No. The package is abandoned (last release 2016-09-25, repository archived) with no maintenance path forward. While it has low install friction and a permissive license, its age and lack of updates mean it will not receive bug fixes, security patches, or compatibility updates for modern Python versions.AI-flagged interpretation of the facts on this page — verify before relying

- Requires a timezone object; the fact sheet does not specify which timezone library is expected or whether it is declared as a dependency.
- Low friction installation with no runtime dependencies.

What it is and what it does
tzcron is a library for parsing cron and quartz schedule expressions and iterating over their next occurrence times while respecting timezone information. You define a schedule by passing a cron expression string and a timezone object, then call next() on the resulting Schedule object to get successive datetime instances when that schedule fires.
The package is designed for scenarios where you need to compute future execution times for a cron-like schedule in a timezone-aware context. It wraps the scheduling logic into an iterable interface, making it straightforward to generate a sequence of upcoming times. The library has been abandoned since its initial 1.0.0 release in September 2016, with no subsequent maintenance or updates.
Use it for
- Generate upcoming execution times for a cron job in a specific timezone for logging or UI display.
- Build a timezone-aware task scheduler that needs to compute when a cron expression will next fire.
- Validate or preview cron/quartz expressions by iterating over their next few occurrences.
- Coordinate scheduled tasks across multiple timezones by computing local occurrence times.
