v0.2.2

• TimeOfDay#- accepts TimeOfDay to return difference in seconds

v0.2.1

• Add TimeOfDay arithmetic (+, -), advance, change, to_seconds, .from_seconds
• Add YearMonth#advance, YearMonth#change, YearMonth#days
• Add MonthDay#change
• Add #as_json to all value classes

v0.2.0

Breaking: Rails integration extracted to date_values-rails.

require 'date_values/rails' now requires installing the date_values-rails gem.

bundle add date_values-rails

v0.1.4

• Cast returns nil for invalid input instead of raising, following Rails convention
• Add date_value validator to distinguish "invalid input" from "no input"
• #inspect now uses #<ClassName value> format following Ruby convention
• Works with Rails standard validators (comparison, inclusion, exclusion)

v0.1.3

• Fix ActiveRecord type registration — use ActiveSupport.on_load(:active_record) to register types regardless of load order
• Values now work directly in ActiveRecord queries (Shop.where(billing_month: YearMonth.new(2026, 3)))

v0.1.2

• Add #strftime to YearMonth, MonthDay, and TimeOfDay
• Add I18n backend extension for Rails l helper — looks up year_month.formats, month_day.formats, and time_of_day.formats in locale files

v0.1.1

• Add .from class methods for converting from Date / Time (YearMonth.from(date), MonthDay.from(date), TimeOfDay.from(time))

v0.1.0
