Frequently Asked Questions
What is the time difference between AEDT and COT?
During standard time, Colombia Time is 16 hours behind Australian Eastern Daylight Time.
When does AEDT start and end?
AEDT begins on the first Sunday in October at 02:00 local time, when clocks spring forward one hour from AEST (UTC+10) to AEDT (UTC+11). It ends on the first Sunday in April at 03:00 local time, when clocks fall back to AEST. In 2026, AEDT starts on October 4 and ends on April 5 — following the Southern Hemisphere summer calendar, which runs opposite to DST schedules in Europe and North America.
Is Brisbane on AEDT?
No — Queensland, including Brisbane, does not observe Daylight Saving Time and remains on AEST (UTC+10) year-round. During the AEDT period from October through April, Sydney and Melbourne advance to UTC+11 while Brisbane stays at UTC+10, creating a one-hour gap between cities that share nearly the same longitude and are otherwise in the same time zone for the other six months of the year.
Does Colombia observe Daylight Saving Time?
Colombia does not observe Daylight Saving Time and has no current plans to do so. COT remains fixed at UTC-05:00 every day of the year, providing a consistent, unchanging reference point for international business and logistics.
How does Colombia Time (COT) align with the US?
COT (UTC-05:00) matches US Eastern Standard Time (EST) exactly during the Northern Hemisphere winter, creating zero offset between Bogotá and New York. During US Daylight Saving Time in summer, COT runs one hour behind Eastern Daylight Time (EDT, UTC-04:00), maintaining a gap narrow enough that a full shared workday remains easily achievable — one of the tightest nearshore alignments available from South America.
