The **last day to file the appeal is Tuesday, 15 September 2026**.

1. Because the company is seated in Greece and the judgment was served, the appeal period is **30 days from service** under Article 518(1) of the Greek Code of Civil Procedure. The publication date does not set the deadline here; Article 518(2) applies when the judgment has not been served.
2. Service took place on Thursday, 16 July. The service day is excluded, so counting starts on **Friday, 17 July** under Article 144(1).
3. **17–31 July** supplies 15 days. **1–31 August** is excluded from the Article 518(1) period under Article 147(2).
4. The remaining 15 days run from **1–15 September**. Day 30 is **15 September** (Articles 518(1) and 147(2)).

RESULT: deadline = 2026-09-15; rule = Article 518(1), read with Articles 144(1) and 147(2) of the Greek Code of Civil Procedure
