Offset

HST: UTC-10
EEST: UTC+3
Eastern European Time is currently observing daylight saving time; Hawaii Time is not.
When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Hawaii Time and Eastern European Time don't overlap on the same weekday. Eastern European Time is 13 hours ahead of Hawaii Time.
With some flexibility, there’s a workable window outside standard hours:
- 6 PM–8 PM in Hawaii Time (7 AM–9 AM the next day in Eastern European Time) — suggest 7:00 PM Hawaii Time (8:00 AM Eastern European Time).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
This window may shift by an hour during daylight saving time.
Public holidays in 2026
National public holidays can affect availability — a counterpart is likely off work on their own holidays, so it's worth planning meetings and deadlines around them.
