1. **The appeal period is 30 days.** The company is seated in Greece, so Article 518(1) CCP sets a 30-day appeal period from service of the judgment. Because service starts the period, the fact that the company arranged it does not prevent the period running against it: Article 144(2) CCP.

2. **The count starts on 17 July 2026.** The judgment was served on 16 July. Under Article 144(1) CCP, the day of service is excluded and counting begins the next day.

3. **August is excluded from this count.** Article 147(2) CCP provides that 1–31 August is not counted for the appeal period in Article 518(1). The 15 days from 17–31 July therefore count; the remaining 15 days run from 1–15 September.

4. **The deadline is 15 September 2026, at 7 p.m.** Article 144(1) CCP sets the deadline at 7 p.m. on the final day, extending it only if that day is legally non-working. 15 September 2026 is a Tuesday and is not a legal holiday. The judgment’s publication date does not change the calculation because the served-judgment rule applies under Article 518(1).

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