The company is seated in Heraklion, so it resides in Greece for Article 518(1). The fact that the company itself requested service does not change the count: Article 144(2) says a service-based time limit also runs against the party at whose request service was made.

1. **The appeal period is 30 days from service.** The judgment was served on 16 July 2026. **Code of Civil Procedure (CCP), Article 518(1)** sets a 30-day appeal period for an appellant residing in Greece.

2. **The day of service is excluded.** The count begins the following day, **17 July 2026**, under **CCP Article 144(1)**. That is day 1.

3. **Count 15 days in July.** From 17 through 31 July, inclusive, 15 days elapse. The remaining 15 days do not run during August: **CCP Article 147(2)** excludes 1–31 August from the appeal period under Article 518(1).

4. **Resume counting on 1 September.** The remaining 15 days run from 1 through **15 September 2026**, inclusive. Thus the 30-day period expires on 15 September under **CCP Articles 144(1) and 147(2)**. September 15, 2026 is a Tuesday, so no extension for a non-working day applies.

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