Why people convert EEST to Honolulu time
- Scheduling a call from EEST to Honolulu: a 10:00 AM start in EEST lands at 9:00 PM in Honolulu the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -13h gap: EEST and Honolulu have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Honolulu is 8:00 PM in EEST.
- Watching a live event or market open: EEST viewers need 8:00 PM in Honolulu to catch a 9:00 AM start there, and 1:00 PM if the event is anchored to EEST.
- Always state the zone abbreviation, not just the hour. "3:00 PM EEST" is unambiguous; "3 PM" across a -13h gap is not.
- With a -13h gap there is no shared 9-to-5 window, so alternate the early start: one week EEST takes the early slot, the next week Honolulu does.
About EEST (Eastern European Summer Time)

It runs from the last Sunday in March to the last Sunday in October, in step with the rest of the European Union. EEST covers Greece, Finland, Romania, Bulgaria, the Baltic states, Ukraine and Moldova, and matches the offset used year-round by Moscow, Istanbul and Riyadh during those months. Athens and Helsinki both sit near the western edge of the EEST band, so summer evenings stay light well past 21:00.
About HST (Hawaii Standard Time)
Hawaii Standard Time (HST) is used in the state of Hawaii and does not observe daylight saving time. This makes HST one of the most consistent time zones in the US. The Hawaiian Islands are among the last places on Earth to see a new calendar day.
