Why people convert Dhaka to CAT time
- Scheduling a call from Dhaka to CAT: a 10:00 AM start in Dhaka lands at 6:00 AM in CAT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Dhaka and CAT are inside the 9-to-5 working day between 1:00 PM and 5:00 PM BDST time (9:00 AM–1:00 PM CAT). That is roughly 4 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Dhaka is 4:00 PM in CAT makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM BDST" is unambiguous; "3 PM" across a -4h gap is not.
- Block 1:00 PM–5:00 PM BDST as the recurring meeting window if you work primarily from Dhaka and need CAT 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.
About CAT (Central Africa Time)
Central Africa Time (CAT) is fixed at UTC+02:00 all year across a broad belt of southern and central Africa, including Zimbabwe, Zambia, Mozambique, Malawi, Rwanda, Burundi and the eastern Democratic Republic of the Congo. None of these countries observes daylight saving time, so CAT never shifts. It is the same offset as South Africa Standard Time (SAST) and the winter version of Central European Time, which makes CAT a convenient bridge between African, European and Middle Eastern schedules — Harare is level with Johannesburg all year and one hour ahead of Lagos.
Best time to call between Dhaka and CAT
Both Dhaka and CAT sit inside the 9 AM – 5 PM working day between 1:00 PM–5:00 PM BDST, which is 9:00 AM–1:00 PM CAT. That gives roughly 4 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
Dhaka and CAT overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.
Dhaka is 4 hours behind CAT (BDST UTC+06:00 → CAT UTC+02:00). The shared working window is 1:00 PM–5:00 PM BDST. Remember to re-check around daylight-saving transitions.
