Best time to schedule a meeting

Frequently asked questions
How many hours ahead is Mumbai of Sydney?
It depends on the season. Around July Mumbai is 4 hours 30 minutes behind Sydney; around January it is 5 hours 30 minutes behind Sydney. The switch happens when one of the two moves to or from daylight saving time.
What time is 12:00 noon IST in AEST?
12:00 noon IST is 16:30 AEST.
Does IST or AEST use daylight saving time?
IST does not observe daylight saving; AEST does. The difference between them changes twice a year, when Sydney shifts its clocks.
