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 Coordinated Universal Time (UTC)

Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time, defined since 1972 as the time at the Prime Meridian (0° longitude) maintained by BIPM (Bureau International des Poids et Mesures) in Sèvres, France. UTC is computed as a weighted average of approximately 400 atomic clocks at ~80 national metrology institutes (NIST in the US, NPL in UK, PTB in Germany, NICT in Japan, KRISS in Korea, etc.) per the formal definition in ITU-R Recommendation TF.460-6 (2002). UTC is functionally identical to GMT (Greenwich Mean Time) for civil purposes but differs slightly in its underlying timescale — UTC uses atomic seconds with occasional leap seconds inserted (announced by IERS Bulletin C ~6 months in advance, last leap second was December 31, 2016, and the system may be retired by 2035 per Resolution D of CGPM 2022). UTC is the standard for aviation (ICAO Annex 5), maritime navigation (IMO COLREGS), all internet protocols (NTP, PTP per IEEE 1588), all scientific publications, GPS / Galileo / GLONASS / BeiDou GNSS, and Universal Time on Wikipedia/Wikidata.
