# types-croniter — Typing stubs for croniter

License: permissive · Maintenance: active · Downloads: 15.6M/mo

## What it is and what it does

types-croniter is a type stub package that bridges the gap between the croniter scheduling library and Python's static type checkers. It provides type annotations for croniter's public API, allowing mypy, pyright, and other type checkers to understand and validate code that uses croniter for cron expression parsing and job scheduling.

This stub package is maintained as part of the typeshed project and is kept in sync with croniter 6.2.4. It has no runtime dependencies and installs as a pure metadata package. Type checkers automatically discover and use these stubs when analyzing code, making it possible to catch type errors in croniter usage before runtime.

Use it for:

- Add type safety to projects using croniter for cron expression parsing and validation in scheduled task systems.
- Enable IDE autocompletion and type hints for croniter objects in development environments.
- Enforce type correctness in CI/CD pipelines using mypy or pyright to catch scheduling logic errors early.
- Support gradual typing adoption in legacy codebases that use croniter by providing accurate type information.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides type stubs for the croniter package, enabling type checkers like mypy and pyright to validate code that uses croniter for cron expression parsing and scheduling.

Yes, if you use croniter and want type checking support. Install it alongside croniter to enable static type validation with mypy or pyright. No runtime cost, actively maintained, and permissively licensed. Essential for type-safe scheduling code.

## Install

pip install types-croniter
uv add types-croniter
poetry add types-croniter

## Installing types-croniter

Before you install: Low friction install with no runtime dependencies. Actively maintained as part of typeshed, tested with mypy 2.2.0 and pyright 1.1.411, and released 34 days ago.

License in practice: Licensed under Apache-2.0 (permissive), allowing use in most projects without significant legal constraints.

Quickstart:

pip install types-croniter

# Then use croniter in your code; type checkers will now understand its types
from croniter import croniter
from datetime import datetime

cron = croniter('0 0 * * *', datetime.now())

Requires Python 3.10 or later. The underlying croniter package must also be installed for runtime use.

Verify before relying:

- Whether installing types-croniter alone (without croniter) is sufficient for type checking, or if croniter must be installed separately
- Coverage completeness: whether all public croniter APIs are fully annotated in this stub version
