Convert IST to CET

India Standard Time (IST) to Central European Time (CET)

Indian IT companies and consulting firms with European clients in Germany, France, and the Netherlands convert IST to CET daily for project calls, sprint reviews, and support rotations. The 4.5-hour gap during CET (3.5 during CEST in summer) provides a generous overlap window, making India-Europe one of the more manageable intercontinental timezone pairings for distributed teams.

Scheduling Tips

  • Schedule between 1:30-5:30 PM IST / 9:00 AM-1:00 PM CET for the most productive overlap. Both teams are in core hours.
  • During CEST (summer), you get an extra hour of overlap. Use 12:30-5:30 PM IST / 9:00 AM-2:00 PM CEST for wider flexibility.
  • For daily standups, 1:30 PM IST / 9:00 AM CET is the earliest comfortable slot that works for both sides.

Frequently Asked Questions

What is the time difference between IST and CET?
IST (UTC+5:30) is 4 hours and 30 minutes ahead of CET (UTC+1). When it is 3:00 PM in India, it is 10:30 AM in Berlin. During Central European Summer Time (CEST, UTC+2, late March to late October), the gap narrows to 3 hours and 30 minutes.
What is 9:00 AM IST in Central European Time?
9:00 AM IST is 4:30 AM CET -- too early for European offices. Indian morning hours do not overlap with Europe. The productive overlap starts in the Indian afternoon.
Does the IST to CET time difference change during the year?
Yes, but only on the European side. India does not observe DST. When Europe shifts to CEST (UTC+2) from late March to late October, the gap narrows from 4.5 to 3.5 hours, giving teams an extra hour of overlap during European summer.
When is the best time for a call from India to Europe?
The best window from India is 1:30–6:30 PM IST, which maps to 9:00 AM–2:00 PM CET. During CEST (summer), the same IST window maps to 10:00 AM–3:00 PM CEST. Indian afternoons overlap with the European core workday. Use the Meeting Planner to score each slot for your team's specific hours.
