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 Eastern European Summer Time (EEST)
Eastern European Summer Time (EEST, IANA: Europe/Athens during DST window) is the summer-time variant of EET, set at UTC+3:00 — observed from the last Sunday of March to the last Sunday of October per EU Directive 2000/84/EC. EEST shares the same UTC offset as Moscow Standard Time (MSK), Saudi Arabia Standard Time (AST-SA), and East Africa Time (EAT). After the 2018 EU proposal to abolish twice-yearly clock changes (postponed indefinitely), the question of whether EEST countries would permanently stay on summer time (UTC+3) or revert to year-round EET (UTC+2) remains unresolved. EEST serves the same ~50 million population as EET (Greece, Cyprus, Bulgaria, Romania, Moldova, Ukraine, Lithuania, Latvia, Estonia, Finland). Affects: ASE (Athens Stock Exchange) summer trading hours, summer-festival schedules in Greek islands (Mykonos, Santorini, Ios), Finnish midsummer Juhannus celebrations, and Black Sea cruise-ship port arrival times at Constanța Romania + Varna Bulgaria + Odesa Ukraine.
