The applicable deadline is **Tuesday, 15 September 2026**.

1. The judgment was served on 16 July. Because the company is seated in Greece, the appeal period is **30 days from service** (Code of Civil Procedure, Article 518(1)). The fact that service was made at the company’s initiative does not change the count: a period triggered by service runs against the party who requested it (Article 144(2)). ([Article 518](https://www.nomoskopio.gr/kpold_518.php), [Article 144](https://www.nomoskopio.gr/kpold_144.php))

2. The service date itself is excluded. The period begins the next day, 17 July (Article 144(1)). Counting 17–31 July gives **15 days**.

3. The 30-day appeal period is one of the periods for which **1–31 August is not counted** (Article 147(2)). The remaining 15 days therefore run from 1–15 September.

4. The period expires at **7 p.m. on its last day** (Article 144(1)). Since 15 September 2026 is not a statutory holiday, no further extension applies.

RESULT: deadline = 2026-09-15; rule = Articles 518(1), 144(1)–(2), 147(2)
