## What it is
A Ruby gem providing complete date, time, and datetime validation for Rails and ActiveModel, supporting multiple ORMs and custom date/time formats via the timeliness parser. It handles timezones, type casting, I18n error messages, and fixes Rails date/time select issues.

## Use cases
- validate date of birth is at least 18 years ago in a Rails model
- validate a datetime field falls between business hours
- restrict a booking date to today or later
- validate a time attribute is before another attribute
- add custom date/time format parsing to Rails validations
- validate dates and times with I18n error messages

## When to choose
- you need thorough date/time/datetime validation beyond Rails' built-in validates_inclusion_of hacks
- you need before/after/between restrictions with dynamic values like lambdas or method symbols
- you need timezone-aware type casting of validated values
- you use ActiveRecord, Mongoid, or other ORMs with ActiveModel

## When to avoid
- you only need simple presence validation on date fields
- you are not using Rails or ActiveModel
- you need JavaScript or client-side date validation instead of server-side
