Why people convert Thailand to AEDT time
- Scheduling a call from Thailand to AEDT: a 10:00 AM start in Thailand lands at 2:00 PM in AEDT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Thailand and AEDT are inside the 9-to-5 working day between 9:00 AM and 1:00 PM ICT time (1:00 PM–5:00 PM AEDT). That is roughly 4 hours of usable overlap.
- Watching a live event or market open: Thailand viewers need 1:00 PM in AEDT to catch a 9:00 AM start there, and 8:00 PM if the event is anchored to Thailand.
- Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a +4h gap is not.
- Block 9:00 AM–1:00 PM ICT as the recurring meeting window if you work primarily from Thailand and need AEDT colleagues present.
About ICT (Indochina Time)
Indochina Time (ICT) is used across Southeast Asia including Vietnam, Thailand, Laos, and Cambodia. Indonesia (Western time, WIB) also uses UTC+07:00. ICT does not observe daylight saving time.
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 Thailand and AEDT
Both Thailand and AEDT sit inside the 9 AM – 5 PM working day between 9:00 AM–1:00 PM ICT, which is 1:00 PM–5:00 PM AEDT. That gives roughly 4 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
Thailand and AEDT overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.
Thailand is 4 hours ahead of AEDT (ICT UTC+07:00 → AEDT UTC+11:00). The shared working window is 9:00 AM–1:00 PM ICT. Remember to re-check around daylight-saving transitions.
