## What it is
Carbon is a lightweight, semantic, and developer-friendly time and date library for Go with zero third-party dependencies and 100% unit test coverage. It supports timezone handling, multiple calendar systems (lunar, Persian/Jalaali, Julian, Hebrew), and i18n, with integrations for GORM and XORM.

## Use cases
- parse and format dates in go
- convert between timezones in golang
- work with lunar or persian calendar dates
- humanize relative times like '3 minutes ago'
- compare and diff dates in go
- integrate datetime handling with gorm models

## When to choose
- you need a rich, chainable datetime API beyond Go's standard time package
- you need multi-calendar or multilingual date support
- you want a dependency-free, well-tested time library

## When to avoid
- you only need basic time operations already covered by the standard library
- your project is not written in Go

## Facets
- artifact type: library
- maturity: active
- function: date-time, internationalization
- domain: developer-tools, backend
- platform: go, cross-platform
- tags: datetime, timezone, lunar-calendar, persian-calendar, hebrew-calendar, jalaali, julian-calendar, gorm-integration, xorm-integration, i18n, semantic-api
