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. A final hiccup occurred, however, in the late s, when Pope Gregory XIII instituted a new Gregorian calendar that correctly assessed a solar year to be The older Julian calendar put a solar year at
Calculating the Date of Easter
This week, as they so often do, my Sunday School class of bright and year-olds posed a tough question: why did Easter fall on Evan’s birthday last year, but it’s falling on Abby’s birthday this year? Though I couldn’t answer on the spot, I knew I had a secret weapon back at the office—saved for just such an occasion: a short article by Farrell Brown, a retired chemistry professor with an interest in the historical interactions between science and religion.
Here, as a public service for those still scratching their heads over the calendrical wandering of Easter, is Dr. Brown’s answer to my Sunday School kids’ question—and thrown in for free, the story of why Easter dates still differ in different parts of the world:. The date of Easter Sunday, a so-called movable feast day in the Christian Church year, may seem mysterious to many who celebrate it.
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.

Calculating the Easter Date
However, in certain parts of England and in Scotland, the festival is celebrated on March 25th, and in other parts of Europe on the 28th of April. The advantages of Easter following the vernal equinox should be so great as would enable the festival to be retained as long as a few years. The observatory of Paris is said to have been established at the same time as that of Rome, and there are also those who say that Easter is the first day of March, which they consider to be the most probable.
Easter is a Christian holiday that celebrates the belief in the resurrection of Jesus Christ. In the New Testament of the Bible, the event is said to have occurred three days after Jesus was crucified by the Romans and died in roughly 30 A. Although a holiday of high religious significance in the Christian faith, many traditions associated with Easter date back to pre-Christian, pagan times. Easter typically falls on the first Sunday after the first full moon occurring on or after the spring equinox.
Eastertide ends on the 50th day after Easter, which is known as Pentecost Sunday. Despite its significance as a Christian holy day, many of the traditions and symbols that play a key role in Easter observances actually have roots in pagan celebrations—particularly the pagan goddess Eostre—and in the Jewish holiday of Passover. The resurrection of Jesus, as described in the New Testament of the Bible , is essentially the foundation upon which the Christian religions are built.
Now that the weather is warming up, the birds are singing, and the flowers are blooming, our minds are starting to fast-forward straight to summer. C’mon, how can you not?! Well, Easter , that’s why. This year, spring starts on March 19, but the season’s most celebrated holiday isn’t for weeks after that. And if you’re anything like us, you’re probably wondering the exact same thing Unlike fixed holidays like Halloween and Christmas, Easter is considered a “moveable feast and can fall anywhere from March 22 and April 25,” according to The Old Farmer’s Almanac.
In most years Protestant and Roman Catholic Christians celebrate Easter on one date, and Orthodox Christians on another (the year , and again in
It also marks the first day of Lent, a period of 40 days over which Christians are to spiritually prepare for Easter. Count 40 days ahead. Ascension Day is a Christian holiday that falls exactly 39 days after Easter Sunday. Easter has always been celebrated near the date of the Jewish Passover, but the exact method of determining the date on which to celebrate Easter has changed slightly over the centuries.
Easter is a celebration of Christ’s return from the dead after His crucifixion. Passover begins on the fifteenth day of the month of Nisan in the Hebrew calendar. This roughly corresponds to the first full moon after the March equinox, but the Hebrew calendar is not based on the cycles of the moon, so the timing is not exact. Since the date of Passover needed to be announced each year by Jewish officials, early Christian leaders simplified the date of Easter by scheduling it consistently for the Sunday after the full moon.
This happened in CE and was an official declaration of the Council of Nicaea. Religious dates were never previously established using astronomical events in the Jewish tradition from which most of Christian tradition arose. The practice of doing so was pagan in nature, but early Christians adopted it for the sake of simplifying their own dating system. Note the difference between Gregorian and Julian calendars.
Most Western churches Roman Catholics and most Protestants follow the standard calendar, also known as the Gregorian calendar. Some Orthodox Christian churches still use the Julian calendar to determine the date of Easter.

Date of Easter. Introduction The problem of finding the date of Easter is not an easy one. The date depends on both the Gregorian calendar in which there is a leap year every four years, except for century years where only one in every four is a leap year and the Jewish calendar which follows a solar cycle for years and lunar cycle for months – it has a year cycle in which the 3, 6, 8, 11, 14, 17 and 19 years have a thirteenth month.
In the Bible St. Luke, Chapter 22 we have a description of how Jesus ate the Passover with his disciples before going to Gethsemane.
Easter falls on the first Sunday after the Full Moon date, based on mathematical calculations, that falls on or after March If the Full Moon is.
Easter falls on the first Sunday following the Paschal Full Moon, the full moon on or after 21 March, taken to be the date of the vernal equinox. The Western calculation uses the Gregorian calendar, while the Eastern calculation uses the Julian calendar, whose 21 March now corresponds to the Gregorian calendar’s 3 April.
How are the dates for Easter, Palm Sunday, and Ash Wednesday determined?
Jesus rose from the dead on the first Sunday following the feast of Passover. Technically, he may have risen Saturday night, but that still counts as Sunday on the Jewish reckoning, which begins each day at sunset instead of at midnight. The date of Passover is a complicated thing. Theoretically, the date should be the 14th of the Jewish month of Nisan, and it should correspond to a full moon the Jewish calendar being partly lunar.
Easter is the most important Christian Holyday, celebrating the resurrection of Jesus Christ. Christian authorities have always wanted to celebrate this on the same.
When is Easter? What is Easter? Easter is the most important Christian Holyday, celebrating the resurrection of Jesus Christ. Christian authorities have always wanted to celebrate this on the same day of the year as the true resurrection. But at the time and place of the crucifiction our “normal” calendar was not used, but the Hebrew calendar, which is still in use by the Jews today. The Hebrew calendar is based on the Moon, and each month starts at new moon, i. To keep in synchronisation with the seasons, a leap month is added approximately once every 3 years.
Due to this definition, the 15th day of every Hebrew month is a full moon day. On the Hebrew calendar, the first month of the year is always the month that starts on the new moon that is closest to the beginning of spring, this month is called Nisan. See www.
