ANSWER (Greek Code of Civil Procedure, KPolD, as in force October 2026)

Step 1 - Which time limit applies.
The judgment of the Multi-Member Court of First Instance (ordinary procedure) is a final judgment, so an appeal (efesi) lies against it (art. 511 KPolD). The limit is set by art. 518 par. 1 KPolD: the appeal must be filed within thirty (30) days from service of the judgment, if it was served at the initiative of a party. The company is seated in Heraklion, so it resides in Greece; the 60-day limit of art. 518 par. 1 for parties residing abroad or of unknown residence does not apply.

Step 2 - Which of the two alternative limits is relevant.
Art. 518 par. 2 KPolD (two years from publication of the judgment, if it was not served) is only a long-stop for unserved judgments. Here the judgment was served on 16 July 2026, so the 30-day limit from service under art. 518 par. 1 governs. (The two-year limit would end on 2 July 2028 and is irrelevant.)

Step 3 - Starting event and first day.
The event that starts the limit is service on Thursday 16 July 2026 (art. 518 par. 1 KPolD). Limits under KPolD are counted by the Civil Code rules (art. 144 par. 1 KPolD, referring to arts. 240-247 Civil Code). Under art. 241 Civil Code the day of the starting event is not counted, so day 1 is Friday 17 July 2026.

Step 4 - Counting 30 days.
17 July = day 1; 31 July = day 15; 1 August = day 16; 15 August = day 30. Under art. 242 Civil Code a limit set in days ends at the end of the last day. The raw expiry is therefore Saturday 15 August 2026.

Step 5 - Saturday / public holiday extension.
15 August is a Saturday and also a public holiday (Dormition of the Theotokos). Under art. 144 par. 1 KPolD together with art. 243 Civil Code, if the last day of the limit is a Sunday, a public holiday or a Saturday, the limit is extended to the end of the next working day. Sunday 16 August is not a working day either. The next working day is Monday 17 August 2026, which is not a holiday.

Step 6 - Judicial vacation.
Under the current text of the code the July-September judicial vacation does not suspend the 30-day limit for the appeal, and no further extension applies. The limit stays as computed.

Conclusion: the last day for filing the appeal is Monday 17 August 2026 (end of the day).

RESULT: deadline = 2026-08-17; rule = art. 518 par. 1 KPolD (30 days from service), counted under art. 144 par. 1 KPolD with arts. 240-243 Civil Code (art. 241 start day excluded; art. 243 Saturday/holiday extension to next working day)
