Time Difference: India and Sydney
Sydney is 4 hours 30 minutes ahead of India on AEST and 5 hours 30 minutes ahead on AEDT. 9:00 AM in India is 1:30 PM in Sydney on AEST and 2:30 PM on AEDT.
AEST or AEDT: Which Gap Applies
India is UTC+5:30 all year and never changes its clocks. Sydney is UTC+10 on AEST and UTC+11 on AEDT.
| Sydney is on | Gap from India |
|---|---|
| AEDT, first Sunday in October to first Sunday in April | 5 hours 30 minutes |
| AEST, first Sunday in April to first Sunday in October | 4 hours 30 minutes |
Sydney's summer time runs through the northern winter, so its clock changes are the opposite of the UK and US ones. When Europe and America move forward in March, Sydney moves back a few weeks later. Sydney's calendar says "AEST" only from April to October, so a message that says AEST for a summer date is an hour out.

A Few Hours at the End of the India Morning
On AEST, 9:00 AM to 12:30 PM in India is 1:30 PM to 5:00 PM in Sydney, 3 hours 30 minutes. On AEDT the window shrinks to 9:00 to 11:30 AM in India, which is 2:30 PM to 5:00 PM in Sydney, 2 hours 30 minutes. Sydney's 5 PM close is the limit both times.
2:00 PM in India is 6:30 PM in Sydney on AEST and 7:30 PM on AEDT. And 9:00 AM in Sydney is 4:30 AM in India on AEST and 3:30 AM on AEDT.
A call at 10:00 AM India time is 2:30 PM in Sydney on AEST but 3:30 PM on AEDT. Name Sydney as a city in the invite instead of using an abbreviation.
A 10 AM India Call With Sydney
An India team scheduling a 10:00 AM call with Sydney gets 2:30 PM in Sydney on AEST and 3:30 PM on AEDT. An 11:00 AM start in India is 3:30 PM on AEST and 4:30 PM on AEDT.
If Sydney hosts at 3:00 PM, India joins at 10:30 AM on AEST and 9:30 AM on AEDT. India's side moves by an hour at the Sydney clock changes, so a Sydney-hosted series needs a reminder in early April and early October.
