- Coordinating a Seoul-based team with Athens contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

- Block 3:00 PM–5:00 PM KST as the recurring meeting window if you work primarily from Seoul and need Athens colleagues present.
