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

1. **Applicable period:** Because the judgment was served and the company is seated in Greece, the appeal period is **30 days from service** under Article 518(1) of the Greek Code of Civil Procedure. The publication date does not start the period in this served-judgment case.
2. **First day:** Service was on Thursday, 16 July. The day of service is excluded, so counting begins on **17 July** under Article 144(1).
3. **July count:** **17–31 July = 15 days**. Under Article 147(2), **1–31 August is not counted** toward the Article 518(1) appeal period.
4. **Remaining days:** The remaining **15 days** run from **1–15 September**. Day 30 is therefore **15 September**.

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