1. **The 30-day appeal period applies.** The company is seated in Heraklion, Greece, so the period is 30 days under **Article 518(1) CCP**. Service started that period even though it was made at the company’s own initiative: **Article 144(2) CCP** says a period beginning with service runs against the person who requested the service. ([Article 518](https://www.nomoskopio.gr/kpold_518.php); [Article 144](https://www.nomoskopio.gr/kpold_144.php))

2. **Start counting on 17 July 2026.** The service date, 16 July, is not counted; the period begins the next day under **Article 144(1) CCP**.

3. **Count 15 days from 17–31 July.** That leaves 15 days of the 30-day period.

4. **Do not count 1–31 August.** August is excluded from the appeal period under **Article 147(2) CCP**, which expressly includes the period under Article 518(1). ([Article 147](https://www.nomoskopio.gr/kpold_147.php))

5. **Count the remaining 15 days from 1–15 September.** The thirtieth day is Tuesday, 15 September 2026. It is not a Saturday or other legally excluded day, so the deadline does not roll forward under **Article 144(1) and (3) CCP**.

RESULT: deadline = 2026-09-15; rule = Articles 518(1), 144(1)-(3), 147(2) CCP
