Frequently Asked

Calling Greece — Common Questions

Everything you need to know about reaching contacts in Greece.

Clocks go forward on the last Sunday of March and back on the last Sunday of October (EU rule). Local time: EET (UTC+2); EEST (UTC+3) in summer. Because its clock changes fall on different dates from the US ones (second Sunday in March, first Sunday in November), the gap to US Eastern time is not constant through the year — double-check around March–April and October–November.

Greek business contacts respond well to warmth and familiarity — a local number is a small but meaningful step toward that trust.
