# `Spectral.Codec.Date`
[🔗](https://github.com/andreashasse/spectral/blob/main/lib/spectral/codec/date.ex#L1)

Built-in codec for `Date.t()`.

Encodes `Date` structs to ISO 8601 strings (e.g. `"2023-04-01"`) and decodes
them back. Handles `:json` and `:binary_string` formats (returning a binary string)
and `:string` format (returning a charlist).

## Registration

Registered automatically when the `:spectral` application starts. To use a
different codec for `Date.t()`, set it in `config :spectra, :codecs`;
user-configured codecs take precedence over the built-ins.
