Understanding the -11h Gap: BDST vs CDT

BDST runs on Bangladesh Standard Time (BDST) at UTC+06:00. CDT runs on Central Daylight Time (CDT) at UTC-05:00. That puts BDST 11 hours behind CDT — a difference of -11h at the current offsets.

In practice, when it is 9:00 AM in BDST it is 10:00 PM in CDT on the previous day. Midnight in BDST is 1:00 PM in CDT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert BDST to CDT time

Scheduling a call from BDST to CDT: a 10:00 AM start in BDST lands at 11:00 PM in CDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -11h gap: BDST and CDT 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 CDT is 10:00 PM in BDST.
Coordinating a BDST-based team with CDT 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 BDST" 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 BDST takes the early slot, the next week CDT does.

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 CDT (Central Daylight Time)

Central Daylight Time (CDT) is observed during summer months in the US and Canadian portions of the Central Time Zone. Clocks are moved forward by one hour, aligning with Eastern Standard Time (EST). Most of Mexico and Central America do not observe CDT, staying on CST year-round.

Best time to call between BDST and CDT

With a -11h offset there is no overlap inside a normal 9 AM – 5 PM day. CDT opens at 9:00 AM CDT, which is 10:00 PM in BDST, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

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

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