## Description

## Typing stubs for python-dateutil

This is a [type stub package](https://typing.python.org/en/latest/tutorials/external_libraries.html)
for the [`python-dateutil`](https://github.com/dateutil/dateutil) package. It can be used by type checkers
to check code that uses `python-dateutil`. This version of
`types-python-dateutil` aims to provide accurate annotations for
`python-dateutil==2.9.*`.

This package is part of the [typeshed project](https://github.com/python/typeshed).
All fixes for types and metadata should be contributed there.
See [the README](https://github.com/python/typeshed/blob/main/README.md)
for more details. The source for this package can be found in the
[`stubs/python-dateutil`](https://github.com/python/typeshed/tree/main/stubs/python-dateutil)
directory.

This package was tested with the following type checkers:
* [mypy](https://github.com/python/mypy/) 2.3.0
* [pyright](https://github.com/microsoft/pyright) 1.1.411
* [ty](https://docs.astral.sh/ty/) 0.0.59

It was generated from typeshed commit
[`e0efbeef901e9b6998d016e1ab9352678f09ae77`](https://github.com/python/typeshed/commit/e0efbeef901e9b6998d016e1ab9352678f09ae77).

## AI interpretation — verify before relying

Provides type hints for python-dateutil, enabling static type checkers like mypy and pyright to validate code using dateutil's date and time functionality.

Verdict: A lightweight, actively maintained type stub package with no dependencies and permissive licensing. Tested with mypy 2.3.0, pyright 1.1.411, and ty 0.0.59. No known vulnerabilities.
