COT — Colombia Time
See what COT means, where it is used, its UTC-5 offset, and how to compare or convert it to other time zones.
Meaning and usage areas
COT stands for Colombia Time and uses UTC-5. It is observed in Colombia as the standard civil time throughout the year.
No daylight saving changes
COT does not observe daylight saving time, so the offset remains UTC-5 year-round. Clocks do not shift seasonally.
Convert across time zones
Compare COT with other zones using the hour-by-hour grid and time difference tables. Export meetings with ICS download or send to Google Calendar and Gmail.
How to Convert COT to Other Time Zones
Open the COT converter page: Go to https://www.xconvert.com/time-converter/cot-time-zone to open the visual comparison grid with COT (Colombia Time) already loaded. This page is useful when you need to line up work hours for a client call, compare support coverage, or schedule a remote meeting across teams that operate on UTC-5.
Add comparison time zones or cities: Click “+ Add City” and search for the locations or time zones you want to compare against COT. A practical setup is to add teams, customers, or vendors you work with, then compare their rows against COT to find overlap with the green work-hour blocks and avoid yellow evening or gray night periods.
Select a meeting window on the grid: Click “Select” to enter selection mode, then drag across the COT row to highlight a time range in purple. You can drag the center of the selection to move it or use the left and right handles to resize it, which is helpful when you are testing whether a support handoff, sales call, or interview slot fits cleanly into another region’s local day.
Export and share the result: Once a range is selected, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This makes it easy to send a confirmed time block to a distributed team so each person sees the meeting in their own local time without manual conversion.
About Colombia Time (COT)
COT stands for Colombia Time. Its standard offset is UTC-5, which means local time in COT is five hours behind Coordinated Universal Time.
COT does not observe DST and has no counterpart. That makes it a stable reference throughout the year because the offset remains UTC-5 in every month rather than shifting seasonally.
COT shares the same UTC-5 offset with several other abbreviations, including ACT, CDT, CIST, CST, CT, EASST, ECT, EST, ET, PET, and R. Even when the offset matches, the abbreviation in use can differ by region or context, so using a visual converter helps prevent confusion when coordinating calendars.
COT and Daylight Saving Time
COT does not observe daylight saving time. There is no seasonal switch, no summer offset, and no winter counterpart, so the time stays fixed at UTC-5 all year.
Because COT does not change, there are no DST transition dates to track in the current year. This is especially useful for recurring meetings, payroll cutoffs, shift planning, and customer support schedules because the COT side of the schedule remains constant even if another location changes its clocks.

Is COT the same as EST or ET?
COT shares the same UTC-5 offset as EST and ET in some contexts, along with ACT, CDT, CIST, CST, CT, EASST, ECT, PET, and R. However, matching offsets do not always mean the abbreviations are interchangeable, so it is still best to compare the actual time rows visually before sending invitations.
