This happens anytime the Sunday following Passover falls later than April 25th on our calendar. On those rare occasions Easter is celebrated the month before.
The 14th of the paschal lunar month is designated by convention as the Paschal full moonalthough the 14th of the lunar month may differ from the date of the astronomical full moon by up to two days. The Gregorian calculation of Easter was based on a method devised by the Calabrian doctor Aloysius Lilius or Lilio for adjusting the epacts of the moon,  and has been adopted by almost all Western Christians and by Western countries which celebrate national holidays at Easter.
This was designed to match exactly the Gregorian calculation. Controversies over the date Main article: Easter controversy A five-part Russian Orthodox icon depicting the Easter story. Eastern Orthodox Christians use a different computation for the date of Easter than the Western churches. The precise date of Easter has at times been a matter of contention. By the later 2nd century, it was widely accepted that the celebration of the holiday was a practice of the disciples and an undisputed tradition.
The Quartodeciman controversy, the first of several Easter controversiesarose concerning the date on which the holiday should be celebrated. According to the church historian Eusebiusthe Quartodeciman Polycarp bishop of Smyrna, by tradition a disciple of John the Apostle debated the question with Anicetus bishop of Rome. The Roman province of Asia was Quartodeciman, while the Roman and Alexandrian churches continued the fast until the Sunday following the Sunday of Unleavened Breadwishing to associate Easter with Sunday.
Neither Polycarp nor Anicetus persuaded the other, but they did not consider the matter schismatic either, parting in peace and leaving the question unsettled. Controversy arose when Victorbishop of Rome a generation after Anicetus, attempted to excommunicate Polycrates of Ephesus and all other bishops of Asia for their Quartodecimanism.

According to Eusebius, a number of synods were convened to deal with the controversy, which he regarded as all ruling in support of Easter on Sunday. Victor's attempted excommunication was apparently rescinded, and the two sides reconciled upon the intervention of bishop Irenaeus and others, who reminded Victor of the tolerant precedent of Anicetus. Quartodecimanism seems to have lingered into the 4th century, when Socrates of Constantinople recorded that some Quartodecimans were deprived of their churches by John Chrysostom  and that some were harassed by Nestorius.
But both those who followed the Nisan 14 custom, and those who set Easter to the following Sunday had in common the custom of consulting their Jewish neighbors to learn when the month of Nisan would fall, and setting their festival accordingly. By the later 3rd century, however, some Christians began to express dissatisfaction with the custom of relying on the Jewish community to determine the date of Easter.
The chief complaint was that the Jewish communities sometimes erred in setting Passover to fall before the Northern Hemisphere spring equinox. First Council of Nicaea This controversy between those who advocated independent computations, and those who wished to continue the custom of relying on the Jewish calendar, was formally resolved by the First Council of Nicaea inwhich endorsed changing to an independent computation by the Christian community in order to celebrate in common.
This effectively required the abandonment of the old custom of consulting the Jewish community in those places where it was still used. Epiphanius of Salamis wrote in the mid-4th century: They passed certain ecclesiastical canons at the council besides, and at the same time decreed in regard to the Passover that there must be one unanimous concord on the celebration of God's holy and supremely excellent day.
For it was variously observed by people  That the older custom called "protopaschite" by historians did not at once die out, but persisted for a time, is indicated by the existence of canons  and sermons  against it.
Dionysius Exiguusand others following him, maintained that the Bishops assembled at the Nicene Council had specified a particular method of determining the date of Easter; subsequent scholarship has refuted this tradition. It took a while for the Alexandrian rules to be adopted throughout Christian Europe, however. So the church leaders decided, at the Council of Nicea into take matters into their own hands: In rejecting their custom, we may transmit to our descendants the legitimate mode of celebrating Easter… We ought not, therefore, to have anything in common with the Jews, for the Savior has shown us another way….
We desire, dearest brethren, to separate ourselves from the detestable company of the Jews.
The Nicean Council decided that they would celebrate a separate festival on the first new moon after the Spring Equinox, which is always March 21st in the Gregorian Calendar to make a deliberate break with the people of Israel. We are not judged for not celebrating the Passover, but we miss out on many treasures that God placed in his word for us to learn from.
Sadly, the Nicean Council decided on behalf of all Christians from that time onwards that Passover had no relevance for them. The two were severed apart, and the evil root of anti-semitism crept into Christianity. Sadly, for much of church history, Jewish people were persecuted, tortured and murdered at the hands of Christians for simply being Jewish.
Jews and Gentiles draw together in Yeshua However, we live in exciting days and the last century has seen some colossal steps forward in healing the terrible rift between Jew and Gentile.
More Jewish people have come to believe in Yeshua as Messiah in the last 19 years than in the previous 19 centuries combined!
And many Gentile believers are now taking more interest in the Jewish foundations of their faith.

Many churches hold Passover seders, explaining more about the feast, and there has been considerably more appreciation of the people of Israel since the Bible became widely translated and published in the last few centuries. The additional month is needed because the Jewish calendar year has less days than the solar year and begins to slip out of gear with the seasons.
The extra month thus realigns the Jewish calendar year with the seasons of the solar year. This is important because the Jewish holidays are closely related to the seasons. For example, the Torah commands that Passover be celebrated in the spring. Every so often the Jewish leap year will push Passover so far into April that a second full moon following the vernal equinox would appear before the Sunday following Passover. This happens anytime the Sunday following Passover falls later than April 25th on our calendar.
On those rare occasions Easter is celebrated the month before Passover rather than the Sunday following Passover. How did this system for determining the date for Easter originate? The early church was faced with the following conflict in dates:
