A holiday in part of a country and not the rest — and the commonest source of a wrong date.
A regional holiday is declared by a subdivision rather than a national government: a German Land, a Spanish comunidad, a Swiss canton, a UK nation. Where the subdivision holds the competence, the national list is genuinely incomplete rather than merely summarised.
This is the single commonest way a date goes wrong in practice. Asking a holiday library for a country returns the national list, the answer looks complete, and it silently omits every regional day — which is why a payroll run for Bavaria or Scotland off a national calendar misses days every year.
The corpus holds 653 subdivisions for this reason, and asking for a country returns national rows only, deliberately. It refuses to guess which region you meant.
Each of these is a public holiday in part of a country and an ordinary working day in the rest of it. None appears on the national list.

Regional means a subdivision with legislative competence. Local means a city or district, usually under a delegated power.
Regional holidays are public holidays. The word records that the authority declaring them is not the national one.
