About converting AEST to IST
Australian Eastern Time (Sydney) and India Standard Time (India) are in different time zones, so a meeting, call or stream that's convenient in one may be early or late in the other. The clocks above update live and account for daylight saving automatically, so the time difference you see is the real one for today — not a fixed number that goes stale twice a year.
To plan across the two, type a time into the AEST box (or tap a quick preset) and read the IST equivalent, including a "next day" or "previous day" note when the conversion crosses midnight. For any other pair of zones or cities, use the full timezone converter.
AEST vs IST: the time difference through the year
The gap between AEST and IST changes during the year because only one of them uses daylight saving.

The two zones
Sydney is on AEST (UTC+10) from April to October and on daylight-saving AEDT (UTC+11) from the first Sunday in October to the first Sunday in April. Queensland (Brisbane) stays on AEST all year.
India Standard Time is UTC+5:30 all year — one of the few half-hour offsets. India uses a single time zone and has no daylight saving.
