ANSWER (from own knowledge of the Greek Code of Civil Procedure, KPolD, as in force October 2026; no sources consulted)

Step 1 - Which time limit applies.
The appeal (έφεση) against a final judgment of the Multi-Member Court of First Instance is governed by art. 518 par. 1 KPolD. The limit is thirty (30) days from service of the judgment, when the party on whom it is served resides in Greece. The company is seated in Heraklion, Crete, so it falls under the 30-day limit. The 60-day limit of art. 518 par. 1 (for a party residing abroad or of unknown residence) does not apply.

Step 2 - Does the limit run from service or from publication?
The judgment was served on the company, at the plaintiff's initiative, on Thursday 16 July 2026. Service starts the 30-day limit (art. 518 par. 1). The alternative two-year limit from publication (art. 518 par. 2) applies only if the judgment is never served. It is not relevant here, because 2 July 2028 is far later and service has taken place.

Step 3 - The starting day.
Under art. 144 par. 1 KPolD, read with arts. 240-241 Civil Code (AK), the day of the event (service) is not counted. Counting starts on the next day, Friday 17 July 2026.

Step 4 - The judicial vacation.
The civil judicial vacation runs from 1 July to 15 September (art. 144 par. 3 KPolD, together with the provisions on judicial vacations). The time limit for an ordinary appeal does not run during the vacation. It is suspended and resumes on 16 September. My count follows this suspension rule. It rests on my recollection of art. 144 par. 3 and is the least certain step.
- Days counted before the vacation: 17 July to 31 July 2026 = 15 days.
- Vacation (not counted): 1 August to 15 September 2026.
- Remaining days: 30 - 15 = 15. These run from 16 September 2026 (day 16) to 30 September 2026 (day 30).

Step 5 - End of the limit.
Under arts. 240 and 241 AK, a limit counted in days ends at the end of the last day. Day 30 is Wednesday 30 September 2026. It is a working day, neither a Saturday, a Sunday nor a public holiday, so the extension of art. 243 AK and art. 144 KPolD does not come into play.

Conclusion: the last day for filing the appeal is Wednesday 30 September 2026.

RESULT: deadline = 2026-09-30; rule = art. 518 par. 1 KPolD (30 days from service), counted per art. 144 KPolD and arts. 240-243 AK, with the judicial vacation (1 July-15 September) not counted per art. 144 par. 3 KPolD
