We were publishing fourteen Indian holidays, every one of them scoped to the whole country and marked as a general closure — the entire country shut, fourteen times a year. India does not work that way, and the mistake is not a matter of degree. It is a category error about who is entitled to close what.
In India, at least four different bodies can shut something, and they are not ranked versions of each other:
| what closes | who says so | how long it holds |
|---|---|---|
| the three national holidays | Government of India | permanently |
| central government offices | an annual Office Memorandum | one year |
| banks, state by state | the Reserve Bank of India, under the Negotiable Instruments Act 1881 | one year |
| state offices | each state government | varies |
A holiday can appear on one of those lists and none of the others. Ask “is the 15th a holiday in India” and there are four correct answers depending on whether you are a bank, a central government office, a state office, or everybody.
What the bank matrix shows
The RBI publishes a matrix across its regional offices, roughly one per state and union territory. Read down a column and the fourteen sort themselves out immediately.
Republic Day, 26 January 2026 — marked at all thirty-four. Genuinely national.
Good Friday, 3 April 2026 — marked at twenty-eight of thirty-four. Not marked at Agartala, Chandigarh, Guwahati, Jaipur, Jammu or Srinagar. Whatever else it is, it is not a nationwide closure, and we were selling it as one.
Two other things fall out of the same document. Election days are one-off state bank holidays — Kerala on 9 April, Tamil Nadu on the 23rd, West Bengal on the 29th, in 2026 — a category of closure that is real, scheduled, and absent from our records entirely. And 1 April is “Banks’ Closing of Accounts”, which is a bank being shut for a reason that is not a holiday at all, and for which our vocabulary has no word.
The part that does not stay fixed
The three national days now carry the RBI matrix as provenance, marked as good until the end of 2026 and no further.
That is not caution, it is arithmetic. The matrix is reissued annually. Reading this year’s document tells you about this year. A calendar that quoted it once and left the citation in place would be making a claim about 2027 on the strength of a document that does not mention 2027.
Why this is the same error twice
We had already found this shape at a smaller scale: Greek local holidays recorded as closing everything, when a local holiday closes a locality. India is the same defect at national scale, and the reason it is worth naming as a class is that it is invisible from inside a well-formed record. Nothing about “Good Friday, India, closed” is malformed. Every field is populated, the date computes, the source resolves.
It is simply answering a question nobody asked — is this day observed somewhere in India — and presenting the answer to a different one, which is whether your counterparty will be at their desk.
