A day banks are closed by law — which is not the same as a public holiday.
A bank holiday is a day on which banks are closed and on which, in some jurisdictions, financial instruments cannot be presented or fall due. The term is often used loosely to mean any day off work, but in the countries that define it in statute it is narrower and more consequential than that: it governs when payments clear, when a cheque may be presented, and when a contractual deadline falling on that day moves.
The United Kingdom is the case that gives the term its name. The Banking and Financial Dealings Act 1971 lists bank holidays in a schedule, differently for England and Wales, Scotland, and Northern Ireland, and permits further days to be appointed by royal proclamation. Scotland's list differs from England's in both January and August, which is why a payment instruction that assumes one calendar for 'the UK' will occasionally be wrong.
Elsewhere the word carries no legal weight at all. In the United States there is no federal definition; the Federal Reserve publishes the days its own services are closed, and commercial banks follow. The effect is similar and the mechanism is not, and a contract drafted around 'bank holidays' in a jurisdiction that does not define them is drafted around a convention.
| Jurisdiction | Instrument |
|---|---|
| GB | Banking and Financial Dealings Act 1971, s.1 and Sch.1 Separate schedules for England and Wales, Scotland, and Northern Ireland. s.1(3) allows further days by proclamation. |
| Jurisdiction | Meaning |
|---|---|
| GB | Statutory, and listed separately for the three legal jurisdictions. Additional days may be proclaimed. |
| US | Conventional. No federal definition; the Federal Reserve publishes its own closures and commercial practice follows. |
| IE | Statutory, but the governing term is 'public holiday' under the Organisation of Working Time Act 1997. |
Bank holiday is a term of United Kingdom statute, so these examples do not travel — all three are UK dates. What they show is that the schedules differ: the 1971 Act lists bank holidays separately for each legal jurisdiction, and none of these three days is a bank holiday in all of them.

A bank holiday closes banks. A public holiday need not, and frequently does not — nor does a bank holiday oblige any other employer to close.
A bank holiday says the bank is shut. A value date says when money is actually available, which the closure affects but does not define.
A bank holiday is the occasion. Substitution is the rule that moves it when it lands on a rest day — which is why Scotland's 2 January holiday is sometimes taken on the 4th.
