About Working Days Calculator
What We Do
Working Days Calculator is a free, precision-engineered web application designed to help HR teams, project managers, financial planners, and individuals count exact business days between two dates. We eliminate the manual chore of cross-checking weekend schedules and national statutory public holidays.
Our Methodology
Our calculation engine evaluates calendar dates sequentially in UTC, preventing daylight saving time shifts and timezone drift. It supports customized weekend models (Sat-Sun, Fri-Sat, or 4-day schedules) and handles statutory in-lieu observed holidays accurately.
Accuracy Standards
We continuously maintain and verify statutory holiday calendars across 11+ major jurisdictions and all 50 US states. Every calendar is referenced directly from official government gazettes, labour departments, and central banking schedules.
How Public Holidays Are Handled
When a jurisdiction is selected, our system automatically factors in official public holidays. If a public holiday falls on a weekend, standard statutory substitution rules (such as observing on the subsequent Monday) are strictly evaluated according to local labour laws.
