How Time Zone Conversion Works
Time zone conversion works by comparing the UTC offset of one location to another. Every city or region is measured relative to Coordinated Universal Time (UTC), which acts as the global reference point for civil time.
AEST is 4 hours 30 minutes ahead of IST (standard time).
Daylight Saving Time: Neither IST nor AEST observes Daylight Saving Time. The 4h 30m offset is constant year-round with no seasonal variation.

Current-year daylight saving start and end dates for the selected zones.
IST · India Time
Standard offset +05:30
India Time remains on a constant standard offset for the year.
India does not observe daylight saving time. The IST offset of UTC+5:30 is constant year-round. Note: 'IST' is sometimes ambiguous — it can also refer to Irish Standard Time (Ireland's summer time). On TimeAtlas, IST refers exclusively to India Standard Time.
AEST · Eastern Australia Time
Standard offset +10:00
Eastern Australia Time remains on a constant standard offset for the year.
This record represents the year-round UTC+10 designation used in Queensland, which does not observe DST. NSW, Victoria, Tasmania, and ACT use AEST as the winter half of a cycle that transitions to AEDT (UTC+11) in summer — see the AEDT record for those DST dates and rules.
