Second, the rituals associated with Easter brought into sharp contrast the differing dates of its observance. Conflict developed when one group of Christians ended their fasting before another group ended theirs. Those who calculated Easter with the Jewish calendar came to be known as Quartodecimans — named for the number 14 because Passover begins at the close of the 14th day of the month of Nisan. In the second century, Quartodecimans — centered in Jerusalem and modern-day Turkey — claimed they received their tradition from the apostle John. In , the Council of Nicea had forged a compromise between proponents of lunar and solar calendars: placing Easter on the first Sunday following the first full moon lunar after the Spring Equinox solar. Christians in Rome believed the Spring Equinox fell on March Believers in Alexandria, Egypt, placed it on March 21, 19th-century church historian Karl Hefele wrote. Romans, unlike Alexandrians, also waited a week to celebrate Easter when the full moon following the equinox fell on Saturday.
Why Calculating Easter’s Date Is So Complicated
In order to understand the dating conflict of Easter, we have to look at the issue of the calendar. Actually, the dating of Easter is complex and a result of using both lunar and solar calendars. The early Romans used a lunar calendar in which months alternated between 29 and 30 days.
Easter varies from March to April each year. Experts say the date has to do with the lunar cycle and finds its origin from the Jewish Passover.
Skip navigation! Story from Spirit. In , Easter falls on April 21 — a full three weeks later than Easter in , which fell on April 1.

This year, Easter will be observed on Sunday, April It so happens that Easter is most celebrated on either March 31 or April 16 over a year period from to AD. Many Eastern Orthodox churches follow the Julian calendar rather than the Gregorian. Specifically, Easter is celebrated on the first Sunday following the full Moon that occurs on or just after the spring equinox.
The first full Moon to occur after that date rises the night of Tuesday, April 7.
The ecclesiastical rules are: Easter falls on the first Sunday following the first ecclesiastical full moon that occurs on or after the day of the vernal equinox; this.
Because the ancient Egyptians and Hebrews used different calendars. The Egyptians had one based on the movement of the sun, which was passed on through the Romans and Christian culture to become the modern world’s standard. The Jews had one based on the phases of the moon — as Islam does, which is why the month of Ramadan moves round the calendar and takes places at different times of the year each year, with Muslims waiting for sightings of the moon before they know what day it will begin.
Easter is one of the festivals which tries to harmonise the solar and lunar calendars. As a general rule, Easter falls on the first Sunday, following the first full moon after 21 March. But not always. Easter is the time when Christians celebrate the Resurrection of Christ. According to the gospels he was killed three days before the Resurrection, around the time of the Jewish Passover.
So Christians wanted to have their feast day around the same time as the Jewish festival which was fixed by the first full moon following the vernal equinox — the spring day when night and day are exactly the same length. The problem comes because a solar year the length of time it takes the earth to move round the sun is days, 5 hours, 49 minutes, and 12 seconds whereas a lunar year is Calculating one against another is seriously complicated.
There have been various attempts to reconcile this, including the famous saltus lunae the moon’s jump whereby one of the day months in the lunar cycle gets arbitrarily shortened to 29 days. But the solar and lunar years diverge by 11 days every year.
Question: “How is the date for Easter determined? The four Gospels also make it clear that Jesus was raised from the dead three days later, on the first day of the week Matthew ; Mark ,9; Luke ; John , However, this is not the case.

Easter , the Christian holiday that celebrates the day of the resurrection of Jesus Christ, is a moveable feast, which means that it does not occur on the same date every year. Easter is calculated based on the phases of the moon and the coming of spring. In A. In practice, that means that Easter is always the first Sunday after the first full moon that falls on or after March Easter can occur as early as March 22 and as late as April 25, depending on when the paschal full moon occurs.
The Council of Nicaea decided that Easter must always occur on a Sunday because Sunday was the day on which Christ rose from the dead. But why is the paschal full moon used to determine the date of Easter? The answer comes from the Jewish calendar. The Aramaic word “paschal” means “pass over,” which is a reference to the Jewish holiday. Passover fell on the date of the paschal full moon in the Jewish calendar. Jesus Christ was Jewish. Therefore, the very first Easter Sunday was the Sunday after Passover.

Calculate the Date of Easter Sunday
The Christian festival commemorating the resurrection of Jesus was soon established as an annual celebration, but the date varied among different groups of Christians. Easter would henceforth be on the first Sunday after the first ecclesiastical full moon following the vernal equinox on 21 March. The result is that Easter Sunday never falls on the same date in two successive years, and it may fall on any of the days between 22 March and 25 April inclusive.

The computus Latin for ‘computation’ is a calculation that determines the calendar date of Easter. Determining this date in advance requires a correlation between the lunar months and the solar year , while also accounting for the month, date, and weekday of the calendar. In late antiquity , it was feasible for the entire Christian church to receive the date of Easter each year through an annual announcement from the Pope.
By the early third century, however, communications had deteriorated to the point that the church put great value in a system that would allow the clergy to independently and consistently determine the date for themselves. In The Reckoning of Time , Bede uses computus as a general term for any sort of calculation, although he refers to the Easter cycles of Theophilus as a “Paschal computus. Easter commemorates the resurrection of Jesus , which is believed to have occurred on the third day inclusive after Passover.
