Hyderabad is 4.5 hours behind Melbourne
Best overlap: 1:00 PM to 6:00 PM in Melbourne is 8:30 AM to 1:30 PM in Hyderabad.
Keep meetings inside 1:00 PM to 6:00 PM in Melbourne — that maps to 8:30 AM to 1:30 PM in Hyderabad. Around 5 hours of overlap is enough to work comfortably, as long as meetings don't drift to the end of one team's day. Finally, Melbourne observes daylight saving and Hyderabad doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
