/*There are three ranks of feast in Catholic Church.They are in order Solemnity, Feast and Memorial.
*
* Solemnity has three types: solemnity of the Lord, solemnity of Our Lady and solemnity of other saints.
* Solemnities of the Lord have precedence over those of Our Lady and those of Our Lady have precedence over those of other saints.
* The solemnities of the Lord will replace the celebration of a Sunday in Ordinary Time.
* The solemnities of Our Lady and the ones of other saints will be transferred to the next free day if it falls on a Sunday,
* except the following solemnities:
* - Blessed Virgin Mary Mother of God (01/01)
* - Assumption of Our Lady(15/08)
* - Nativity of St John the Baptism(24/06).
* - Sts Peter and Paul(29/06)
* All feasts or memorial is transferred to the next free day if it falls on a Sunday or a same day of a higher ranking feast.
* There are two types of memorial: normal and optional. An optional memorial is celebrated by the faithful's choice.
*
* - The Sunday between 02/01 and 08/01 is the Solemnity of Epiphany of the Lord.
* - The Sunday after 06/01 is the Feast of Baptism of the Lord.
* - The Sunday between 25/12 and 31/12 is the Feast of Holy Family.If there is no Sunday in that period then Holy Family is on 31/12.
*
* There are 4 solemnities for Lord in Ordinary Time period.
* -- Trinity Sunday: Sunday after Pentecost (17 May to 20 June).
* -- Most Holy Body and Blood of Christ or Corpus Christi: Sunday after Trinity Sunday
* -- Most Sacred Heart of Jesus: Friday after Corpus Christi.
* -- Our Lord Jesus Christ, King of the Universe: 34th Sunday of Ordinary Time.
