DateTime::Calendar::FrenchRevolutionary::Locale::en -- English localization for the French revolutionary calendar.


  use DateTime::Calendar::FrenchRevolutionary::Locale;
  my $english_locale = DateTime::Calendar::FrenchRevolutionary::Locale->load('en');

  my $english_month_name =$english_locale->month_name($date);


This module provides localization for DateTime::Calendar::FrenchRevolutionary. Usually, its methods will be invoked only from DT::C::FR.

The month names come from Thomas Carlyle's book. Most of the feast names come from Alan Taylor's web site, later checked with Wikipedia and with Jonathan Badger's French Revolutionary Calendar module written in Ruby. The day names are from this module's author.


This module provides the following class methods:

  • new

    Returns an object instance, which is just a convenient value to be stored in a variable.

    Contrary to the widely used Gregorian calendar, there is no need to customize a French Revolutionary calendar locale. Therefore, there are no instance data and no instance methods.

  • month_name ($date)

    Returns an English translation for $date's month, where $date is a DateTime::Calendar::FrenchRevolutionary object.

  • month_abbreviation ($date)

    Returns a 3-letter abbreviation for the English month name.

  • day_name ($date)

    Returns an English translation for the day name.

  • day_abbreviation ($date)

    Returns a 3-letter abbreviation for the English day name.

  • feast_short ($date)

    Hopefully returns an adequate English translation for the plant, animal or tool that correspond to $date's feast.

    Note: in some cases, the feast French name is left untranslated, while in some other cases, the translation is inadequate. If you are fluent in both French and English, do not hesitate to send corrections to the author.

  • feast_long ($date)

    Same as feast_short, with a "day" suffix, as in the current calendar's "groundhog day" or "Colombus day".

  • feast_caps ($date)

    Same as feast_long with capitalized first letters.

  • on_date ($date)

    Gives a small text about the events which occurred the same month and day as $date between the calendar's epoch (22 Sep 1792) and the day it was rescinded (31 Dec 1805).

    Most of these events come from an anonymous propaganda book published in year VIII (1799--1800). The others are common knowledge available in any French History book or any encyclopedia.
