1. **Applicable appeal period:** The company is seated in Greece, so the appeal period is **30 days from service** of the judgment ending the proceedings: Code of Civil Procedure (CCP), **Article 518(1)**. Because the judgment was served on the company at its own initiative, the period still runs against it: **Article 144(2)**. ([Article 518](https://www.nomoskopio.gr/kpold_518.php), [Article 144](https://eur-lex.europa.eu/legal-content/EL/TXT/PDF/?uri=NIM%3A202500318))

2. **Start counting:** The service date, 16 July 2026, is excluded. The period starts the next day, **17 July**, under **Article 144(1)**. ([Article 144](https://eur-lex.europa.eu/legal-content/EL/TXT/PDF/?uri=NIM%3A202500318))

3. **Count the days and account for August:** 17–31 July accounts for **15 days**. The period is a 30-day appeal period under Article 518(1); **1–31 August is not counted** for that period under **Article 147(2)**. The remaining 15 days run from 1–15 September. ([Article 147](https://www.nomoskopio.gr/kpold_147.php))

4. **Final day:** The deadline is **15 September 2026**. It is not a statutory non-working day, so Article 144(1)’s next-working-day extension does not apply. The deadline expires at **7 p.m.** that day under the same paragraph. ([Article 144](https://eur-lex.europa.eu/legal-content/EL/TXT/PDF/?uri=NIM%3A202500318))

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