NAME

Date::Easter - Provides routines to calculate the dates of Easter and related events in the Christian calendar

SYNOPSIS

use Date::Easter;
say Easter 2022; # OUTPUT: «2022-04-17␤»

DESCRIPTION

Date::Easter is a module which provides a subroutine to calculate the dates of Easter in the Christian calendar. The sub returns a Raku Date object.

The routine's code is the Raku version of the algorithm shown at Isn’t there a simpler way to calculate Easter?. The website is a treasure trove of calendar information, courtesy of the very generous and talented Claus Tøndering, to whom I am greatly indebted.

Another routine returns a hash of Date::Events for use with the Calendar module. The hash is keyed by a Date with each key's value an array of Date::Event objects whose attributes describe the Lenten and post-Lenten Christian celebratory events of:

• Ash Wednesday

  The beginning of Lent [46 days before Easter]

• Palm Sunday

  Jesus Christ's entry into Jerusalem [the Sunday before Easter]

• Good Friday

  Jesus Christ's crucifixion [the Friday before Easter]

• Easter Sunday

  The resurrection of Jesus Christ

• Ascension

  The ascension into Heaven of Jesus Christ [40 days after Easter]

• Pentecost

  The descent of the Holy Sprit upon the Virgin Mary and the Disciples of Jesus Christ [50 days after Easter]

The subroutine exporting all the events

sub get-easter-events-hashlist(:$year --> Hash) is export {...}
