# Description
<!--
Thank you for improving Nushell. Please, check our [contributing
guide](../CONTRIBUTING.md) and talk to the core team before making major

This PR updates the following functions so they may also be used in a
polars expression:

- `polars get-day`
- `polars get-hour`
- `polars get-minute`
- `polars get-month`
- `polars get-nanosecond`
- `polars get-ordinal`
- `polars get-second`
- `polars get-week`
- `polars get-weekday`
- `polars get-year`

Below examples provide a comparison of the two contexts in which each of
these commands may be used:

```nushell
# Returns day from a date (current use case)
  > let dt = ('2020-08-04T16:39:18+00:00' | into datetime --timezone 'UTC');
    let df = ([$dt $dt] | polars into-df);
    $df | polars get-day

# Returns day from a date in an expression (additional use case provided by this PR)
  > let dt = ('2020-08-04T16:39:18+00:00' | into datetime --timezone 'UTC');
    let df = ([$dt $dt] | polars into-df);
    $df | polars select (polars col 0 | polars get-day)
  ╭───┬───╮

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
No breaking changes. Each of these functions retains its current
behavior and gains the benefit that they can now be used in an
expression as well.

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```
-->
Tests have been added to each of the examples.

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
