ANSWER (from own knowledge of the Greek Code of Civil Procedure, KPolD; no sources consulted)

Step 1 - Which time limit applies.
An appeal (efesi) against a final first-instance judgment must be filed within 30 days from service of the judgment when the party lives in Greece (60 days if the party lives abroad or its residence is unknown). Rule: Art. 518 para. 1 KPolD. The company is seated in Heraklion, so the limit is 30 days.

Step 2 - Does the service trigger the 30 days?
Yes. The judgment was served on the company on Thursday 16 July 2026, at the plaintiff's initiative. Because the judgment was served, the 30-day period of Art. 518 para. 1 applies. The alternative limit of Art. 518 para. 2 KPolD (three years from publication of the judgment, if it is never served) does not apply. The publication date of 2 July 2026 is irrelevant here.

Step 3 - Starting point.
A period counted in days does not include the day of the event that triggers it, so the day of service (16 July) is not counted. The period starts on the following day, Friday 17 July 2026 (day 1). Rule: Art. 144 para. 1 KPolD, with the general computation rules of Arts. 144-146 KPolD and Art. 241 of the Civil Code (the Civil Code rules on periods apply).

Step 4 - Counting 30 days.
- Day 1 = 17 July 2026 (Friday).
- 17 to 31 July is 15 days, so day 15 = 31 July.
- 1 to 15 August is a further 15 days, so day 30 = 15 August 2026.
The nominal last day of the period is therefore Saturday 15 August 2026.

Step 5 - Judicial vacation.
Under the current text of the Code (October 2026), I do not apply any suspension of the appeal period for the judicial vacation (1 July - 15 September). The period runs through the summer. This is the one point on which I am less than fully certain.

Step 6 - Last day falls on a Saturday and a public holiday.
15 August is the Dormition of the Virgin (a public holiday) and falls on a Saturday in 2026. A period expiring on a Saturday, Sunday or public holiday is extended to the next working day. Rule: Art. 144 para. 3 KPolD (together with Art. 241 of the Civil Code). The next working day is Monday 17 August 2026.

Step 7 - Conclusion.
The last day on which the appeal can validly be filed is Monday 17 August 2026. The appeal is filed by lodging the appeal document with the clerk's office of the court that issued the judgment (Art. 495 para. 3 and Art. 511 KPolD). It must be lodged by the end of that day.

RESULT: deadline = 2026-08-17; rule = Art. 518 para. 1 KPolD (30 days from service), counted from the day after service per Art. 144 para. 1, and extended to the next working day per Art. 144 para. 3 because day 30 (Sat 15 Aug 2026) is a weekend and public holiday
