It parses standard 5-field cron expressions (minute, hour, day, month, weekday) into lists of valid values or back to string form, and provides an iterator to find the next or previous execution time relative to any datetime. The package supports timezone-aware scheduling via python-dateutil, optional output formatting with month and weekday names, and can validate whether a given datetime matches a cron schedule.\n\nThe package implements Python's iterator protocol, so you can use standard iteration patterns like islice() or for-loops to walk through scheduled execution times. It also supports comparing cron schedules by frequency and can work with both naive and timezone-aware datetime objects. The main constraint is that the schedule iterator is infinite by design, so you must always apply a limit (islice, break condition, or date check) to avoid infinite loops.","worth_installing":"Yes. Low install friction, active maintenance, no known vulnerabilities, and a permissive MIT license make this a safe choice. Install it if you need to parse cron expressions, iterate over scheduled times, or validate datetimes against cron rules. The single dependency on python-dateutil is stable and widely used. Avoid it only if you need sub-minute scheduling (cron-converter does not support seconds)."},"id":"cron-converter","links":{"html":"https://skillfed.io/packages/cron-converter","md":"https://skillfed.io/packages/cron-converter.md","pypi":"https://pypi.org/project/cron-converter/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-12-02","license_spdx":null,"license_treatment":"permissive","name":"cron-converter","python_support":"supports_current","summary":"Cron string parser and scheduler for Python"},"popularity":{"monthly_downloads":2390119,"position":3089,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.3.1"}
