The short answer
A founding story often compresses several acts into one date. The more useful question is what each date dates: assent, commencement, a public opening, legal authorisation, the first issue of money or the withdrawal of an older currency. These can be connected without being interchangeable.

Keep the object beside its date
Ask what the record establishes and which further claim needs different evidence.
| Record | Supported reading | Boundary |
|---|---|---|
| Versioned Act header | Assent and split commencement. | Not every revised clause as originally enacted. |
| Currency history | Legal authorisation of notes. | Not proof of first circulation. |
| Statistical definitions | Issue and separate withdrawal dates. | Not a single switch for all money. |

Assent
Not a blanket commencement date.
Notes authorised
Legalisation and first issue are different events.
Final listed withdrawal
The selected record concerns the older coins.
Read the revision label before the historical header
The consulted Central Bank of Kenya Act is the revised 2018 [2014] text. Its header gives assent as 24 March 1966, commencement of Parts I–IV as 23 May 1966 and Parts V–IX as 14 September 1966. The contents place establishment and management in the earlier group and currency in the later group.
This is evidence from a later consolidation’s historical header. It is not an acquired as-enacted original. The split dates prevent the assumption that every provision operated at assent, while the revision label prevents a second error: treating all wording in a later consolidated statute as necessarily identical to its first version.

Opening a bank and issuing money are separate records
The bank’s history dates the public opening to 14 September 1966. A photograph caption describes Governor Leon Baranski presenting notes to Kenyatta the following day.
The currency history says the notes were legalised under L.N. 252 on 1 July 1966.
The contemporary Statistical Abstract dates their first issue to 14 September 1966 and coins to 10 April 1967.
A presentation photograph records an event involving people and objects. It should not displace the documented first-issue date. Likewise a legal authorisation and a physical issue can have different dates without contradiction. The appropriate verb does more work than a vague label such as “currency began”.
Replacement was a transition, not a single switch
The abstract records that East African Currency Board notes ceased to be legal tender on 14 September 1967 and its coins on 10 April 1969.
The institutional history situates the national bank after the regional currency-board arrangements.
The contemporary appointment notice identifies Gichuru as Finance minister and Mboya as Economic Planning minister.
The overlapping sequence matters. National notes could be issued before older notes were withdrawn; notes and coins also followed different schedules. The ministerial record supplies political responsibility without making the governor, the cabinet or the legislature interchangeable. Institution building was a coordinated change in authority, administration and circulating instruments.
Worksheet: repair the event ledger
Invented researcher’s ledger uses four headings: “law approved”, “all provisions operating”, “first issue”, “old money withdrawn”. It assigns the same founding date to all four and uses a ceremonial photograph as proof. Rewrite the headings where necessary, identify which records answer each question, and explain whether one replacement currency requires one withdrawal date.
Reference answer: retain assent as its own event, then split commencement by the stated groups of Parts. Use the statistical issue entry rather than the presentation caption for circulation. Separate old notes from old coins when recording withdrawal. The two withdrawal entries show why a single undifferentiated “old money” date loses information.
No arithmetic is needed to repair a category error. A good ledger keeps event, object, date, source version and limits together. Where a record is retrospective, state that fact instead of silently upgrading it to an original enactment or a contemporary observation.

Common questions
- Can a ceremony establish the first circulation date?
- It establishes the event it records. A claim about circulation needs the issue record, not an assumed equivalence between ceremony and use.
