Offset

The time difference between Hawaii Time and Central European Time is 12 hours.

12 hours

Hawaii Time (HST) is behind Central European Time (CEST).

HST: UTC-10

CEST: UTC+2

Central 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 Central European Time don't overlap on the same weekday. Central European Time is 12 hours ahead of Hawaii Time.

With some flexibility, there are two workable windows outside standard hours, depending on which side takes the early or late slot:

  • 7 AM–8 AM in Hawaii Time (7 PM–8 PM in Central European Time) — suggest 7:00 AM Hawaii Time (7:00 PM Central European Time).
  • 7 PM–8 PM in Hawaii Time (7 AM–8 AM the next day in Central European Time) — suggest 7:00 PM Hawaii Time (7:00 AM Central European Time).

Either is an early start or late finish for one side, but workable 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.
