India Standard Time to Australian Eastern Time: live clocks, today's full conversion table, and the best hours to call. Daylight saving is handled automatically.
About IST and AEST
India Standard Time (IST) is used across all of India, including Mumbai, Delhi, Bengaluru, Chennai and Kolkata. India does not observe daylight saving time.
Australian Eastern Time (AEST/AEDT) is used in Sydney, Melbourne, Canberra and Brisbane. Sydney and Melbourne shift to AEDT from October to April; Brisbane stays on AEST.
Time difference between IST and AEST
AEST is 5 hours 30 minutes ahead of IST in winter (January) and 4 hours 30 minutes ahead of IST in summer (July), because of daylight saving changes. The clocks and table above are computed live from the official IANA time zone database in your browser, so daylight saving transitions are always already included.
