The core classes\u2014IsoWeek and IsoWeekDate\u2014handle parsing from multiple input types, support arithmetic operations (addition/subtraction with integers), comparison, and range generation. IsoWeek lets you list all dates in a week or fetch the nth day; IsoWeekDate gives you the weekday as an integer and the containing ISO week as a string.\n\nThe package also includes optional modules for pandas and polars that convert between datetime series and ISO week strings, plus pydantic integration for validation. A distinctive feature is support for custom offsets\u2014you can shift the week boundary by a timedelta to work with non-standard week definitions. It requires Python 3.10+ and has no mandatory runtime dependencies; pandas, polars, and pydantic are optional.","worth_installing":"Yes. Low install friction, no mandatory dependencies, active maintenance, MIT license, and zero known vulnerabilities make this a safe choice. Install it if you regularly work with ISO week formats or need to integrate week-based logic into pandas, polars pipelines, or pydantic validation."},"id":"iso-week-date","links":{"html":"https://skillfed.io/packages/iso-week-date","md":"https://skillfed.io/packages/iso-week-date.md","pypi":"https://pypi.org/project/iso-week-date/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-04-01","license_spdx":"MIT","license_treatment":"permissive","name":"iso-week-date","python_support":"supports_current","summary":"Toolkit to work with str representing ISO Week date format"},"popularity":{"monthly_downloads":291022,"position":7978,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.3.0"}
