About Hawaii Standard Time (HST)
Hawaii Standard Time (HST, IANA: Pacific/Honolulu) is the time zone for the State of Hawaii and the Aleutian Islands of Alaska west of 169.5°W. HST is UTC-10:00 year-round and does not observe Daylight Saving Time per Hawaii Revised Statutes §1-31 (Hawaii opted out of the Uniform Time Act of 1966). When the US mainland switches to Daylight Saving Time in March, the offset from Hawaii to the West Coast (Pacific Time) becomes 3 hours instead of the standard 2 hours. Honolulu sees solar noon at approximately 12:30 PM HST in summer. HST is the same offset as Cook Island Time (CKT) and Tahiti Time (TAHT) in French Polynesia, allowing easy mental conversion across the central Pacific. Time-sensitive activities affected by HST include Pacific tsunami warning system coordination per NOAA NTWC, US military operations from Joint Base Pearl Harbor-Hickam, and the Mauna Kea astronomical observatories' nightly observing schedules.
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.
