The Season of Easter

Celebrating the Resurrection of the Lord
Easter Season begins on Easter Day and lasts 50 days, ending on Pentecost. Thus in 2021  it begins on 4 April 2021  and ends on 23 May 2021 .
In most churches, the decorations are white, gold, or white and gold. White represents the angels who announced the resurrection, while gold symbolizes triumph. You can read more about color in worship
Scripture Readings:
The Revised Common Lectionary appoints Scripture readings for use in worship during the Season of Easter.

The East:

Orthodox churches use the Julian calendar to calculate Easter Day and adjust the date so that it falls after the Jewish Passover. For them, Easter Season also lasts fifty days, ending on Pentecost.
Special Days:
Ascension Day, the fortieth day of Easter, thus always a Thursday ( 21 May 2020 ).
Pentecost, the fiftieth day of Easter, thus always a Sunday ( 31 May 2020 ).

During Easter Season, the theme of worship is the Resurrection of Jesus Christ from the dead.

Throughout this discussion, please note that Easter and Passover are the same thing. They fall on different dates, for reasons you will shortly learn, and they have different names only because this article is in English.

According to scripture, Jesus rose from the dead on the first Sunday following Passover. See Matthew 28:1, Mark 16:1-3, Luke 23:56-24:3, and John 20:1. For this reason, ancient Christians celebrated Easter (which they called Passover) on the first Sunday after the Jewish Passover, which is 14 Nisan on the Jewish calendar. The only exceptions were in Syria and Mesopotamia, where ancient Christians celebrated Easter on 14 Nisan, no matter which day of the week it happened to be.

No one in ancient times denied that the Resurrection took place on a Sunday.

According to scripture, the month of Nisan—and therefore the date of Passover—is linked to the spring harvest in Palestine. (See Exodus 12:1-3, Leviticus 23:9-14, and Numbers 28:16.) However, the Romans banished all Jews from Palestine after the rebellion of Simon Bar Kochba in AD 135, making it difficult for the rabbis to determine the proper date for Passover. So sometime around AD 200, the rabbis reformed the Jewish calendar. Relative to the Julian calendar, which was the Roman civil calendar, the new Jewish calendar allowed Passover to precede the spring equinox and it allowed two Passovers in the same twelve-month period. Obviously, the spring harvest cannot precede the spring equinox! Shortly after AD 300, the rabbis revised the Jewish calendar again, but it was still possible to have two Passovers in one twelve-month period, as defined by the Julian calendar.

By this time, the vast majority of Christians had cLong since given up using the Jewish calendar to determine the date of Easter. Instead, they figured it independently. They reasoned that at the time of the Last Supper, Nisan began with the new moon after the spring equinox. The full moon occurs on the fourteenth day, which would have been the Jewish Passover. According to Scripture, Jesus rose from the grave on the Sunday that immediately followed. So they celebrated the Resurrection on the first Sunday after the first full moon that followed the spring equinox. However, since there was no standard way to calculate the spring equinox, it was still possible for different regions to celebrate Easter on different Sundays. This was a problem, because Christians who lived on the edges of these regions got into unseemly disputes, and intellectual pagans derided Christians for not being able to figure out their own holy days. In those days, of course, Christianity was a minority religion for which the public did not have much respect and disputes about Easter weren’t helping evangelism.

Meanwhile, the churches in Syria and Mesopotamia were still celebrating Easter on 14 Nisan as determined by the current Jewish calendar, regardless of the day of the week. They believed they had apostolic direction to celebrate Easter on the same day that the Jews celebrate Passover, even if the Jews calculated the date incorrectly.

In AD 325, the Council of Nicæa was convened to deal with Arianism and to standardize the date of Easter. The Council of Nicæa, noting that Syria and Mesopotamia represented a small minority, required them to conform to the practice of the majority. The bishops from Syria and Mesopotamia readily agreed to this ruling and their churches complied with it. The Council of Nicæa also ruled that all churches must celebrate Easter on the same day. This clearly implies that they instituted a standard method for calculating the date of the full moon after the spring equinox, but the documentary evidence for it has not survived. Some ancient writers, notably Ambrose, felt that the Council of Nicæa prescribed the mathematical formula that we presently use to fix the date of Easter, but we can no longer prove it.

