Why people convert Bangkok to Dhaka time
- Scheduling a call from Bangkok to Dhaka: a 10:00 AM start in Bangkok lands at 9:00 AM in Dhaka, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Bangkok and Dhaka are inside the 9-to-5 working day between 10:00 AM and 5:00 PM ICT time (9:00 AM–4:00 PM BDST). That is roughly 7 hours of usable overlap.
- Watching a live event or market open: Bangkok viewers need 8:00 AM in Dhaka to catch a 9:00 AM start there, and 1:00 AM if the event is anchored to Bangkok.
- Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a -1h gap is not.
- Block 10:00 AM–5:00 PM ICT as the recurring meeting window if you work primarily from Bangkok and need Dhaka colleagues present.
About ICT (Indochina Time)
Indochina Time (ICT) is used across Southeast Asia including Vietnam, Thailand, Laos, and Cambodia. Indonesia (Western time, WIB) also uses UTC+07:00. ICT does not observe daylight saving time.
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.
