Why people convert SGT to AEDT time
- Scheduling a call from SGT to AEDT: a 10:00 AM start in SGT lands at 1:00 PM in AEDT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both SGT and AEDT are inside the 9-to-5 working day between 9:00 AM and 2:00 PM SGT time (12:00 PM–5:00 PM AEDT). That is roughly 5 hours of usable overlap.
- Watching a live event or market open: SGT viewers need 12:00 PM in AEDT to catch a 9:00 AM start there, and 9:00 PM if the event is anchored to SGT.
- Always state the zone abbreviation, not just the hour. "3:00 PM SGT" is unambiguous; "3 PM" across a +3h gap is not.
- Block 9:00 AM–2:00 PM SGT as the recurring meeting window if you work primarily from SGT and need AEDT colleagues present.
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.
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.
Best time to call between SGT and AEDT
Both SGT and AEDT sit inside the 9 AM – 5 PM working day between 9:00 AM–2:00 PM SGT, which is 12:00 PM–5:00 PM AEDT. That gives roughly 5 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
SGT and AEDT share 5 hours of working-hours overlap (9:00 AM–2:00 PM SGT), so scheduling a live meeting is straightforward.
SGT is 3 hours ahead of AEDT (SGT UTC+08:00 → AEDT UTC+11:00). The shared working window is 9:00 AM–2:00 PM SGT. Remember to re-check around daylight-saving transitions.
