AEST to IST Conversion Guide

What is AEST to IST Conversion?

AEST to IST conversion helps you translate time between Australian Eastern Standard Time and India Standard Time. AEST is always UTC+10 and never changes for daylight saving time. IST is always UTC+5:30 and serves as the single time zone for all of India, never observing daylight saving time.

Time Zone Information

Australian Eastern Standard Time (AEST): Used throughout eastern Australia including Sydney, Melbourne, Brisbane, and Canberra. Always UTC+10 with no daylight saving time adjustments.

India Standard Time (IST): Used throughout all of India including Mumbai, Delhi, Bangalore, and Kolkata. Always UTC+5:30 with no daylight saving time adjustments.

Time Difference: AEST is always 4 hours and 30 minutes ahead of IST. This difference never changes throughout the year.

Why These Time Zones Don't Change

Australia (AEST): Only certain Australian states observe daylight saving, but AEST specifically never changes

India (IST): India uses a single time zone across the entire country and does not observe daylight saving time

Consistency: This makes AEST to IST conversion very reliable and consistent year-round
