Cldr Dates & Times

Cldr Dates & Times v1.2.0 Cldr.Date View Source

Provides an API for the localization and formatting of a Date struct or any map with the keys :year, :month, :day and :calendar.

Cldr.Date provides support for the built-in calendar Calendar.ISO. Use of other calendars may not produce the expected results.

CLDR provides standard format strings for Date which are reresented by the names :short, :medium, :long and :full. This allows for locale-independent formatting since each locale may define the underlying format string as appropriate.
