Frequently Asked Questions
What is the time difference between HST and COT?
During standard time, Colombia Time is 5 hours ahead of Hawaii-Aleutian Standard Time.
Does Hawaii observe Daylight Saving Time?
Hawaii does not observe Daylight Saving Time and has not done so since 1947, remaining fixed at UTC-10:00 year-round. At roughly 20° North latitude, Hawaii's daylight hours vary by only about 1.5 hours between the summer and winter solstices — far too little to justify the disruption of a seasonal clock change.
Why is it called Hawaii-Aleutian time?
The name combines two geographically distant US territories that share the same UTC-10:00 standard offset: the Hawaiian Islands in the central Pacific and the westernmost Aleutian Islands of Alaska, which extend past the 180° meridian into the Eastern Hemisphere. Despite sharing a base offset, they behave differently — Hawaii observes no DST, while the Aleutian communities such as Adak do advance to HDT (UTC-9) each summer.
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.
