1. **Applicable appeal period:** The company is seated in Heraklion, Greece, and the judgment was served at its opponent’s initiative. Under **Code of Civil Procedure (CPC) Article 518(1)**, the appeal period is 30 days from service.

2. **Start counting the period:** Service occurred on 16 July 2026. Under **CPC Article 144(1)**, the day of the event that starts a period is excluded. The first day is therefore **17 July**.

3. **Count the days before the August suspension:** From 17 through 31 July, 15 days elapse.

4. **Pause the count in August:** Under **CPC Article 147(2)**, procedural periods are suspended from 1 to 31 August. The count resumes on **1 September** with 15 days remaining.

5. **Find the last day:** The remaining 15 days run from 1 through **15 September 2026**. That date is a Tuesday, so the deadline is not pushed to a later working day under **CPC Article 144(1)**.

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