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

1. The judgment was served on the company on **16 July 2026**. Because the company is seated in Greece, service of the final judgment triggered the **30-day** appeal period. **Greek Code of Civil Procedure (CPC), article 518(1).** The earlier publication date does not start the count where the judgment has been served. [Official Gazette, Law 5221/2025, article 43](https://api.et.gr/apiLAW/1/2025/5221/pdf)

2. The day of service is excluded. **17 July** is day 1. **CPC article 144(1).** [Piraeus Court of Appeal, decision 128/2022, applying article 144(1)](https://www.efeteio-peir.gr/?p=9232)

3. **17–31 July** accounts for **15 days**. **1–31 August** accounts for **zero**, because August is excluded from the article 518(1) period. **CPC article 147(2).** [Official Gazette, Law 5282/2026, article 15](https://www.aade.gr/sites/default/files/2026-05/fek_a_30-2026%20_.%205282-2026.pdf)

4. The count resumes on **1 September**. **1–15 September** supplies the remaining **15 days**, making **15 September** day 30. It was a Tuesday, so the last-day extension for an excluded day does not apply. **CPC articles 147(2) and 144(1).** [Official Gazette, Law 5282/2026, article 15](https://www.aade.gr/sites/default/files/2026-05/fek_a_30-2026%20_.%205282-2026.pdf); [Piraeus Court of Appeal, decision 128/2022](https://www.efeteio-peir.gr/?p=9232)

RESULT: deadline = 2026-09-15; rule = Greek CPC articles 518(1), 144(1), and 147(2)
