Yes, if you need working-day calculations for Brazil or the other supported countries and can accept a dormant package. The low install friction and permissive license make it a practical choice for financial calculations or business logic. However, verify that holiday calendars remain accurate for your use year, and monitor whether the package receives updates for future Python versions—no maintenance activity has been recorded since release.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with only two runtime dependencies (python-dateutil and six).
- Package is dormant since its 2023-12-30 release—no commits or updates tracked since then, which may affect reliability for future Python versions or holiday calendar changes.

What it is and what it does
Workadays is a date-calculation library that computes working days, calendar days, and financial 360-day intervals between two dates. It includes built-in holiday calendars for Brazil (including state-level holidays), United States, Luxembourg, United Kingdom, and Argentina, accounting for weekends and holidays in its calculations.
The package provides functions to count working days between dates (networkdays), add a number of working days to a start date (workdays), calculate calendar days or 360-day basis intervals (days and days360 with American or European methods), and check whether a specific date is a holiday, weekend, or working day. It depends on python-dateutil and six for date handling and Python 2/3 compatibility.
Use it for
- Calculate business day deadlines in financial contracts or loan agreements using 30/360 day-count conventions
- Determine working-day delivery dates in e-commerce or logistics systems accounting for regional holidays
- Compute accrued interest or bond pricing using American or European 360-day basis methods
- Validate whether a date is a working day in payroll or HR systems for Brazil or other supported countries
- Generate holiday calendars for specific countries and years for scheduling or calendar applications
