Frequently Asked Questions
What is the time difference between COT and NZST?
During standard time, New Zealand Standard Time is 17 hours ahead of Colombia Time.
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.
Does New Zealand observe Daylight Saving Time?
New Zealand observes Daylight Saving Time annually, advancing clocks to New Zealand Daylight Time (NZDT) at UTC+13:00 on the last Sunday of September and returning to NZST (UTC+12:00) on the first Sunday of April. In 2026, clocks spring forward on September 27 and fall back on April 5 — following the Southern Hemisphere calendar, which runs opposite to DST schedules in Europe and North America.
Why does Antarctica use New Zealand Time?
McMurdo Station and Amundsen-Scott South Pole Station — the two largest US Antarctic research bases — operate on NZST and NZDT because their primary supply and personnel flights operate out of Christchurch International Airport in New Zealand. Aligning base operations with New Zealand time eliminates scheduling complexity across the Christchurch–McMurdo logistics chain, which handles all cargo, fuel, and personnel rotations for the US Antarctic Program.
