Why people convert Seoul to Bangladesh time
- Scheduling a call from Seoul to Bangladesh: a 10:00 AM start in Seoul lands at 7:00 AM in Bangladesh, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Seoul and Bangladesh are inside the 9-to-5 working day between 12:00 PM and 5:00 PM KST time (9:00 AM–2:00 PM BDST). That is roughly 5 hours of usable overlap.
- Coordinating a Seoul-based team with Bangladesh contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM KST" is unambiguous; "3 PM" across a -3h gap is not.
- Block 12:00 PM–5:00 PM KST as the recurring meeting window if you work primarily from Seoul and need Bangladesh colleagues present.

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.
