When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Salt Lake City and Seoul don't overlap on the same weekday. Seoul is 15 hours ahead of Salt Lake City.
With some flexibility, there’s a workable window outside standard hours:
- 4 PM–8 PM in Salt Lake City (7 AM–11 AM the next day in Seoul) — suggest 6:00 PM Salt Lake City (9:00 AM Seoul).
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.
