How soon must a personal data breach be notified?

Without undue delay and, where feasible, within 72 hours of the controller becoming aware of it, to the supervisory authority, which in Greece is the Hellenic Data Protection Authority (GDPR Article 33 §1). A later notification must give reasons for the delay.

What are the NIS2 and DORA incident reporting deadlines?

NIS2 (Greek Law 5160/2024, Article 16 §4): an early warning within 24 hours of becoming aware of a significant incident, an incident notification within 72 hours, and a final report no later than one month after the notification. DORA (Delegated Regulation (EU) 2025/301, Article 5): an initial notification within 4 hours of classifying the incident as major and no later than 24 hours from becoming aware, an intermediate report within 72 hours, and a final report within one month.

How is the August suspension applied?

Under ΚΠολΔ Article 147 §2, 1–31 August is not counted for the periods the article lists, such as appeal, cassation and objection to default. It does not apply to every procedural period. In tax and administrative disputes, August is left out under their own provisions (ΚΦΔ 72 §1, ΚΔΔ 61 §4).

What happens if a deadline falls on a weekend or public holiday?

If the last day is a Saturday, Sunday or public holiday, the period ends on the next working day (ΚΠολΔ 144 §§1, 3 · ΑΚ 242), at 19:00. The calculation covers national holidays, including Clean Monday, Good Friday, Easter Monday and Whit Monday, but not local ones.

Which deadlines can it calculate?

Appeal, cassation and objection to default under the ΚΠολΔ; GDPR, NIS2 and DORA notification deadlines; administrative objections under the ΚΦΔ (ν. 5104/2024); court challenges to ΔΕΔ decisions; and court challenges on the merits under the ΚΔΔ. The «deadlines at a glance» table lists other common periods too.

Can I add the deadlines to my calendar?

Yes. Each result downloads as a calendar event (.ics) with a reminder three days before, and works with Outlook, Google Calendar and Apple Calendar.

Where are my details processed?

In data centres in the European Union. Your description is used only to find the elements of the deadline, such as the date of service and where the parties live, and to ask for any that are missing. The date itself is always computed from the text of the provision.

Does it replace legal advice?

No. Calculations are indicative. Always verify against the primary source and check for any special provisions that apply.
