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.

About East Africa Time (EAT)

East Africa Time (EAT, IANA: Africa/Nairobi, Africa/Addis_Ababa) is the civil time for East African countries, set at UTC+3:00 year-round (no DST). EAT serves approximately 320 million people across: Kenya, Tanzania, Uganda, Ethiopia, Eritrea, Djibouti, Somalia, South Sudan, Comoros, Madagascar (mainland — UTC+3), and Mayotte (French territory — UTC+3). EAT shares the same UTC offset as Moscow Standard Time (MSK), Saudi Arabian Standard Time (AST-SA), Turkey Time (TRT), and Eastern European Summer Time (EEST) — making coordination with the Middle East and Russia simple year-round. Major EAT cities: Cairo (22M metro — uses EET/CAT not EAT), Nairobi Kenya (4.4M city, 9M metro — diplomatic + UN headquarters for East Africa), Addis Ababa Ethiopia (5M city, 5.5M metro — African Union headquarters), Dar es Salaam Tanzania (5M city, 7M metro), Kampala Uganda (1.7M city, 4M metro), Mogadishu (2.6M), Khartoum (Sudan — uses CAT not EAT). Affects: Nairobi Stock Exchange (NSE) trading, Serengeti / Maasai Mara safari schedules, Kilimanjaro climbing-permit scheduling.
