Why people convert Colombia to AEDT time
- Scheduling a call from Colombia to AEDT: a 10:00 AM start in Colombia lands at 2:00 AM in AEDT the next day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +16h gap: Colombia and AEDT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in AEDT is 1:00 AM in Colombia.
- Watching a live event or market open: Colombia viewers need 1:00 AM in AEDT to catch a 9:00 AM start there, and 8:00 AM if the event is anchored to Colombia.
- Always state the zone abbreviation, not just the hour. "3:00 PM COT" is unambiguous; "3 PM" across a +16h gap is not.
- With a +16h gap there is no shared 9-to-5 window, so alternate the early start: one week Colombia takes the early slot, the next week AEDT does.
About COT (Colombia Time)
Colombia Time (COT) is used throughout Colombia. Colombia does not observe daylight saving time. COT shares the same offset as EST (UTC-05:00). Bogotá, the capital, is one of the largest cities in South America.
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 Colombia and AEDT

Business hours overlap
Colombia and AEDT have no shared working hours because of the +16h gap. Teams need to alternate early starts or rely on asynchronous handovers.
Colombia is 16 hours ahead of AEDT (COT UTC-05:00 → AEDT UTC+11:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
