The Public Holidays (Ascension) Ordinance, 1945 has been in force since 24 November of that year. Its First Schedule appoints six days and no others:
Good Friday · Easter Monday · The official birthday of Her Majesty the Queen · Ascension Day · Christmas Day · Boxing Day, the 26th day of December
We were showing Ascension keeping New Year’s Day, the Early May Bank Holiday and the Spring Bank Holiday — three days its law does not appoint — and not keeping Ascension Day, which is the feast the island is named for.
How a calendar gets borrowed
The reason was written down in our own collection notes, in plain sight, months before anybody noticed it mattered. Ascension and Tristan da Cunha, the note said, “reference the UK bank holiday list as the sovereign framework”. It even predicted the consequence in the same breath: the territories may add local days, e.g. Ascension Day, not listed here.
The reasoning is easy to follow and entirely wrong. Ascension is a British Overseas Territory, so in the absence of anything better the British list looks like a reasonable default. But sovereignty is not a calendar. Ascension has legislated its own public holidays since 1945, and the list it legislated is not the one Westminster keeps.
Read across the three territories that share the government of St Helena, Ascension and Tristan da Cunha, and the point makes itself. They agree on almost nothing:
- Ascension — six days, including Ascension Day.
- Tristan da Cunha — eight, including Epiphany and Whit Monday, plus a ninth appointed by By-Law 2 and dated by nobody in advance.
- Saint Helena — its own notice each year, with St Helena’s Day on 21 May, the date the island was sighted in 1502, and an August bank holiday where Britain’s summer one falls.
One government, three legislatures, three calendars, no overlap you could safely assume.
The clause worth reading twice
Section 5(1) of the Ascension Ordinance lets the Island Council move a public holiday “on account of the arrival of any ship.”
There is a whole geography in that sentence. On an island where the supply vessel is the event that structures the year, the calendar yields to the shipping. Section 5(2) adds that the Governor may proclaim a day of national importance; section 2(3) says that when a holiday other than Christmas falls at a weekend, the Governor proclaims either the preceding Friday or the following Monday — the law declining to fix which, seventy years before anyone tried to compute it.
Tristan’s equivalent is By-Law 2: a public holiday called Queen’s Day, kept annually “on a date in October, not being a Sunday, to be fixed and announced by the Administrator as may be most convenient.” A day that certainly exists every year, on a date that cannot be calculated from anything.
What changed
Ascension now carries its six appointed days, with Ascension Day at Easter plus thirty-nine — a Thursday, every year. Tristan carries its nine. Saint Helena carries the nine in the Chief Secretary’s notice, including the King’s Birthday, which that notice appoints and dates separately.
Across the three, the borrowed calendar had produced eleven days that no local instrument appoints and left out fifteen that it does.
One footnote on the Saint Helena source, since it bears on how fresh any of this can be: the government’s public-holidays page still serves the 2024 notice. We re-fetched it this month and it was byte-for-byte the file we captured earlier. There is no newer one to find. A record can be as current as the authority allows and still be two years old.
