⚠️ Work in Progress ⚠️

Chrono is a date and time package for Dart supporting all platforms. It offers strongly-typed data classes for timezone-independent (plain/local) date, time, and different durations based on the proleptic Gregorian calendar, including:

• arithmetic operations and conversions
• parsing and formatting for a subset of [ISO 8601], [RFC 3339], and [CC 18011:2018]
  • this is implemented for Instant and the date/time classes, but still missing for durations

The following features are not implemented, but could be added in the future:

• timezone support (work in progress)
• customizable parsing and formatting
• internationalization

Chrono is split into multiple packages:

• chrono: The core package, providing date, time, and duration classes.
• chrono_timezone_compiler (WIP): A Dart program reading the [IANA Time Zone Database] and generating timezone data for Chrono.
