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 AST (Arabia Standard Time)
Arabia Standard Time (AST) is fixed at UTC+03:00 all year across Saudi Arabia, Qatar, Kuwait, Bahrain, Iraq and Yemen. None of these countries observes daylight saving time, so the offset never changes. The abbreviation collides with Atlantic Standard Time (UTC-04:00) used in eastern Canada and the Caribbean; this page covers the Arabian peninsula meaning. Arabia Standard Time is the same offset as Moscow Standard Time and East Africa Time, which makes scheduling with Europe straightforward — Riyadh is one hour ahead of Central European Time in winter and level with it during European summer time.
