About CDT
Central Daylight Time (CDT) is UTC−5. It is used in Chicago, Dallas and Houston from March to November.
Central Daylight Time is UTC−5, the summer clock for Chicago, Dallas and Houston, from the second Sunday in March to the first Sunday in November. Mexico is the complication: it abolished daylight saving nationally in 2022, so Mexico City stays on UTC−6 all year and is now an hour behind Chicago for eight months of the year rather than matching it.
About BDT
Bangladesh Standard Time (BDT) is UTC+6. It is used in Bangladesh, all year.
Bangladesh Standard Time is UTC+6 with no daylight saving. It is more often written BST, which is where the trouble starts: BST also means British Summer Time at UTC+1, and the two readings are five hours apart. Converter sites split on which they answer for and rarely say. BDT is the unambiguous way to write it, and worth using in anything that matters.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on CDT switches to CST (UTC−6) from November to March. So the 11-hour figure on this page is correct for the part of the year when both places are actually on these abbreviations, and changes by an hour outside it.
BDT does not shift, so the whole change comes from one side. A recurring meeting fixed in BDT will appear to move by an hour for everyone on the other side, twice a year, without anyone changing anything.
This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.

Is BDT ahead of CDT?
BDT is 11 hours ahead of CDT.
Which time zone does this use?
CDT is UTC−5 and BDT is UTC+6. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
