Definitions
In plain terms
A day can be a business day for one market and a holiday for another, so the relevant calendar must always be named.
Technical
Business-day calculations require a calendar identifier, jurisdiction or product scope, holiday version, and roll convention when moving dates.
Scope
It is not universally equivalent to Monday through Friday or to a trading day.
Examples
- A governed dataset records business day explicitly instead of inferring it from an ambiguous field.
Common misconceptions
- Business Day does not have one universal meaning without its stated market, source, and time context.
