Bucharest is 3.5 hours behind Chennai
Best overlap: 12:00 PM to 6:00 PM in Chennai is 8:30 AM to 2:30 PM in Bucharest.
For a call that suits both sides, look at 12:00 PM to 6:00 PM in Chennai / 8:30 AM to 2:30 PM in Bucharest. Bucharest is 3.5 hours behind Chennai, but the generous 6-hour window means both teams can meet well within their normal day. These times hold for most of the year, but Bucharest's daylight saving (which Chennai doesn't use) shifts them by an hour twice annually.
