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

Facts: final judgment of the Multi-Member Court of First Instance of Heraklion, published 2 July 2026; served on the company on Thursday 16 July 2026 at the plaintiff's initiative. The company is seated in Heraklion (Greece). The remedy is an ordinary appeal (efesi) before the Court of Appeal.

Step 1 - Remedy and competent court.
The judgment is a final judgment of a first-instance court in ordinary procedure, so it is subject to appeal: art. 495 par. 1 and art. 511 KPolD (appeal lies against first-instance judgments); the appeal goes to the Court of Appeal (art. 19 KPolD).

Step 2 - Length of the time limit.
The appeal must be filed within thirty (30) days from the service of the judgment, when the party who is to appeal resides in Greece: art. 518 par. 1 KPolD (as amended by Law 4335/2015). The 60-day limit of art. 518 par. 1 applies only to a party residing abroad or of unknown residence. The company is seated in Heraklion, so the limit is 30 days.
The limit runs from service, not from publication, because the judgment was served. The three-year outer limit from publication (art. 518 par. 2 KPolD) applies only to unserved judgments and is not relevant here (publication 2 July 2026 + 3 years = 2 July 2029).

Step 3 - Starting point (dies a quo).
The day of service is not counted; the limit starts from the next day: art. 144 par. 1 KPolD in conjunction with art. 240-241 of the Civil Code (the day of the triggering event is not counted). Service on Thursday 16 July 2026, so day 1 = Friday 17 July 2026.

Step 4 - Counting the 30 days.
Days are counted continuously (art. 240 et seq. Civil Code, art. 144 KPolD). 17 July = day 1; 31 July = day 15; 15 August = day 30. The limit expires at the end of 15 August 2026 (art. 242 Civil Code: a limit counted in days ends at the end of the last day).
The Greek judicial vacation (1 July - 15 September) does not suspend or extend the time limit for filing an ordinary appeal; the limit runs through the vacation, and the court registry stays open for filing.
Check of the weekday: 16 July 2026 is a Thursday, and 30 days is 4 weeks + 2 days, so 15 August 2026 is a Saturday. 15 August is also the public holiday of the Dormition of the Theotokos.

Step 5 - Extension because the last day is a non-working day.
If the last day falls on a Saturday, a Sunday or a public holiday, the limit is extended to the end of the next working day: art. 144 par. 3 KPolD (together with art. 243 Civil Code). 15 August 2026 is both a Saturday and a holiday; Sunday 16 August 2026 is also non-working; the next working day is Monday 17 August 2026 (not a holiday).

Step 6 - Result.
The last day for filing the appeal (filing of the appeal with the registry of the Court of Appeal and, under art. 495 par. 3 and art. 518 par. 1, with the appeal then served on the opponent as required by the procedure) is Monday 17 August 2026.

RESULT: deadline = 2026-08-17; rule = art. 518 par. 1 KPolD (30 days from service) with art. 144 par. 1 and par. 3 KPolD (day of service not counted; last day Saturday/holiday 15 Aug 2026 extended to next working day)
