About CEST
Central European Summer Time (CEST) is UTC+2. It is used in Paris, Berlin, Madrid and Rome from late March to late October.
Central European Summer Time is UTC+2, in force from the last Sunday in March to the last Sunday in October. The European changeover happens at 01:00 UTC everywhere simultaneously, unlike the US which changes at 2am local time in each zone — so Europe's internal offsets never break during the transition, while North America's briefly do.
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 CEST switches to CET (UTC+1) from late October to late March. So the 4-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.
Frequently asked questions
What time is 9:00 AM CEST in BDT?

Is BDT ahead of CEST?
BDT is 4 hours ahead of CEST.
Which time zone does this use?
CEST is UTC+2 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.
