Chrono
Chrono is a JavaScript natural language date parser that converts unstructured text and relative date expressions into structured date objects. It functions as a multi-locale date parser and expression engine designed to resolve time expressions globally.
The library is customizable, allowing for the definition of custom regular expression patterns and refinement rules to extract business-specific date formats. It provides mechanisms to resolve relative terms like tomorrow or next Friday based on a specific reference date.
The system covers international date formatting across various regional locales and provides timezone offset mapping to associate abbreviations with specific offsets. It includes capabilities for natural language extraction and relative date resolution.
Features
- Date String Parsers - Converts unstructured text and relative date expressions into structured JavaScript date objects.
