Assuming the appeal is filed under the rules applicable to appeals lodged from 1 January 2026, the last day is **15 September 2026**. The 2025 amendment applies to appeals lodged from that date. ([Law 5221/2025, art. 126(4)](https://portal.culture.gov.gr/wp-content/uploads/2025/07/fek_a_133_2025.pdf))

1. **Applicable appeal period:** Because the company is seated in Greece and the judgment was served, the appeal period is 30 days from service. **Code of Civil Procedure (CCP), art. 518(1).** ([Law 5221/2025, art. 43](https://portal.culture.gov.gr/wp-content/uploads/2025/07/fek_a_133_2025.pdf))

2. **Start of count:** The service date, 16 July, is excluded. The count starts the next day, **17 July**. **CCP, art. 144(1).** ([CCP, art. 144](https://www.nomoskopio.gr/kpold_144.php))

3. **Count before the August pause:** 17–31 July counts as 15 days.

4. **August pause:** 1–31 August is excluded from the appeal period. **CCP, art. 147(2).** ([CCP, art. 147](https://www.nomoskopio.gr/kpold_147.php))

5. **Count after the pause:** The count resumes on 1 September. The remaining 15 days run through **15 September**, the 30th counted day.

6. **Deadline:** The period expires at 7 p.m. on its last day under **CCP, art. 144(1)**. 15 September 2026 is a Tuesday, so no next-working-day extension applies.
