==Spring paschal feasts==
Often considered the most important Christian observance, Spring paschal feasts are a fixed number of days before or after [[Easter Sunday]], which [[Computus|varies by 35 days]] since it depends partly on the [[Lunisolar calendar|phase of the moon]] and must be [[Computus|computed each year]].  In the [[Hebrew calendar]], the new moon of [[Aviv]], spring, is fixed as the [[Lunar New Year#Middle East/West Asia|Lunar New Year]], and the month is called [[Nisan]].  The 14 of Nisan is the [[paschal full moon]], the day of the [[Pesach seder]], a ritual meal [[Haggadah|telling the story]] of [[the Exodus]] from Egypt.  It is one of the [[Three Pilgrimage Festivals|three pilgrimage festivals]] incumbent on all Jewish males living in the land of Israel.  For this observance of this [[mitzvah]], commandment, Jesus and the disciples went to Jerusalem, and held a festive meal known as the [[Last Supper]] on Passover night according to the [[gospel of John]] (or the day before according to the [[synoptic gospels]]).

[[Quartodeciman]] Christians continued to end the [[Lenten fast]] in time to observe the [[Christian observance of Passover|Passover (Christian)]], which occurs before the [[Lord's day]], as the two are not mutually exclusive.  However, due to intense persecution from [[Nicene Christianity]] after the [[Easter controversy]], the practice had mostly died out by the 5th or 6th century, and only re-emerged in the 20th century.

In [[Eastern Christianity]] (including the Eastern Orthodox Church, the Oriental Orthodox Churches, the Assyrian Church of the East, and the Eastern Catholic Churches), these moveable feasts form what is called the [[Paschal cycle]], which stands in contrast to the approach taken by [[Western Christianity|Catholic and Protestant Christianity]].
