Overview

CreditCardValidations Expiration

Slim parser+validator for card expiration dates.

exp = CreditCardValidations::Expiration.parse('09/27')
exp.valid?              # => true
exp.expired?            # => false
exp.last_day            # => Date.new(2027, 9, 30)

A card is valid through the *last day* of its expiration month, matching how issuers and networks interpret it.
