Eastertide is fifty day period from Easter to Pentecost. It is celebrated as a single joyful feast. Each Sunday of the season is treated as a Sunday of Easter, and, after the Sunday of the Resurrection, they are named Second Sunday of Easter, Third Sunday of Easter, etc. up to the Seventh Sunday of Easter, while the whole fifty-day period concludes with Pentecost Sunday.

The first 40 days end with the feast of Ascension, which is celebrated on the Thursday of the sixth week of Resurrection. This 40-day period is dedicated to the mystery of the various and numerous appearances of the resurrected Savior. During the forty days between His Resurrection and Ascension, Jesus Christ appeared and showed Himself to his disciples and prepared them for the task of carrying on His work and preaching His Gospel. He did this in each one of the appearances described in the Gospels (Luke 24:13-35, John 20:19-23, 24-31). Jesus Christ was on earth after He was raised from the dead, He showed Himself to many people.

1. To 500 people who saw Him at one time (1 Corinthians 15:6)
2. To Mary Magdalene (John 20:14-16)
3. To the women returning from the tomb (Matt. 28:8-18)
4. To Peter (Luke 24:34)
5. To His followers toward evening (Luke 24:33-36).
6. To the two followers on the road to Emmaus (Luke 24:13-31).
7. To all the apostles eight days after His Resurrection (John 20:26).
8. To seven by the lake of Tiberias (John 21:1-23).
9. To James (1 Corinthians 15:7)
10. To the eleven (Matt. 28:16-20)
11. To Stephen outside Jerusalem (Acts 7:55).
12. To Paul near the city of Damascus (Acts 9:3-6)

The Fathers of the Church have placed five feasts during this 40-day period. These feasts are:

1. The Beheading of John the Baptist
2. New Sunday
3. Green Sunday
4. Red Sunday

And I will be with you always to the end of the age” (Matt. 28:19-20).
