Frequently Asked Questions

How many hours ahead is IST from CET and why does it change?

India Standard Time (IST) is 4 hours and 30 minutes ahead of Central European Time (CET) during winter, and 3 hours and 30 minutes ahead during European summer time (CEST). The difference changes because Europe observes daylight saving time from March to October, while India never changes its clocks, staying at UTC+5:30 year-round.

What time is it in Mumbai when it's 2 PM in Berlin?

When it's 2:00 PM CET in Berlin during winter, it's 6:30 PM IST in Mumbai. During summer, when Berlin is on CEST, 2:00 PM Berlin equals 5:30 PM IST in Mumbai. The one-hour seasonal shift makes this timing perfect for end-of-workday calls from Europe to evening hours in India.

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

When it's 9:00 AM IST in Delhi, it's 4:30 AM CET in Berlin during winter or 5:30 AM CEST during summer. This early European time makes morning meetings in India challenging for European participants. Consider scheduling Indian afternoon meetings (2-6 PM IST), equivalent to comfortable European morning hours (9:30 AM-1:30 PM CET/CEST).

Which European cities use CET and how do they align with Indian business hours?

Major CET cities include Berlin, Paris, Rome, Madrid, Amsterdam, Vienna, and Prague. CET business hours (9 AM-5 PM) align with Indian afternoon/evening hours (1:30-9:30 PM IST in winter, 12:30-8:30 PM during summer). The best meeting overlap is 9 AM-1 PM European time, equaling 1:30-5:30 PM in India.

When does CET change to CEST and how does it affect India meetings?

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 CEST period (March-October), the time gap with India reduces by one hour, making European-Indian collaboration slightly easier with better meeting window alignment and less jet lag for travelers.

Do Europe and India business hours overlap well for international collaboration?

Yes, there's excellent overlap! European business hours (9 AM-5 PM CET/CEST) align perfectly with Indian afternoon hours (1:30-9:30 PM IST). The sweet spot is 10 AM-1 PM European time, which equals 2:30-5:30 PM in India during summer or 3:30-6:30 PM during winter. This 3-4 hour daily overlap makes Europe-India collaboration much more manageable than US-India partnerships.

How does the CET-IST time difference affect travel and jet lag?

Flying from Europe to India (eastbound) involves a 4.5-5.5 hour time difference, causing moderate jet lag as you "lose time." Westbound travel from India to Europe is generally easier for jet lag recovery. European afternoon flights (2-4 PM CET) arrive in India during comfortable evening hours (6:30-8:30 PM IST), while Indian evening flights arrive in Europe the next morning.

How do I avoid scheduling mistakes when planning Europe-India meetings?

Always specify both time zones when scheduling (e.g., "2 PM CET/6:30 PM IST") and double-check if Europe is on CET or CEST during your meeting date. Use calendar apps that auto-convert time zones, set recurring meetings for the same European time to maintain consistency, and send calendar invites with both local times displayed. Avoid scheduling during European daylight saving transition weeks in March and October.
