AEST to IST Converter – Convert Australian Time to India Standard Time

Australian Eastern Standard Time (AEST) and India Standard Time (IST) are quite common in the Asia-Pacific area. If you're working with Indian teams, setting up online meetings, or arranging global events, knowing how to change AEST to IST is really important. Here's a quick converter to help you figure out the time difference between Australia and India!

What's AEST?

AEST, or Australian Eastern Standard Time, is UTC +10. Big Aussie states such as New South Wales, Victoria, Queensland, Tasmania, and the Australian Capital Territory time themselves accordingly. You'll find AEST in cities like Sydney, Melbourne, Brisbane, and Canberra. When daylight saving rolls around, AEST turns into AEDT (Australian Eastern Daylight Time).

What's IST?

IST, short for India Standard Time, is UTC +5:30. This time is used all over India and Sri Lanka. IST stays the same all year because it doesn't have daylight saving. Big cities like Delhi, Mumbai, Bengaluru, Chennai, and Kolkata all run on IST.

AEST and IST: What's the Time Difference?

The easy answer is that AEST is 4 hours and 30 minutes ahead of IST. Here are some quick examples:

Quick Note About Daylight Saving

Just remember that AEST switches to AEDT when Australia does daylight saving. Since IST doesn't do daylight saving, the time difference might shrink to 3 hours and 30 minutes during that time. Always make sure to check those daylight saving changes when you're setting up meetings!
