Timezone converter
AEDT to IST currently uses Australian Eastern Time in Australia/Sydney and India Time in Asia/Kolkata as the live reference pair, with a -4h 30m live gap. AEDT to IST matters whenever Sydney and Mumbai need to coordinate across a -4h 30m gap. The AEDT side covers Australia, while IST covers India and Israel — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.
Last updated Apr 26, 2026. Offset math, DST behavior, and city coverage on both sides are refreshed from the live timezone dataset during the page revalidation window.
IST is ambiguous in this dataset, so the live converter uses Asia/Kolkata as the busiest reference zone while the city list below shows the wider label family.

Based on the busiest city and zone usage found in the current dataset.
AEDT (Sydney, +10:00) to IST (Mumbai, +05:30) is currently a -4h 30m conversion. Live coverage on the AEDT side is anchored by Sydney, Brisbane, Gold Coast, and Newcastle; the IST side draws from Mumbai, Delhi, Bengaluru, and Hyderabad.
AEDT to IST matters whenever Sydney and Mumbai need to coordinate across a -4h 30m gap. The AEDT side covers Australia, while IST covers India and Israel — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.
The pair sits -4h 30m apart across Oceania and Asia, which usually allows a meaningful shared workday on at least one end.
AEDT follows seasonal clock changes through Australia/Sydney, while IST stays on a fixed offset year-round. That asymmetry is the real differentiator on this page: the gap widens or narrows by an hour twice a year, so calendar invites scheduled in one season often look wrong in the other.
AEDT and IST sit 4h 30m apart, with about 3.5h of shared 9-to-5 time. That is enough room for one daily standup plus one focused working session, which is what most cross-region teams actually use this overlap for.
AEDT coverage on this page is led by Sydney, Australia, Brisbane, Australia, Gold Coast, Australia, and Newcastle, Australia, with 2 more in the live dataset. That mix is what makes AEDT feel anchored to Oceania and Pacific business activity in practice rather than just an abbreviation on a chart.
IST coverage is led by Mumbai, India, Delhi, India, Bengaluru, India, and Hyderabad, India, with 2 more anchoring the wider label family. Combined with the AEDT side, this conversion ends up describing cross-region coordination that uses the morning-on-one-side, afternoon-on-the-other window for live work.
