Carbon is a PHP library extending the native DateTime class with a fluent, immutable-friendly API for date and time manipulation. It supports date arithmetic, timezone conversion, comparisons, and human-readable localized formatting in hundreds of languages.

Use cases

• format dates as '2 minutes ago' in PHP
• add or subtract days and weeks from a date
• convert dates between time zones
• localize date formatting for multiple languages
• compare and test dates in unit tests with mocked now
• parse and format RFC 2822 or ISO dates

When to choose

• you write PHP and need richer date handling than DateTime
• you need human-readable relative dates in many languages
• you use Laravel or Symfony and want idiomatic date handling
• you need immutable date objects to avoid mutation bugs

When to avoid

• you work outside PHP
• you only need trivial date formatting already covered by DateTime
• you need a language-agnostic date library for JavaScript or Python
