About Bangladesh Standard Time (BST)
Bangladesh Standard Time (BST, IANA: Asia/Dhaka) is the civil time of the People's Republic of Bangladesh, set at UTC+6:00 year-round. Bangladesh introduced Daylight Saving Time in 2009 (clocks advanced one hour) but abolished it later in 2009 after public confusion + religious-prayer-time complications. BST is identical in offset to Bhutan Time (BTT), Kyrgyzstan Time (KGT), Omsk Time (Russian Federation Yekaterinburg region), and Vostok Antarctica Time — facilitating cross-Central-Asia + South-Asia coordination. The 'BST' abbreviation is ambiguous globally — it also stands for British Summer Time (UTC+1), so in international aviation/business contexts the IANA identifier 'Asia/Dhaka' is preferred. BST serves approximately 170 million Bangladeshi people across 8 divisions + 64 districts. Major cities: Dhaka (10M city, 22M metro — the world's 4th most populous city after Tokyo/Delhi/Shanghai), Chittagong (2.6M city, 5.5M metro — main seaport on the Bay of Bengal), Khulna (660K), Rajshahi (450K), Sylhet (480K), Barisal (330K), Rangpur (340K), Mymensingh (260K). Affects: Dhaka Stock Exchange (DSE) trading hours, garment-industry shift scheduling (textile manufacturing is Bangladesh's largest export industry).
About Atlantic Standard Time (AST)
Atlantic Standard Time (AST, IANA: America/Halifax, America/Puerto_Rico) is the time zone for the Canadian Maritime provinces and most of the Caribbean, set at UTC-4:00. AST is observed in: Nova Scotia, New Brunswick, Prince Edward Island, Labrador (partially), Newfoundland's Labrador portion, eastern Quebec, Puerto Rico, US Virgin Islands, Bermuda, Anguilla, Antigua, Aruba, Barbados, British Virgin Islands, Curaçao, Dominica, Grenada, Guadeloupe, Martinique, Saint Lucia, Saint Vincent, Trinidad and Tobago, and Venezuela (since 2007). Canadian Maritime provinces observe AST in winter and switch to ADT = UTC-3:00 in summer per the Energy Policy Act-aligned Canadian schedule. The Caribbean territories (Puerto Rico, USVI, Bermuda) and US territories observe AST year-round without DST per their territorial governments. AST is the same offset as EDT (Eastern Daylight Time) during US summer months, so Halifax and New York are on the same clock in summer but Halifax is one hour ahead in winter.
