Question: last day to file an appeal against the final judgment of the Multi-Member Court of First Instance of Heraklion, published 2 July 2026 and served on the appellant company (seated in Heraklion) at the plaintiff's initiative on Thursday 16 July 2026.

Step 1 - Which deadline applies and what starts it (Art. 518 para 1 CCP).
The appeal must be filed within 30 days of service of the final judgment when the appellant resides (has its seat) in Greece; the deadline is 60 days only if the appellant lives abroad or its residence is unknown. The company is seated in Heraklion, so the deadline is 30 days. Service by the opposing party (the plaintiff) to the company starts the deadline for the company. Because the judgment was served, the long 2-year deadline from publication (Art. 518 para 2) does not apply, and the publication date (2 July 2026) is irrelevant.

Step 2 - Starting point (Art. 144 para 1 CCP).
A deadline set in days begins on the day after the event that starts it. The day of service (Thursday 16 July 2026) does not count. Day 1 = Friday 17 July 2026.

Step 3 - Days counted before August.
17 July to 31 July 2026 inclusive = 15 days (days 1-15). 15 days remain.

Step 4 - August suspension (Art. 147 para 2 CCP).
During August, deadlines for filing appeals and other legal remedies (and for filing cassation) are suspended. 1-31 August 2026 is not counted, and the count resumes on 1 September 2026.

Step 5 - Days counted after August.
The remaining 15 days run from 1 September to 15 September 2026 inclusive (days 16-30). Day 30 = Tuesday 15 September 2026.

Step 6 - End of the deadline and check for holidays (Art. 144 para 1 and para 3 CCP).
The deadline ends when the whole of its last day has passed (Art. 144 para 1). If the last day were a Saturday, Sunday or public holiday, the deadline would roll over to the next working day (Art. 144 para 3). Tuesday 15 September 2026 is an ordinary working day and not a public holiday, so no extension applies.

Conclusion: the company can file the appeal (by lodging it with the registry of the court that issued the judgment, Art. 495 para 1 CCP) up to and including Tuesday 15 September 2026.

RESULT: deadline = 2026-09-15; rule = Art. 518 para 1 CCP (30 days from service), with Art. 144 para 1 and Art. 147 para 2 CCP (August suspension)
