An Extended Date Time Format (EDTF) / ISO 8601-2 parser and English language rendering
toolkit for Elixir.

## Compatibility

### EDTF / ISO 8601-2
EDTF fully implements [EDTF](http://www.loc.gov/standards/datetime)
levels 0, 1, and 2 as specified by ISO 8601-2

## Installation

Add `edtf` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:edtf, "~> 1.0.0"}
  ]
end
```

## Usage

See `EDTF.parse/1`, `EDTF.validate/1`, and `EDTF.humanize/1`.

## Notes

- Some human-readable dates containing Level 2 qualifications and years with significant digits, 
  may produce less specific results than desired.
