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.
About GST
Gulf Standard Time (GST) is UTC+4. It is used in Dubai, Abu Dhabi and Muscat.
Gulf Standard Time is UTC+4, covering the United Arab Emirates and Oman, and there is no daylight saving anywhere on the Arabian peninsula. The scheduling complication in the region is not the clock but the week: the UAE moved its weekend to Saturday–Sunday in 2022, while Saudi Arabia and several neighbours keep Friday–Saturday, so a Thursday afternoon meeting lands differently across a border that has no time difference at all.
Does this gap change with the seasons?
Neither BDT nor GST shifts with the seasons, so this 2-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.
