Why people convert South Korea to Dhaka time
- Scheduling a call from South Korea to Dhaka: a 10:00 AM start in South Korea lands at 7:00 AM in Dhaka, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both South Korea and Dhaka 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.
- Watching a live event or market open: South Korea viewers need 6:00 AM in Dhaka to catch a 9:00 AM start there, and 3:00 AM if the event is anchored to South Korea.
- 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 South Korea and need Dhaka colleagues present.
