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.
When it's 12:00 PM IST, it's 7:30 AM CET

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.
