Understanding the -4h Gap: AEDT vs Indonesia
AEDT runs on Australian Eastern Daylight Time (AEDT) at UTC+11:00. Indonesia runs on Western Indonesia Time (WIB) at UTC+07:00. That puts AEDT 4 hours behind Indonesia — a difference of -4h at the current offsets.
In practice, when it is 9:00 AM in AEDT it is 5:00 AM in Indonesia. Midnight in AEDT is 8:00 PM in Indonesia. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert AEDT to Indonesia time
- Scheduling a call from AEDT to Indonesia: a 10:00 AM start in AEDT lands at 6:00 AM in Indonesia, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both AEDT and Indonesia are inside the 9-to-5 working day between 1:00 PM and 5:00 PM AEDT time (9:00 AM–1:00 PM WIB). That is roughly 4 hours of usable overlap.
- Coordinating a AEDT-based team with Indonesia contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM AEDT" is unambiguous; "3 PM" across a -4h gap is not.
- Block 1:00 PM–5:00 PM AEDT as the recurring meeting window if you work primarily from AEDT and need Indonesia 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 WIB (Western Indonesia Time)
Western Indonesia Time (WIB, Waktu Indonesia Barat) is one of Indonesia's three time zones, fixed at UTC+07:00 all year. It covers Java, Sumatra, West Kalimantan and the provinces around them — home to Jakarta, the country's capital and largest city, plus Surabaya and Bandung. Indonesia does not observe daylight saving time, so WIB never shifts. WIB shares its UTC+07:00 offset with Indochina Time (ICT) and Christmas Island Time, but is a distinct zone covering the western half of the Indonesian archipelago. The country's other zones are WITA (UTC+08:00) in the centre and WIT (UTC+09:00) in the east.
Best time to call between AEDT and Indonesia
Both AEDT and Indonesia sit inside the 9 AM – 5 PM working day between 1:00 PM–5:00 PM AEDT, which is 9:00 AM–1:00 PM WIB. That gives roughly 4 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
AEDT and Indonesia overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.
AEDT is 4 hours behind Indonesia (AEDT UTC+11:00 → WIB UTC+07:00). The shared working window is 1:00 PM–5:00 PM AEDT. Remember to re-check around daylight-saving transitions.
