Every EU AI Act date, counted from today.
Today is 9 Oct 2026. Three of the five dates have passed. The high-risk rules moved. The other dates kept their day, with the exceptions written on each row.
Which dates are yours?
- Applies now Prohibited practices and AI literacyEvery provider and deployer. Article 4 asks for measures that support AI literacy among the people who run your systems, not a guaranteed level.Points added to Article 5 by 2026/1744: 2 Dec 2026 Articles 4 and 5The ten prohibited practices →
- Applies now General-purpose AI modelsCompanies that provide a general-purpose AI model. Not those that only use one.Models already on the market: 2 Aug 2027, Article 111(3) Chapter VDo the model rules apply to you? →

That is what the check is for. No account needed, and every answer cites its article.
Check your AI systems, free“Postponed” covers two dates, not the Act.
Regulation 2026/1744 moved the start of the high-risk rules. The prohibitions, AI literacy, the rules for general-purpose models and the transparency duties kept their dates, apart from the two later dates in the table. A company that stopped looking in 2026 may already be late on those.
Every date that follows from a classification.
The rows below are the deadline tool this page carried before the redesign: every date with its provision, by classification, including the transitional rules for systems already on the market. Pick a classification to narrow them.
Every operator, whatever the classification
The Regulation as a whole applies from 2 August 2026 under Article 113, second paragraph.
Applies regardless of the classification input.The Article 5 prohibitions have applied since 2 February 2025 under Article 113, third paragraph, point (a) — with the exception written into the same point: Article 5(1), first subparagraph, points (ba) and (bb), and Article 5(1a) and (1b) apply from 2 December 2026.
Applies regardless of the classification input.The Article 4 AI literacy duty has applied since 2 February 2025 — it sits in Chapter I, which Article 113, third paragraph, point (a) put on that date.
Applies regardless of the classification input.The Article 50 transparency duties apply from 2 August 2026: Chapter IV sits in no exception, so it takes the general date in Article 113, second paragraph — save that Article 111(4) gives providers of systems generating synthetic content that were placed on the market before 2 August 2026 until 2 December 2026 to comply with Article 50(2).
Applies regardless of the classification input.Classified as Annex III high-risk
The high-risk regime — Chapter III, Sections 1, 2 and 3, with the exception of Article 6(5) — applies from 2 December 2027 to systems classified as high-risk pursuant to Article 6(2) and Annex III (Article 113, third paragraph, point (c), as amended by Regulation (EU) 2026/1744).
For a system classified as Annex III high-risk — the classification is the input, not the finding.Article 43 (conformity assessment) and Article 49 (registration) sit in Chapter III, Section 5, which point (c) does not defer — so they keep the general date in Article 113, second paragraph: 2 August 2026.
For a system classified as Annex III high-risk — the classification is the input, not the finding.How Section 5 is meant to operate while the Section 1 classification rules are not yet in application is a question the amending regulation does not answer. We state it as open rather than resolve it.
For a system classified as Annex III high-risk — the classification is the input, not the finding.Article 113, third paragraph, point (c), as amended by Regulation (EU) 2026/1744
Classified as Annex I high-risk
The high-risk regime — Chapter III, Sections 1, 2 and 3, with the exception of Article 6(5) — applies from 2 August 2028 to systems classified as high-risk pursuant to Article 6(1) and Annex I (Article 113, third paragraph, point (c), as amended by Regulation (EU) 2026/1744).
For a system classified as Annex I high-risk — the classification is the input, not the finding.The rest of the Annex I map — the sectoral conformity route and the notified-body dates — is in the deadlines table, row by row.
For a system classified as Annex I high-risk — the classification is the input, not the finding.Article 113, third paragraph, point (c), as amended by Regulation (EU) 2026/1744
Classified as not high-risk
No high-risk date attaches. What binds you are the dates every operator carries — the rows above. A classification is a dated answer: if the system changes, the question is asked again.
For a system classified as not high-risk — the classification is the input, not the finding.Provider of a general-purpose AI model
The obligations for providers of general-purpose AI models in Chapter V have applied since 2 August 2025 under Article 113, third paragraph, point (b) — a point whose own text excepts Article 101.
For a system classified as a general-purpose AI model — the classification is the input, not the finding.A general-purpose AI model placed on the market before 2 August 2025 must be brought into compliance by 2 August 2027 under Article 111(3), which Regulation (EU) 2026/1744 did not touch.
For a system classified as a general-purpose AI model — the classification is the input, not the finding.Article 111(3) and Article 113, third paragraph, point (b), Regulation (EU) 2024/1689
If the system was already on the market
An operator of a high-risk AI system placed on the market or put into service before the date of application of Chapter III referred to in Article 113 falls under the Regulation only if, as from that date, the system is subject to significant changes in its design — Article 111(2), as replaced by Regulation (EU) 2026/1744. Whether a change is significant is a judgment, and this page does not make it.
A condition, not a question: whether it holds for your system is not this page's call.The replaced paragraph refers in the singular to the date of application of Chapter III, and Article 113 now carries two such dates — 2 December 2027 and 2 August 2028. Which one governs a given legacy system is not resolved by the text, and we say so rather than pick one.
A condition, not a question: whether it holds for your system is not this page's call.In any case, providers and deployers of high-risk AI systems intended to be used by public authorities must comply with the Regulation's requirements and obligations by 2 August 2030 — the second sentence of Article 111(2), which kept that date through the amendment.
A condition, not a question: whether it holds for your system is not this page's call.A provider of an AI system that generates synthetic audio, image, video or text content and that was placed on the market before 2 August 2026 must comply with Article 50(2) by 2 December 2026 under Article 111(4), added by Regulation (EU) 2026/1744. Whether a system generates such content is a fact about the system — an input this page does not take.
A condition, not a question: whether it holds for your system is not this page's call.The Annex X large-scale IT systems carry their own transitional rule in Article 111(1); it is in the deadlines table.

No dates render here, because every date on this page attaches to a classification, and a guessed classification produces confident, wrong deadlines. The classifier decides it in your browser, and each answer cites the article it rests on.
This tool keeps no record of what you pick: its script stores nothing and sends nothing, and the build reads the delivered page on every run and stops if that changes. The full table, including the rows this page does not render: every EU AI Act date, with the article behind it.
