pyobjc-framework-CalendarStore
Wrappers for the framework CalendarStore on macOS
Decision gist · record as of 2026-08-14
Yes, if you are building on macOS and need direct access to the system CalendarStore. The package is actively maintained, has no known vulnerabilities, and carries a permissive license. Install friction is low. However, it is macOS-only and requires familiarity with Objective-C API translation; it is not a high-level calendar library.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- macOS 10.5 or later required; Python 3.10+ required; only runs on macOS systems with CalendarStore framework available.
- Low install friction with pure-Python wheel distribution.
- Actively maintained with a release 3 days old and recent repository activity.

What it is and what it does
This package wraps Apple's CalendarStore framework for use in Python on macOS, giving developers direct access to the system's iCal data store. It sits on top of pyobjc-core and pyobjc-framework-Cocoa, translating Objective-C calls into Python. You can fetch calendar records and tasks, modify them, and subscribe to change notifications when iCal data updates.
It is a thin binding layer rather than a high-level abstraction—the package explicitly directs users to Apple's framework documentation and PyObjC's general translation guides. This makes it suitable for developers who need deep integration with macOS calendar systems and are comfortable reading Objective-C API docs and adapting them to Python.
Use it for
- Build macOS desktop applications that read or modify user calendars and tasks stored in iCal.
- Create automation scripts that monitor calendar changes and trigger actions when events are added or modified.
- Integrate Python tools with the native macOS calendar system for scheduling or calendar-aware workflows.
- Develop system utilities that need programmatic access to iCal records without going through third-party calendar APIs.
