The appeal deadline is **Tuesday, 15 September 2026**.

1. **The appeal period is 30 days.** Because the judgment was served on the company in Greece, the domestic period under Code of Civil Procedure (CPC) **Article 518(1)** applies.
2. **Do not count the day of service.** Service was on 16 July, so counting begins on 17 July under CPC **Article 144(1)**. The 15 days from 17 through 31 July use 15 of the 30 days.
3. **Pause the count for August.** CPC **Article 147(1)** suspends the appeal period from 1 through 31 August. The count resumes on 1 September with 15 days remaining.
4. **Count the remaining days.** The 15th day is 15 September. It is a Tuesday, so no extension for a non-working final day is needed.

RESULT: deadline = 2026-09-15; rule = CPC articles 518(1), 144(1), 147(1)
