Why people convert Dhaka to Colombia time
- Scheduling a call from Dhaka to Colombia: a 10:00 AM start in Dhaka lands at 11:00 PM in Colombia the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -11h gap: Dhaka and Colombia 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 Colombia is 10:00 PM in Dhaka.
- Keeping family and friends in sync: knowing that 8:00 PM in Dhaka is 9:00 AM in Colombia makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM BDST" is unambiguous; "3 PM" across a -11h gap is not.
- With a -11h gap there is no shared 9-to-5 window, so alternate the early start: one week Dhaka takes the early slot, the next week Colombia does.
About BDST (Bangladesh Standard Time)
Bangladesh Standard Time (BDST) is the single time zone used across Bangladesh, fixed at UTC+06:00 all year. Bangladesh has not observed daylight saving time since a short-lived experiment in 2009, so the gap between Bangladesh and every other zone is constant. Dhaka, the capital, is one of the most densely populated cities in the world. Because the country sits close to the middle of the UTC+06:00 band, solar noon is near 12:00 for most of the year. BDST is listed separately from British Summer Time, which shares the BST abbreviation but is UTC+01:00.
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.