The Western Church applies the Nicene formula to the calendar as reformed by Pope Gregory in 1582. (This calendar reform resulted in the Gregorian calendar that we use today for secular purposes.) The Eastern Church applies the Nicene formula to the old Julian Calendar, which was instituted by Julius Caesar and served as the civil calendar of the Roman Empire before the birth of Christ. The Eastern Church also applies the formula in such a way that Easter always falls after the Jewish Passover.

There are at least two serious proposals to standardize the date of Easter. One is to institute a new method of calculating the lunar cycle, based on the moon as it appears over Jerusalem, so that eastern and western Easter would always fall on the same date. The other proposal is to fix Easter as the second Sunday in April.

The important holy days during Easter are as follows:

Roughly speaking, the western Church consists of Protestants, Catholics, and Anglicans. The eastern Church consists of the Eastern Orthodox churches, the Oriental Orthodox churches, and the eastern-rite churches affiliated with the Roman Catholic Church.


Pentecost is a Jewish festival that falls on the fiftieth day of Passover. In biblical times, Jews from all over the Roman Empire gathered in Jerusalem for the festivities of Pentecost. On the Pentecost after Jesus’ resurrection—ten days after Jesus had ascended into heaven—the apostles and other believers were gathered together in one place, when they were suddenly empowered by the Holy Spirit to preach the gospel. They went out into the crowds and attracted attention by preaching in the native languages of all the people present. This created quite a stir. Peter seized the opportunity to address the crowd, preached Jesus’ death and resurrection, and won several thousand converts.

These events are recorded in Acts 2:1-41.

Accordingly, Pentecost is celebrated by Christians as the birthday of the Church by the power of the Holy Spirit. Since the Jewish Pentecost is the fiftieth day of Passover, the Christian Pentecost is the fiftieth day of Easter.

Pentecost is not the coming of the Holy Spirit. The Holy Spirit made His first appearance in Genesis 1:2! Rather, Pentecost is the outpouring of the Holy Spirit on human flesh to give birth to the Church.

How to determine the date of Easter Day

This method is valid for any year, but only for the Western Church.

Take the number of the year and divide by 19. Discard the answer and add 1 to the remainder. Look up the answer in the following table. Easter is the first Sunday after the date in the table. For example, 2020 divided by 19 is 106 with a remainder of 6. Add 1 and the answer is 7. The date in the table for 7 is April 8. Therefore, Easter Day falls on the following Sunday, which is April 12, 2020.

         0 —          10 —
         1 —          11 —
         2 —          12 —
         3 —          13 —
         4 —          14 —
         5 —          15 —
         6 —          16 —
         7 —          17 —
         8 —          18 —
         9 —          

There is a way to reduce this to a single mathematical formula, but I thought you’d prefer a method that even ordinary mortals can use. Once you know the date of Easter, you can determine the dates of holy days that occur at fixed intervals before or after Easter:

Here is a handy table for 2021 — 2025 :

Year   Ash Wednesday   Easter   Ascension   Pentecost   Trinity
  2020 February 26 April 12 May 21 May 31 June 7
  2021 February 17 April 4 May 13 May 23 May 30
  2022 March 2 April 17 May 26 June 5 June 12
  2023 February 22 April 9 May 18 May 28 June 4
  2024 February 14 March 31 May 9 May 19 May 26

The English Word Easter

Easter is an English word derives from the name of a Germanic goddess, and you won’t get any argument from me if you think the word should be deprecated because of its association with pagan fertility rites. On the other hand, the Old Testament book of Esther is named after a Jewish heroine who bore the name of the goddess Ishtar! In the ancient Church, the celebration of the Resurrection was called Passover. Today, Orthodox Christians call this holiday the Pasch (as in paschal lamb ), which is the Greek word for Passover. In Anglican churches, the designation Sunday of the Resurrection is often preferred over Easter and in Lutheran liturgy, it is called The Resurrection of Our Lord.

The current ecumenical trend in English-speaking countries is to use Easter for the fifty-day season and Easter Day for the day of the Resurrection.

Aside from English and German, the words for Passover and Easter are the same in most languages.
