Spot Date-Line Shifts at a Glance

AEST to IST FAQ

Quick answers about daylight saving time, date changes, business-hour overlap, and the most common scheduling questions between Australian Eastern Standard Time and India Standard Time.

What is the time difference between AEST and IST?

IST is 4 hours 30 minutes behind AEST. AEST is UTC +10:00 and IST is UTC +5:30 relative to UTC. AEST observes daylight saving but IST does not, so the gap between them shifts by one hour twice a year. In AEST winter the difference is 4 hours 30 minutes; in summer it changes by an hour.

When can AEST and IST have business-hour overlap?

Aim for 13:00–17:00 AEST, which is 09:00–13:00 IST. Both sides stay inside standard business hours.

Does AEST or IST observe daylight saving time?

AEST observes daylight saving but IST does not, so the gap between them shifts by one hour twice a year. In AEST winter the difference is 4 hours 30 minutes; in summer it changes by an hour.

How do I quickly convert AEST to IST?

To convert AEST to IST, add 4 hours 30 minutes subtract from the AEST time. Example: if it's 10:00 AM AEST, it's 06:00 IST that day. The live converter at the top of this page handles DST automatically.

Why convert AEST to IST?

Australian universities and companies with Indian engineering centers coordinate across this 4.5-hour gap (5.5 during Sydney summer). The Indian Ocean corridor — Mumbai-Sydney-Singapore — is increasingly important for Asia-Pacific business.

What's the overlap window?

AEST 1:00-5:00 PM = IST 8:30 AM-12:30 PM (winter). India starts morning, Australia finishes afternoon. During AEDT (summer) the gap widens to 5.5 hours; shift the meeting an hour earlier on the Indian side.
