For many people, Easter seems to be over almost as soon as Easter Sunday ends. The chocolate disappears, schools go back, and ordinary routines quickly resume. In the Catholic Church, however, Easter is not confined to a single day. It is a season, and a long one: 50 days in all, beginning on Easter Sunday and ending with Pentecost. In 2026, that means Easter began on 5 April and continues until Pentecost Sunday on 24 May.

That may come as a surprise even to some practising Catholics. Yet the Church’s liturgical calendar treats the resurrection not as a brief moment to be commemorated and then set aside, but as a mystery so central that it unfolds over weeks. Easter lasts from the Sunday of the Resurrection until the feast of Pentecost, which commemorates the descent of the Holy Spirit upon the apostles, Mary and the first followers of Christ.

The first stage of this season is the Easter octave, the eight days from Easter Sunday to the Second Sunday of Easter, now also widely known as Divine Mercy Sunday. These days are celebrated by the Church as solemnities of the Lord, in effect extending the joy of Easter Day across a full week.

The wider Easter season then continues through the Ascension and reaches its fulfilment at Pentecost. The Ascension falls on the 40th day of Easter, though in some places it is observed on the Thursday itself and in others transferred to the following Sunday. In 2026, it is celebrated either on 14 May or 17 May, depending on local practice. Pentecost, from a Greek word meaning “50th”, brings the 50-day Easter season to its formal conclusion.

There is also an older liturgical perspective worth noting. In the traditional Roman rite, Easter is more properly called Paschaltide. This older reckoning includes the season of Easter, Ascensiontide and the octave of Pentecost, effectively extending the celebration by another week beyond Pentecost Sunday in the post-Vatican II calendar. In that form, the octave of Pentecost continues until the following Saturday, which in 2026 falls on 30 May.

All of this means that the instinct to wish someone a happy Easter well after Easter Sunday is not a mistake at all. Liturgically speaking, the Church is still celebrating. The resurrection is given time to breathe, to shape prayer, and to settle into the life of the faithful before the year moves on. In a culture that tends to compress feasts into a single day, the Church insists on something more expansive: Easter is a season to be dwelt in.

So when does Easter officially end? In the ordinary Catholic calendar, it ends with Pentecost. In the traditional Roman rite, it lasts through the octave of Pentecost. Either way, the point is the same. Easter is not over in an afternoon. The Church celebrates the resurrection as a season of joy, one long festival of the risen Christ.
