## What it is
Chrono is a natural language date parser library for JavaScript/TypeScript that extracts dates and times from arbitrary text. It handles relative expressions like 'tomorrow' or '5 days ago' as well as absolute formats, with multilingual support.

## Use cases
- parse dates from natural language text
- extract appointment dates from user input
- convert phrases like 'next Friday' into date objects
- parse dates in multiple languages
- extract date ranges from text

## When to choose
- you need to interpret human-written dates in chat or form input
- you want a lightweight, dependency-free date extraction library
- you need multilingual date parsing

## When to avoid
- you only need to parse strict ISO 8601 or fixed-format dates
- you need a full NLP pipeline beyond date extraction
