Comparing Time Zones: COT and AWST

COT runs on Colombia Time (COT) at UTC-05:00. AWST runs on Australian Western Standard Time (AWST) at UTC+08:00. That puts COT 13 hours ahead of AWST — a difference of +13h at the current offsets.

In practice, when it is 9:00 AM in COT it is 10:00 PM in AWST. Midnight in COT is 1:00 PM in AWST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert COT to AWST time

Scheduling a call from COT to AWST: a 10:00 AM start in COT lands at 11:00 PM in AWST, so you can confirm the slot without doing the arithmetic yourself.
Handling a +13h gap: COT and AWST 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 AWST is 10:00 PM in COT.
Keeping family and friends in sync: knowing that 8:00 PM in COT is 9:00 AM in AWST makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM COT" is unambiguous; "3 PM" across a +13h gap is not.
With a +13h gap there is no shared 9-to-5 window, so alternate the early start: one week COT takes the early slot, the next week AWST does.

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 AWST (Australian Western Standard Time)

Australian Western Standard Time (AWST) is used in Western Australia. WA does not observe daylight saving time, having rejected it in multiple referendums. Perth is the most remote major city in the world.

Best time to call between COT and AWST

With a +13h offset there is no overlap inside a normal 9 AM – 5 PM day. AWST opens at 9:00 AM AWST, which is 10:00 PM in COT, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

COT and AWST have no shared working hours because of the +13h gap. Teams need to alternate early starts or rely on asynchronous handovers.

COT is 13 hours ahead of AWST (COT UTC-05:00 → AWST UTC+08:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
