Calcori
Calcori is a calculator-first utility site for work time, dates and business days. The goal is simple: give a useful answer immediately, then explain the method clearly.
Localized, not duplicated
Country versions use the same calculation engine where appropriate, while terminology, holidays and local assumptions remain specific to each market.
Built for clarity
No account is required for the core calculators. Pages are designed around one clear task, fast interaction and transparent arithmetic.
