponding to 8:00 AM to 1:30 PM CET/CEST in Europe. This allows perfect overlap between Indian afternoon hours and European morning business hours. Avoid scheduling before 12:30 PM IST or after 6:00 PM IST for comfortable timing on both sides.

Do India and Europe business hours overlap well?

Yes, there's good overlap! India's business hours (9 AM-6 PM IST) align with European mornings and early afternoons (7:30 AM-1:30 PM CET in winter, 8:30 AM-2:30 PM CEST in summer). The sweet spot is 12:30-6 PM India time, which equals 8 AM-1:30 PM in Europe, making collaboration much easier than US time zones.

What's the quickest way to convert IST to CET time?

The fastest method is subtracting 4.5 hours from Indian time during European winter (CET) or 3.5 hours during European summer (CEST). For smartphone users, add "Berlin" or "Paris" to your world clock widget, or ask Siri/Google Assistant, "What time is it in Germany?" For instant conversion, visit iformat.io.
