Why people convert Doha to COT time
- Scheduling a call from Doha to COT: a 10:00 AM start in Doha lands at 2:00 AM in COT, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -8h gap: Doha and COT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in COT is 1:00 AM in Doha.
- Watching a live event or market open: Doha viewers need 1:00 AM in COT to catch a 9:00 AM start there, and 8:00 AM if the event is anchored to Doha.
- Always state the zone abbreviation, not just the hour. "3:00 PM AST" is unambiguous; "3 PM" across a -8h gap is not.
- With a -8h gap there is no shared 9-to-5 window, so alternate the early start: one week Doha takes the early slot, the next week COT does.

The abbreviation collides with Atlantic Standard Time (UTC-04:00) used in eastern Canada and the Caribbean; this page covers the Arabian peninsula meaning. Arabia Standard Time is the same offset as Moscow Standard Time and East Africa Time, which makes scheduling with Europe straightforward — Riyadh is one hour ahead of Central European Time in winter and level with it during European summer time.
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.
