BDST and CDT on the World Map
The map below highlights the BDST (Bangladesh Standard Time) and CDT (Central Daylight Time) timezone regions across the globe.
BDST – Bangladesh Standard Time
UTC+06:00Bangladesh Standard Time (BDST, UTC+06:00) is the time zone for Bangladesh, 6 hours ahead of UTC.
- •Bangladesh uses a single time zone, UTC+06:00, across the entire country.
- •Bangladesh does not observe daylight saving time, so the offset is fixed all year.
- •Dhaka is one of the most densely populated cities globally.
- •BDST is written here to distinguish it from British Summer Time (BST).
CDT – Central Daylight Time
UTC-05:00Central Daylight Time (CDT) is the daylight saving offset in the Central Time Zone, 5 hours behind UTC.
- •CDT is the same offset as EST (UTC-05:00), which can cause confusion.
- •CDT runs from the second Sunday in March to the first Sunday in November.
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.
