Frequently Asked Questions
What is the time difference between AEDT and IST?
During standard time, Indian Standard Time is 5.5 hours behind Australian Eastern Daylight Time.
When does AEDT start and end?
AEDT begins on the first Sunday in October at 02:00 local time, when clocks spring forward one hour from AEST (UTC+10) to AEDT (UTC+11). It ends on the first Sunday in April at 03:00 local time, when clocks fall back to AEST. In 2026, AEDT starts on October 4 and ends on April 5 — following the Southern Hemisphere summer calendar, which runs opposite to DST schedules in Europe and North America.
Is Brisbane on AEDT?
No — Queensland, including Brisbane, does not observe Daylight Saving Time and remains on AEST (UTC+10) year-round. During the AEDT period from October through April, Sydney and Melbourne advance to UTC+11 while Brisbane stays at UTC+10, creating a one-hour gap between cities that share nearly the same longitude and are otherwise in the same time zone for the other six months of the year.
Does India observe Daylight Saving Time (DST)?
India does not observe Daylight Saving Time and has not done so since 1945. IST remains fixed at UTC+5:30 every day of the year, meaning the offset between India and any DST-observing country shifts by one hour twice annually when those countries change their clocks.
Why does IST have a 30-minute offset?
India chose the 82.5° East meridian — which passes through Mirzapur in Uttar Pradesh — as its central reference longitude, as it bisects the subcontinent geographically. That meridian sits exactly 5 hours and 30 minutes ahead of the Prime Meridian in Greenwich, producing the UTC+5:30 offset that has defined IST since 1906.
