When calendar days are enough
Calendar days are useful when you only need the raw duration between two dates, for example to describe a contract period or compare the length of two project phases.
They are less useful for operational deadlines because they do not account for weekends, public holidays or local working patterns.
When business-day logic matters
Business-day calculations matter when the promise depends on actual working capacity. Payroll cut-offs, invoice due dates, approval windows and service-level targets are all common examples.
As soon as a deadline depends on a specific country, the holiday calendar becomes part of the calculation rather than an afterthought.
