Australian Eastern Time follows the clock in Sydney: AEST (UTC+10) in the southern winter and AEDT (UTC+11) from the first Sunday in October to the first Sunday in April.
Queensland, including Brisbane, stays on AEST all year. For Brisbane, pick Australia/Brisbane in the converter.
India Standard Time is UTC+5:30 all year. The whole country keeps a single clock, and India has not observed daylight saving time since the 1940s, so IST never changes.
IST can also stand for Irish Standard Time or Israel Standard Time. On this site IST always means India Standard Time (Asia/Kolkata).
IST is 5 hours 30 minutes behind AEDT for most of the year (183 days in 2026). The gap is 4 hours 30 minutes for most of the year (182 days in 2026).
