## What it is
A Go library that parses date strings in many formats without knowing the format in advance, using a byte-scanning state machine for speed. It also ships a small CLI for testing date formats.

## Use cases
- parse arbitrary date strings in go
- detect date format from a string
- parse dates without knowing the layout
- convert messy datetime strings to time.Time
- get the layout string for a parsed date
- handle ambiguous mm/dd vs dd/mm dates

## When to choose
- you receive date strings from many sources with unknown formats
- you need fast parsing compared to trying many layouts
- you want a strict mode that rejects ambiguous dates

## When to avoid
- you always know the exact date format in advance
- you need dd/mm/yyyy preferred over mm/dd/yyyy for ambiguous dates
- you need active development or new features

## Facets
- artifact type: library
- maturity: maintenance
- function: parser, date-time
- domain: developer-tools, parsers
- platform: go, cli, cross-platform
- tags: date-parsing, go-library, state-machine, format-detection
