About JST

Japan Standard Time (JST) is UTC+9. It is used in all of Japan, with no daylight saving.

Japan Standard Time is UTC+9 for the whole country and has had no daylight saving since 1951, when the occupation-era experiment was abandoned. Proposals to reintroduce it, most recently before the 2020 Olympics, have failed each time. The offset is shared with South Korea, so Tokyo and Seoul never differ by even a minute.

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?

Neither JST nor BDT shifts with the seasons, so this 3-hour difference holds all year. That is unusual enough to be worth relying on: most cross-continental gaps move twice a year.

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.
