When each AI-specific law, regulation and milestone actually takes effect — the instrument, the provision that states the date, the date itself, what it applies to, and the statutory text quoted verbatim from the enacted bill or the official journal. Answers 'when does the Colorado AI Act take effect', 'when does Colorado SB 24-205 take effect', 'when do the EU AI Act high-risk obligations apply', 'when does Texas HB 149 start', 'what date does the Illinois AI hiring law kick in'. Covers US states, the EU, and the UK. Every date is quoted from the instrument itself — a signed bill, a session law, or the Official Journal — because these dates move, often more than once, and a date with no instrument behind it cannot be told apart from a superseded one. Colorado's SB 24-205 was enacted with duties from 2026-02-01, moved to 2026-06-30 by SB 25B-004, and its part 17 is repealed and reenacted with amendments from 2027-01-01 by SB 26-189; the EU AI Act's Annex III high-risk date was moved from 2026-08-02 to 2027-12-02 by Regulation (EU) 2026/1744. Each record names the instrument whose own words state its date, and says which later instrument replaced it.

Provenance — what every record carries

Every record carries source (the URL the value was read from) and source_quote (a verbatim quote from that page stating it). A value you cannot check against its page is indistinguishable from an invented one; these can all be checked. Each record is also individually addressable on the canonical site at its url.

Licence position

Each record quotes one dating clause from an enacted bill, session law, or official journal and links to it. US federal and state statutes and the enrolled bills that make them are government edicts and are not subject to copyright (Banks v. Manchester; Georgia v. Public.Resource.Org, 2020). EU legislation published in the Official Journal is reusable under Commission Decision 2011/833/EU with source acknowledged. UK legislation on legislation.gov.uk is Crown copyright under the Open Government Licence v3.0. No instrument is reproduced in whole; what is taken is a fact plus a short attributed quote linking back.

Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
