Why people convert Oslo to Dhaka time
- Scheduling a call from Oslo to Dhaka: a 10:00 AM start in Oslo lands at 2:00 PM in Dhaka, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Oslo and Dhaka are inside the 9-to-5 working day between 9:00 AM and 1:00 PM CEST time (1:00 PM–5:00 PM BDST). That is roughly 4 hours of usable overlap.
- Booking travel or deliveries: tracking Dhaka local time against Oslo keeps pickup windows and arrival estimates honest across the +4h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM CEST" is unambiguous; "3 PM" across a +4h gap is not.
- Block 9:00 AM–1:00 PM CEST as the recurring meeting window if you work primarily from Oslo and need Dhaka colleagues present.
- Oslo: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +4h gap.
About CET (Central European Time)
Central European Time (CET) is the standard time zone for most of Europe, covering over 30 countries from Spain to Poland, and from Norway to Italy. CET is 1 hour ahead of GMT and is used by the European Union's most populous nations. During summer, most CET countries switch to Central European Summer Time (CEST, UTC+02:00). Major European financial markets in Frankfurt, Paris, and Amsterdam operate on CET.
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.

Business hours overlap
Oslo and Dhaka overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.
Oslo is 4 hours ahead of Dhaka (CEST UTC+02:00 → BDST UTC+06:00). The shared working window is 9:00 AM–1:00 PM CEST. Remember to re-check around daylight-saving transitions.
