Why people convert Chicago to Dhaka time

Scheduling a call from Chicago to Dhaka: a 10:00 AM start in Chicago lands at 9:00 PM in Dhaka, so you can confirm the slot without doing the arithmetic yourself.
Handling a +11h gap: Chicago and Dhaka have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Dhaka is 8:00 PM in Chicago.
Watching a live event or market open: Chicago viewers need 8:00 PM in Dhaka to catch a 9:00 AM start there, and 1:00 PM if the event is anchored to Chicago.

Always state the zone abbreviation, not just the hour. "3:00 PM CDT" is unambiguous; "3 PM" across a +11h gap is not.
With a +11h gap there is no shared 9-to-5 window, so alternate the early start: one week Chicago takes the early slot, the next week Dhaka does.
Chicago: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +11h gap.

About CST (Central Standard Time)

Central Standard Time (CST) covers the central region of North America. It is the second most populous time zone in the US, including major cities like Chicago, Houston, and Dallas. CST is also used in Mexico City and much of Central America including Guatemala, Honduras, El Salvador, and Costa Rica. During summer, most of the US and Canada switch to Central Daylight Time (CDT, UTC-05:00), while Mexico and Central American countries generally remain on CST.

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.

Best time to call between Chicago and Dhaka

With a +11h offset there is no overlap inside a normal 9 AM – 5 PM day. Dhaka opens at 9:00 AM BDST, which is 8:00 PM in Chicago, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Chicago and Dhaka have no shared working hours because of the +11h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Chicago is 11 hours ahead of Dhaka (CDT UTC-05:00 → BDST UTC+06:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
