Instance Method Details

#translate(format = :default, options = {}) ⇒ Object Also known as: tr

The translation of the date can use one of the formats:

Using the Symbol to pull the default format defined in the config:

date.translate(:verbose)

Using a string with format with native Date elements

date.translate("%m/%d/%Y")

Or using a string with tokens:

date.translate("{month_name} {days::ord}")

The last allows you to use language cases to get something like “on March 1st”.
