Hyderabad is 2.5 hours ahead of Helsinki
Best overlap: 8:30 AM to 3:30 PM in Helsinki is 11:00 AM to 6:00 PM in Hyderabad.
If you set up a recurring sync, 8:30 AM to 3:30 PM in Helsinki (11:00 AM to 6:00 PM in Hyderabad) is the natural home for it. Despite the 2.5-hour difference, a 7-hour overlap keeps things simple and gives both teams breathing room. These times hold for most of the year, but Helsinki's daylight saving (which Hyderabad doesn't use) shifts them by an hour twice annually.
