It also includes a holidays module for calculating dates of North American, Mexican, and Jewish holidays, plus Easter across Western, Orthodox, and Eastern Christian traditions.\n\nThe package handles edge cases like dates before the Common Era (using astronomical year notation where 1 BC = year 0), proleptic calendars for dates before their historical adoption, and calendar-specific leap-year rules. Each calendar module provides conversion functions and a monthcalendar() method to generate calendar grids. It is a pure-Python library with low install friction and no system dependencies.","worth_installing":"Yes, if you need reliable calendar conversion or holiday calculation. The library is mature, permissively licensed, has no security vulnerabilities, and supports modern Python versions. The 'aging' maintenance status and 187 days since last release indicate stability rather than abandonment\u2014suitable for stable calendar logic. Install only if you actually need multi-calendar support; the single pymeeus dependency is manageable."},"id":"convertdate","links":{"html":"https://skillfed.io/packages/convertdate","md":"https://skillfed.io/packages/convertdate.md","pypi":"https://pypi.org/project/convertdate/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2026-02-08","license_spdx":null,"license_treatment":"permissive","name":"convertdate","python_support":"supports_current","summary":"Converts between Gregorian dates and other calendar systems"},"popularity":{"monthly_downloads":4360640,"position":2322,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"2.4.1"}
