The company is seated in Heraklion, so the 30-day appeal period applies.

1. **Applicable period:** An appeal must be filed within 30 days of service when the appellant is in Greece: Code of Civil Procedure (ΚΠολΔ) **Article 518(1)**.
2. **First day of the count:** The day of service is not counted; the period begins the following day. Service was Thursday 16 July 2026, so day 1 is Friday 17 July: **Article 144(1)**.
3. **August is counted:** The August suspension does not apply to the appeal period under Article 518: **Article 147(2)**.
4. **Thirtieth day:** Counting 17–31 July gives 15 days; 1–15 August gives the remaining 15. The thirtieth day is Saturday 15 August 2026.
5. **Weekend/holiday adjustment:** Since the last day falls on a non-working day, the period expires on the next working day: **Article 144(1)**. Both Sunday 16 August and Saturday 15 August are non-working days, so the next working day is Monday 17 August 2026.

RESULT: deadline = 2026-08-17; rule = Article 518(1) and Articles 144(1), 147(2)
