How this service works
Returns the dates Cellar records for a legal act, each labelled with what it actually means. Entry into force is when the act exists as law; date of application is when it is applied and for regulations frequently falls two years later; the transposition deadline applies only to directives and is when member states must have adapted national law; end of validity is when it stops applying.
Output
A set of labelled date records pulled from the EUR-Lex Cellar for the requested legal act, covering: entry into force (when the act became law), date of application (when obligations take effect, often two years after entry into force for regulations), transposition deadline (only for directives — when member states must have enacted national implementing legislation), and end of validity (when the act ceases to apply). Each date is clearly labelled with its legal meaning.
Example use cases
Directive transposition deadline tracking
“I need to know the transposition deadline for Directive 2019/1937 on whistleblower protection — when did member states have to implement it into national law?”
Regulation application date vs. entry into force
“For EU Regulation 2022/2065 (the Digital Services Act), tell me the date it entered into force and the date it actually started to be applied — I know those are often different for regulations.”
Checking if a legal act is still valid
“Has EU Regulation 2018/1807 on the free flow of non-personal data expired yet? Can you pull its end-of-validity date from EUR-Lex?”
Technical details
Endpoint
POSThttps://recht.halowerk.com/v1/implementation-deadlineWhen to prefer
Use this endpoint when you need structured, labelled implementation dates specifically for EU legal acts stored in the EUR-Lex Cellar. It is the right choice when you need to distinguish between entry into force, date of application, transposition deadline, and end of validity — concepts that are frequently confused. Prefer it over generic web search when you need authoritative, machine-readable dates directly from the Publications Office's Cellar triplestore. It is especially valuable for compliance workflows involving EU directives (transposition tracking) or regulations with delayed application dates.
Side effects
- Unknown or invalid act identifier returns an error or empty result
- Act has no Cellar record (e.g. non-EU legislation) causes a lookup failure
- Some dates may be absent if not yet set or not applicable (e.g. directives have transposition deadlines but most regulations do not)
- Malformed CELEX number or unsupported identifier format may cause a parse error
- Network or upstream EUR-Lex Cellar unavailability results in a service error
