1. Under **Article 518(1) CPC**, an appeal must be filed within 30 days after service of the judgment when the appellant is in Greece. The company is seated in Heraklion, and service was on 16 July 2026.

2. Under **Article 144(1) CPC**, the triggering day is excluded, so the count begins on 17 July. From 17 through 31 July, 15 days run.

3. Under **Article 147(1) CPC**, the appeal period is suspended from 1 through 31 August. The count resumes on 1 September with 15 days remaining.

4. The 15th remaining day is **15 September 2026**. It is a Tuesday, so the next-working-day rule in **Article 144(2) CPC** does not extend the deadline.

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