Why people convert AEDT to SGT time
- Scheduling a call from AEDT to SGT: a 10:00 AM start in AEDT lands at 7:00 AM in SGT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both AEDT and SGT are inside the 9-to-5 working day between 12:00 PM and 5:00 PM AEDT time (9:00 AM–2:00 PM SGT). That is roughly 5 hours of usable overlap.
- Booking travel or deliveries: tracking SGT local time against AEDT keeps pickup windows and arrival estimates honest across the -3h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM AEDT" is unambiguous; "3 PM" across a -3h gap is not.
- Block 12:00 PM–5:00 PM AEDT as the recurring meeting window if you work primarily from AEDT and need SGT colleagues present.
About AEDT (Australian Eastern Daylight Time)
Australian Eastern Daylight Time (AEDT) is the daylight saving period in south-eastern Australia, one hour ahead of Australian Eastern Standard Time (AEST, UTC+10:00). Because Australia is in the southern hemisphere, AEDT runs through the summer — from the first Sunday in October to the first Sunday in April — which is almost exactly the reverse of the European and North American schedules. New South Wales, Victoria, Tasmania and the Australian Capital Territory observe it; Queensland and the Northern Territory do not, so Brisbane stays on AEST year round while Sydney moves to AEDT. During AEDT, Sydney is 11 hours ahead of UTC and 16 hours ahead of New York.
About SGT (Singapore Standard Time)
Singapore Standard Time (SGT) is used in Singapore year-round. Singapore does not observe daylight saving time. Despite being geographically close to the UTC+07:00 zone, Singapore uses UTC+08:00 to align with major trading partners like China, Hong Kong, and Malaysia. Singapore is a major global financial hub.
Best time to call between AEDT and SGT
Both AEDT and SGT sit inside the 9 AM – 5 PM working day between 12:00 PM–5:00 PM AEDT, which is 9:00 AM–2:00 PM SGT. That gives roughly 5 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
AEDT and SGT share 5 hours of working-hours overlap (12:00 PM–5:00 PM AEDT), so scheduling a live meeting is straightforward.
AEDT is 3 hours behind SGT (AEDT UTC+11:00 → SGT UTC+08:00). The shared working window is 12:00 PM–5:00 PM AEDT. Remember to re-check around daylight-saving transitions.
