Frequently Asked Questions
What is the time difference between CAT and COT?
During standard time, Colombia Time is 7 hours behind Central Africa Time.
Does the Central Africa Time zone observe Daylight Saving Time?
None of the countries observing Central Africa Time use Daylight Saving Time. South Africa abolished DST in 1994, and no other CAT-observing nation currently applies seasonal clock changes — CAT remains permanently fixed at UTC+02:00 throughout the year.
Which major countries use Central Africa Time (CAT)?
Central Africa Time is observed by South Africa, Zimbabwe, Zambia, Botswana, Mozambique, Malawi, and Eswatini. South Africa is the zone's dominant economy, with Johannesburg functioning as the region's primary financial center and home to the Johannesburg Stock Exchange (JSE), Africa's largest equity market by capitalization.
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.
