COT and UTC on the World Map
The map below highlights the COT (Colombia Time) and UTC (Coordinated Universal Time) timezone regions across the globe.
COT – Colombia Time
UTC-05:00Colombia Time (COT) is the standard time for Colombia, 5 hours behind UTC.
- •Colombia does not observe daylight saving time.
- •COT is the same offset as EST (UTC-05:00).
- •Bogotá sits at 2,640m elevation, making it one of the highest capital cities.
UTC – Coordinated Universal Time
UTC+00:00Coordinated Universal Time (UTC) is the world's primary time standard, used as the basis for civil time worldwide.
- •UTC is the basis for all civil time zones worldwide.
- •The abbreviation 'UTC' is a compromise between English (CUT) and French (TUC).
- •UTC is based on atomic clocks and is accurate to within a nanosecond per day.
- •Servers and databases worldwide store timestamps in UTC to avoid timezone confusion.
- •Leap seconds are occasionally added to UTC to keep it aligned with Earth's rotation.
COT vs UTC: Offsets, DST and Best Call Times
COT runs on Colombia Time (COT) at UTC-05:00. UTC runs on Coordinated Universal Time (UTC) at UTC+00:00. That puts COT 5 hours ahead of UTC — a difference of +5h at the current offsets.
In practice, when it is 9:00 AM in COT it is 2:00 PM in UTC. Midnight in COT is 5:00 AM in UTC. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert COT to UTC time
- Scheduling a call from COT to UTC: a 10:00 AM start in COT lands at 3:00 PM in UTC, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both COT and UTC are inside the 9-to-5 working day between 9:00 AM and 12:00 PM COT time (2:00 PM–5:00 PM UTC). That is roughly 3 hours of usable overlap.
- Watching a live event or market open: COT viewers need 2:00 PM in UTC to catch a 9:00 AM start there, and 7:00 PM if the event is anchored to COT.
- Always state the zone abbreviation, not just the hour. "3:00 PM COT" is unambiguous; "3 PM" across a +5h gap is not.
- Block 9:00 AM–12:00 PM COT as the recurring meeting window if you work primarily from COT and need UTC colleagues present.
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 UTC (Coordinated Universal Time)
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is effectively the successor to GMT and is based on International Atomic Time with leap seconds added to keep it synchronized with Earth's rotation. UTC is used in aviation, computing, navigation, weather forecasting, and the International Space Station. Most programming languages and databases store timestamps in UTC.
Best time to call between COT and UTC
Both COT and UTC sit inside the 9 AM – 5 PM working day between 9:00 AM–12:00 PM COT, which is 2:00 PM–5:00 PM UTC. That gives roughly 3 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
COT and UTC overlap for about 3 hours during the working day — enough for meetings if you avoid the edges of the window.
COT is 5 hours ahead of UTC (COT UTC-05:00 → UTC UTC+00:00). The shared working window is 9:00 AM–12:00 PM COT. Remember to re-check around daylight-saving transitions.
