Template:Infobox holiday. Most Christians refer to the week before Easter as ” Holy Week “—it contains the days of the Easter Triduum , including Maundy Thursday , commemorating the Maundy and Last Supper ,   as well as Good Friday , commemorating the crucifixion and death of Jesus. In Eastern Christianity , the season of Pascha begins on Pascha and ends with the coming of the fortieth day, the Feast of the Ascension.
Easter and the holidays that are related to it are moveable feasts which do not fall on a fixed date in the Gregorian or Julian calendars which follow only the cycle of the sun; rather, its date is determined on a lunisolar calendar similar to the Hebrew calendar.

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.
When is Easter 2019 and why does the date change each year?
The Orthodox call this day Pascha. It is the most joyous celebration of the entire year, as the community gathers together to celebrate the Resurrection of Jesus Christ. It decreed that Pascha would be held on the first Sunday after the first full moon occurring on or after the vernal equinox. March 21 is used as an approximation of the vernal equinox.
Pascha is delayed by a week if the full moon is on Sunday.
So, to put it another way: Easter is observed on the Sunday after the Paschal Full Moon. What Happens When the Full Moon and Spring Equinox Occur on the.
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. It was not a precise measure; it gradually fell out of step with the seasons.
Julius Caesar reformed the calendar by switching its base from lunar to solar. The day on which the Vernal Equinox occurred was defined as March 25th. On the new Julian calendar, the length of the year was fixed at days, with an additional leap-year day added every fourth year. This made the average length of a year equal to The annual error of 0.
Under the new system of the Gregorian calendar, March 21, CE became the date of the Vernal Equinox, and the year was shortened by ten days.
How Is the Date of Easter Determined?
Easter will be observed on Sunday, April 12! 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.
How to use Excel to calculate the date for Easter, using worksheet when compared to other methods of determining the date of Easter.
Springtime is the signal for many things: warmer weather, fresh flowers, and for those who celebrate, Easter Sunday. Unlike Christmas, which, as most of us know, falls on December 25 every single year, Easter, and the celebrations leading up to it, change dates. Lifelong and brand new celebrators alike might wonder, “How the Easter date is determined?
Of course, to know when Easter is this year, you can figure it out by taking a step back and figuring out Ash Wednesday’s date. The main event occurs six and a half weeks after Ash Wednesday, encompassing the 40 days of Lent. But to discover what causes all these dates to fluctuate year after year instead of staying in one place like many other annual holidays including Christmas, Valentine’s Day, and St. Patrick’s Day, you might want to look to the sky for your answer.
We’ve investigated the reasons behind the ever-changing date, which includes the phases of the moon, the vernal equinox, and the Gregorian calendar. You might not have realized just how much goes into how Easter Sunday is determined each year!
Ireland’s important role in calculating when Easter falls
Easter is the Christian celebration of the anniversary of the Death and Resurrection of Jesus Christ. For the past years, March 21st has been used to represent the date of the March equinox the real equinox might be a day or two different. There are two equinoxes a year, one in March and one in September.
The date of Easter changes, because the Paschal full moon can fall on Gregorian calendar method and instead follow the Julian calendar.
The calculation of Easter is complicated because it is linked to an inaccurate version of the Hebrew calendar. Jesus was crucified immediately before the Jewish Passover, which is a celebration of the Exodus from Egypt under Moses. Celebration of Passover started on the 15th day of the spring month of Nisan. Jewish months start when the moon is new, therefore the 15th day of the month must be immediately after a full moon.
It was therefore decided to make Easter Sunday the first Sunday after the first full moon after vernal equinox. Note, however, that historically, some countries have used the real astronomical full moon instead of the official one when calculating Easter. This was the case, for example, of the German Protestant states, which used the astronomical full moon in the years

The World Council of Churches proposed a reform of the method of determining the date of Easter at a summit in Aleppo , Syria , in . Under the proposal, Easter would be defined as the first Sunday following the first astronomical full moon following the astronomical vernal equinox , as determined from the meridian of Jerusalem. An example would be the full moon at Jerusalem time on 21 March , after the equinox at Jerusalem time the same day. The reform would have been implemented starting in , the first year in which the Eastern and Western dates of Easter would coincide after this method was proposed in However, if one begins calculations in , there is a difference in the following year: the Aleppo method gives Easter Sunday as 19 April ; in this case Western Christians who celebrated on 12 April that year would have had to change their date while Eastern Christians would not, a phenomenon which would also apply in , , , , , , etc.
The proposal will have the effect of slightly widening the range of dates on which Easter could be celebrated; while the current extremes are 22 March and 25 April, the range would widen by one date on each side. These new dates, however, would be extremely uncommon: commencing calculations from , the first occurrence of Easter on 26 April would be in a year in which under the Gregorian method Easter falls on 19 April ,  while the first occurrence of Easter on 21 March would not be until the year  a year in which under the Gregorian method Easter falls on 25 April .
The Aleppo method would make it possible for Candlemas and Shrove Tuesday to coincide, as Ash Wednesday would fall on 3 February if Easter fell on 21 March in a common year; and also for Laetare Sunday to occur in the month of February, which is not currently possible, as an Easter of 21 March would position Laetare Sunday on 28 February or on 29 February if the 21 March Easter is occurring in a leap year. An Easter of 21 March would also produce an April date for the Feast of the Ascension , occurring on 29 April; although as an April date for the Ascension is already possible as it would occur on 30 April when Easter falls on 22 March, possible under the Gregorian method , this is less noteworthy.
In the 21st and 22nd centuries, it is the years in which the Paschal Full Moon on the Gregorian tables falls on its latest possible date 18 April — the year and every nineteenth year after that — when the Aleppo method gives Easter approximately a month earlier than the Gregorian. In the year which is technically part of the 20th century , however, this is not the case. One might think, based on the occurrences in and every nineteenth year after that, that the Aleppo method would give 26 March as Easter Sunday for This reform has not been implemented.
How are the dates for Easter, Palm Sunday, and Ash Wednesday determined?
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 celebration actually changes dates year-to-year—here’s why. The meaning of Lent is to be “encouraged to find our own method of.

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. As a result, rabbis periodically had to announce when Passover would be celebrated.

Norman Harker adaptation of Claus Tondering Algorithm. As Chip Pearson noted on his website, finding the day of Easter Sunday is a trivial effort but finding the date of a specific Easter Sunday is not such a trivial effort. A portion of the search leads us to Herber’s Excel Forum , which apparently sponsored a contest as referenced in the Excel newsgroups. The rules for that contest were to come up with the shortest Excel worksheet formula that would return the date of Easter Sunday for years between Other formulas presented during that same period that provided the desired results were noted by George Simms , a participant in the contest:.
The Norbert Hetterich formula is presented on Chip Pearson’s site with a minor modification to format the result in typical U. Another interesting formula is attributed to Gerhardt Somitsch presented where cell A2 contains a year value :. The good thing about these various formulas is that they do work for the near future at least through , and that’s all most of us need at this point in time.
However, for dates beyond and earlier than , we must look elsewhere. Before moving on to the other solutions, let us look at the apparent limitations of the various worksheet function solutions. It may very well be that these worksheet functions meet your needs and you don’t need to look further. These limitations have either been stated at some point in their development, as with the contest limits mentioned earlier, or by inspection when compared to other methods of determining the date of Easter.
