How to configure error messages to check subparameters of numerical values?

How to configure error messages for auxiliary parameters when checking the numerical value of a field in the ActiveRecord model?

Example:

validates :month, :numericality => {
  :greater_than_or_equal_to => 1,
  :less_than_or_equal_to    => 12
}

In this case, if the "month" attribute is greater than 12, I want to provide a custom error message instead of the default value "must be less than or equal to 12". How to achieve this?
