About Brasília Time (BRT)
Brasília Time (BRT, IANA: America/Sao_Paulo) is the official civil time of Brazil's most populous regions, set at UTC-3:00 — named after the federal capital city of Brasília. BRT serves approximately 175 million people across 23 of Brazil's 26 states + Federal District including the megacities São Paulo (12M), Rio de Janeiro (6.7M), Salvador (2.9M), Fortaleza (2.7M), Belo Horizonte (2.5M), Brasília (3.1M), Curitiba (1.9M). Brazil abolished Daylight Saving Time in 2019 by Presidential Decree 9772/2019 (citing minimal energy savings and disruption costs), so BRT is observed year-round without seasonal change since then. Acre State and a small portion of Amazonas use Acre Time (ACT = UTC-5:00); the remainder of Amazonas plus Mato Grosso/Mato Grosso do Sul/Rondônia use Amazon Time (AMT = UTC-4:00); the Fernando de Noronha archipelago uses UTC-2:00. BRT affects: B3 (São Paulo Stock Exchange) trading hours, Brazilian football Série A match scheduling, and Petrobras / Vale international corporate-call timing.
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.
