Why people convert Colombia to BDST time
- Scheduling a call from Colombia to BDST: a 10:00 AM start in Colombia lands at 9:00 PM in BDST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +11h gap: Colombia and BDST 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 BDST is 8:00 PM in Colombia.
- Watching a live event or market open: Colombia viewers need 8:00 PM in BDST to catch a 9:00 AM start there, and 1:00 PM if the event is anchored to Colombia.
- Always state the zone abbreviation, not just the hour. "3:00 PM COT" 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 Colombia takes the early slot, the next week BDST does.

About BDST (Bangladesh Standard Time)

BDST is listed separately from British Summer Time, which shares the BST abbreviation but is UTC+01:00.
