Best overlap: 8:30 AM to 1:30 PM in Chennai is 1:00 PM to 6:00 PM in Sydney.
Your window to reach both cities is 8:30 AM to 1:30 PM in Chennai, which converts to 1:00 PM to 6:00 PM in Sydney. Sydney is 4.5 hours ahead of Chennai, leaving about 5 hours of shared hours — plan recurring calls early in that window to leave buffer. One seasonal catch: Sydney springs forward and falls back, but Chennai doesn't, so the gap changes by an hour for several months of the year.
