Why people convert Japan to Dhaka time
- Scheduling a call from Japan to Dhaka: a 10:00 AM start in Japan lands at 7:00 AM in Dhaka, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Japan and Dhaka are inside the 9-to-5 working day between 12:00 PM and 5:00 PM JST time (9:00 AM–2:00 PM BDST). That is roughly 5 hours of usable overlap.
- Coordinating a Japan-based team with Dhaka 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 JST" is unambiguous; "3 PM" across a -3h gap is not.
- Block 12:00 PM–5:00 PM JST as the recurring meeting window if you work primarily from Japan and need Dhaka colleagues present.
About JST (Japan Standard Time)
Japan Standard Time (JST) is the standard time zone for all of Japan. Japan does not observe daylight saving time. JST is 9 hours ahead of UTC and 14 hours ahead of EST. The Tokyo Stock Exchange, the world's third largest by market capitalization, operates on JST. South Korea uses the same offset (KST) but it is a distinct time zone.
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.
