1. Because the judgment was served, the appeal period runs from service. For an appellant residing in Greece, Article 518(1) CCP sets a **30-day** period. The company’s seat is in Heraklion, so the domestic period applies. ([Article 518(1)](https://www.nomoskopio.gr/kpold_518.php))

2. The period starts on the day after service: service was Thursday **16 July 2026**, so **Friday 17 July** is day 1 (Article 144(1) CCP).

3. Counting 30 calendar days, including weekends: 17–31 July is 15 days; 1–15 August is the next 15. Day 30 therefore falls on **Saturday 15 August 2026**.

4. A Saturday is an excluded and non-working day, and a period ending on an excluded day expires at 7 p.m. on the next non-excluded day (Article 144(1), (3) CCP). Sunday 16 August is also excluded, so the next non-excluded day is **Monday 17 August 2026**. The deadline is 7 p.m. that day.

RESULT: deadline = 2026-08-17; rule = Article 518(1) CCP
